Time is off by Minutes/Hours on Logs

Clock Drift: Over time the clock on a X26E can drift. Clock drift is a phenomenon where a specific clock runs faster or slower than a reference clock. All clocks, digital or analog, can drift for various amounts of time based on many factors including; natural component tolerances, environment temperature, power supply, age of components, etc. Periodic time synchronization is needed to keep the time accurate on the CEW. If a CEW is not connected to Evidence Sync for an extended period of time the time shown on logs can be off from what is expected due to the drift of the clock. The time drift on the X26E can be up to +/- 4 minutes per month.

Clock Reset: If a CEW is left without a battery for an extended period of time, the internal clock will reset back to its factory default January 1, 2000 at midnight (based on Greenwich Mean Time, local time may show December 31, 1999). Once power is applied to the CEW again, the clock will begin to run again, with the new reset time reference. This is similar to a microwave oven blinking “12:05” 5 minutes after power returned from an outage. The clock will need to be synchronized to reflect the accurate time again.

Broken Safety

The safety on the X26E is not field repairable. The device will need to be sent to Axon for repair.

P and E CID codes


P = Programming. Programming occurs when a new battery is inserted into the X26 that has an updated firmware. Do not remove the battery while the P code is shown.

Once the P has disappeared, it will go through the boot-up sequence and operate normally.


The E error will occur if there was an error during programming of the device. This generally occurs if the battery was removed during a firmware update.

If you see an E error in the field, the X26E needs to be sent to Axon for inspection.

Laser or flashlight is not working

  • Ensure the unit is Safe and press and hold the selector button for 3-5 seconds.
  • If the CID flashes LF the unit will need to be sent to Axon for inspection.
  • If the CID flashes something other than LF, scroll through the illumination options by pressing the selector button until LF appears.

The Laser and Flashlight should now be working. If not, the unit will need to be sent to Axon for inspection.

00 Error

When the display screen of your X26E shows 00 this indicates that the weapon is not able to read the battery properly.

  • Clean the contacts of the battery and CEW
  • Take a known working battery and insert it into the CEW

If cleaning the contacts and using a new battery do not resolve the 00 error, please send the battery and CEW into Axon for inspection.

0 Error

When the display screen of the X26E shows 0 this indicates that the battery in the device no longer has a charge.

Connect a new battery to your X26E and the new battery percentage will be shown.

E2 error with TCAM

The E2 error is displayed on the CID when the weapon detects that the date/time is off on the weapon. This can occur if the battery has been left out of the device for an extended period of time or that the device has not been connected to Evidence Sync for an extended period of time.

  • Connect the CEW to Evidence Sync and allow it to update the time. This will happen automatically when the device is connected and the logs appear in Evidence Sync.
  • Disconnect the CEW and re-insert the TCAM.If the “E2” disappears, continue normal use.
  • If the E2 error remains, remove the cartridge (if there is one) and the TCAM. Place the safety in the ARMED position and insert the TCAM. After boot-up, and place the safety in the SAFE position.If the “E2” disappears, continue normal use. If not, the TCAM and CEW should be sent to Axon for inspection.

EE Error

The EE error is displayed on the CID when there is a poor battery connection, generally caused by dirty battery contacts.


  • Clean off the connectors on the battery itself and inside the battery bay on the CEW.

E2 Error Code

The E2 error is displayed on the CID when the weapon detects that the date/time is off. This can occur if the battery has been left out of the device for an extended period of time or that the device has not been connected to Evidence Sync for an extended period of time.


  • Connect the CEW to Evidence Sync and allow it to update the time. This will happen automatically when the device is connected and the logs appear in Evidence Sync.

Once the logs appear, no further interaction is needed. The date/time has now been updated.


Changing flashlight and laser settings

The operator can select four modes of illumination when using the X26 ECD.

LF LASER and Flashlight both illuminate

LO LASER only will illuminate

OF Only Flashlight will illuminate

OO Neither the LASER nor the Flashlight will illuminate and the CID display is dimmed

To change the illumination setting:

  • Place the safety switch in the down (SAFE) position, remove the TASER cartridge, and aim the X26 ECD in a safe direction (such as toward the ground). NOTE: The illumination selector is disabled if the safety switch is in the up (ARMED) position.
  • Press and hold the Illumination Selector for approximately 1 second until the CID display illuminates.
  • Press and release the Illumination Selector to toggle through the four available settings until the setting you desire is designated on the CID. Stop when the setting you desire is displayed.
  • The selected mode displays for 5 seconds, and will be the default mode the next time the safety switch is moved to the up (ARMED) position.

Note: Using pens or paper clips to press the Illumination Selector may damage it. Only use your finger to press the Illumination Selector.

Changing the battery pack

The X26 ECD is shipped with the DPM battery pack pre-installed. To change the DPM:

  • Shift the safety switch to the down (SAFE) position.
  • Remove the TASER cartridge.
  • To unload the DPM, depress the DPM release button and remove the DPM from the handle of the ECD.
  • Wait approximately 5 seconds, then install the new DPM. Ensure that the DPM is fully inserted into the X26 ECD. Apply sufficient force to compress the foam gasket and allow the DPM battery pack to seat fully. Verify that the DPM release button pops out from the recessed position with an audible click. Failure to do so could result in a damaged X26 ECD or a loss of power during a deployment. When the DPM is installed, the X26 ECD will cycle through the boot-up sequence.

Viewing status information

When a DPM is inserted in the X26 ECD, the ECD will enter a “boot-up” sequence and cycle through the following information:





07 Current year (2007)

08 Current month (August)

09 Current date (9th)

12 Current hour (GMT)

22 Current minutes

27 Internal temperature of the X26 (27 ºC)

18 X26 software version (18)


Performing a spark test

Spark Test

We recommend conducting a spark test every 24 hours or prior to the start of your shift for your individually issued X26 ECD.

It is not necessary to use an extended duration. As long you see a visible spark between the electrodes (one second), the X26 ECD is functional.

The reasons for the spark test include:

  • To verify the X26 ECD is working.
  • To verify that the DPM battery pack is adequately charged.
  • To energize the components in the high voltage section of the X26 ECD on a regular basis.

Spark Test Instructions

  • Point the ECD in a safe direction.
  • Ensure that the safety switch is in the down (SAFE) position.
  • Ensure that the TASER cartridge is removed. A spark test should never be conducted with a TASER cartridge in the ECD.
  • Ensure that no part of your body, including your fingers, is in front of the X26 ECD.
  • Shift the safety switch to the up (ARMED) position.
  • Pull the trigger and visually confirm sparking across the electrodes.View the arc from the top or side of the ECD. Do not point the ECD at your face.
  • Shift the safety switch to the down (SAFE) position.

Potential causes of reduced or no effectiveness

  • Loose or Thick Clothing. If the probes lodge in clothing and are too far away from the subject, ECD effectiveness is reduced or prevented.
  • Miss or Single Probe Hit. The current must pass between the probes. If one probe misses, a second cartridge may be deployed if practical and legally justifiable. Using the X26 ECD in the drive-stun mode as described below may also complete the circuit between the single probe and the ECD electrode.
  • Low Nerve or Muscle Mass. If the probes impact in an area where there is very little muscle mass (e.g., the side of the rib cage), the effectiveness can be significantly diminished.
  • Limited Probe Spread. Small probe spreads (including drive-stun) result in little or no effect from NMI and become primarily a pain compliance option.
  • Wires Break. If a wire breaks (e.g., during a struggle), the current will not flow to the probes. Drive-stun is still available.

Drive-stun backup

Drive-stun capability is available with or without a TASER cartridge installed. To apply a drive-stun, place the safety in the up (ARMED) position and pull the trigger. The drive-stun mode generally will not cause NMI and becomes primarily a pain compliance option. Probe deployment is usually considered more desirable, even at close range. Some of the advantages of probe deployment include:

  • Drive-stun is only effective while the CEW is in contact with the subject or the subject’s clothing. As soon as the CEW is moved away, the energy being delivered to the subject stops. Deploying the probes allows the user to separate from the subject while maintaining control.
  • Due to automatic reflex actions, most subjects will struggle to separate from the TASER CEW when it is used in the drive-stun mode. Each time the CEW comes back in contact with the individual, another set of marks may be visible. Using the probes allows for one point of discharge.
  • If the probes are deployed, even at very close range, the user may be able to use drive-stun to another portion of the body that is farther away from the probes, thereby increasing the chance of NMI.

If the drive-stun is not effective, evaluate the location of the drive-stun, consider an additional cycle to a different pressure point, or consider alternative force options.

When using the drive-stun, push (drive) the front of the X26 CEW firmly against the body of the subject. Simply “touching” the X26 CEW against the subject is not sufficient. The subject is likely to recoil and try to get away from the electrodes. It is necessary to aggressively drive the front of the X26 CEW into the subject for maximum effect.

Probe removal and handling used probes


Each agency will establish its own procedure for probe removal, collection, biohazards, evidence collection and maintenance. Treat probes that have penetrated the body as contaminated needles (biohazard). Remember, however, that the probes may also be valuable evidence.

If the probes must be removed from the subject, follow all department policies and procedures, including for handling biohazards.

Below are suggested methods for probe removal.

  • Grab the probe firmly and quickly pull it straight out. Do not twist the probe as the barbed tip may cause additional injury.
  • If the probes are not going to be collected and maintained for evidence, carefully place used probes sharp-tip first into a sharps container, secure in place, and place in a secure location where no one will accidentally touch the probes.
  • Once the subject is restrained, prior to removing the probes, evaluate the need for medical attention as you would with any other use-of-force incident.*
  • Take photos of any injuries, place the photos into evidence.*
  • Collect the expended cartridge, probes, and AFIDs and place them into evidence.*

* As directed by department policy. The TASER training materials provide additional information on forensic evidence collection procedures. The probes, wires AFIDs, and cartridge can yield important forensic evidence if properly collected, maintained, and analyzed.

Effects on animals

The X26 ECDs are an effective option for dealing with aggressive animals and have generally been successful in most deployments. If deployed on a domestic animal, consider having animal control available to restrain the animal.

Note: The aggressive animals are usually incapacitated/stunned momentarily, but recover quickly. The vast majority of the animals quickly left the scene and broke the wires.

Firing Logs

Using the Data Download Kit

Optional download kits are available to permit departments to access the encrypted deployment information in the X26 memory.

The X26 ECD has a highly advanced download function that can help protect a user from claims of excessive use of force by providing documentation of the time and date for each firing. The dataport also provides law enforcement with a powerful management tool to track usage patterns and prevent misuse.

The data download record includes the following information for the last 2,000+ discharges:

  • Date, time, and duration of each discharge in both GMT and local time.
  • Temperature and DPM battery percentage remaining at each discharge.
  • Record of any time changes made to the ECD memory.
  • ECD serial number and current software version.

The X26 download interface uses a USB adapter to connect to any Windows® XP, Windows Vista®, or Windows 7 (32-bit) computer. The simplicity of USB makes using the dataport an easy, fast process. The cable connects to the X26 ECD through the DPM compartment.

The X26 ECD is programmed to Greenwich Mean Time (GMT) at the factory. The conversion to local time, including adjustments to daylight savings time, are all computed in the PC-based software. There is no need to program the weapon to local time or to reprogram the weapon to daylight savings time.

Secure “.x26”data files: The data downloads are saved in encrypted .x26 data files that are more secure than a Word document. This preserves the integrity of X26 dataport download reports for court admissibility.


TASER cartridges overview

Never attempt to open or modify a TASER cartridge. Tampering with a live TASER cartridge could cause it to fire or malfunction (which may result in serious injury). Handle all TASER cartridges with care. Probes may deploy unexpectedly if exposed to physical shock, or static electricity.

TASER cartridges should be kept away from conditions known to create an electrostatic discharge, such as rubbing cloth (e.g., jacket liner or uniform pants) across a cartridge in an environment known to create static shocks.

Cartridge blast doors can be knocked off the front of a cartridge. Because those cartridges cannot be relied upon to consistently discharge, it is recommended that those cartridges be removed from service. Attempting to deploy a cartridge with no blast doors could result in a charge being created and held in the wires. Any conductive material that comes into contact with the front of the cartridge, even after the cycle has ended, could draw the charge to the ignition pin and deploy the probes.


Every time a TASER cartridge is deployed, approximately 20–30 small confetti-like Anti-Felon Identification (AFID) tags are ejected. Cartridges can be assigned to individual users, as each is serialized. Each AFID tag is printed with the corresponding serial number of the cartridge deployed, allowing determination of which user deployed the particular cartridge.

Removing the shipping cover from the cartridge

Cartridges are shipped with a shipping cover in place. Carefully remove these covers before attempting to load a cartridge into the X26 CEW. Be careful to not allow any body part to be in front of the cartridge. Static electricity can discharge a cartridge, and injuries have occurred. A cartridge cannot be loaded into the CEW with the cover in place. Once the cartridge cover is removed, it can be disposed of.

  • Before removing the covers, make sure the front of the cartridge does not point at any body part or at anyone.
  • Carefully place the cartridge with cover face down (blast door down) onto a stable/solid surface, i.e., a table.
  • Place your index and middle fingers onto the sides of the cartridge where the wedges/electrodes are located and place your thumbs onto the locking portions of the cover.
  • Push in with your fingers and pull outward with your thumbs and the cartridge will pop upward, releasing it from the cover.

Note: The cartridge may pop upward quickly when the pressure is released from the locking portions of the cover.

Loading and unloading TASER cartridges

Warning: Never place your hands or fingers in front of the cartridge. This is especially important when loading and unloading the cartridge. Serious injury could result. When loading and unloading always hold the cartridge on the sides or top.

TASER cartridges are shipped with a shipping cover in place. Remove these covers before attempting to load a cartridge into an X26 ECD.


  • Point the ECD in a safe direction.
  • Ensure that the safety switch is in the down (SAFE) position.
  • Make sure the protective shipping cover is removed from the TASER cartridge.
  • Keeping your hand away from the blast doors, place the cartridge (with the cartridge cover removed) into the front of the ECD until an audible click is heard.
  • Verify that the cartridge is secure by pulling on the sides of the cartridge.


  • Point the ECD in a safe direction.
  • Ensure that the safety switch is in the down (SAFE) position.
  • Keeping your hand away from the blast doors, depress the tabs on the sides of the cartridge and remove.

The 15-, 21-, and 25-foot (4.6- , 6.4-, and 7.6-meter, respectively) TASER cartridges are specifically designed so there is no “up” or “down” position – enabling you to quickly reload one in a stressful situation without worrying about putting it in upside down.


X26 maintenance and care

Each agency should establish a maintenance and handling program.

The X26 product is a sensitive electronic piece of equipment, and should be handled with care. Avoid dropping an X26 ECD. Do not use an X26 ECD that has a cracked handle.

  • Check the battery pack regularly. Replace it when the battery percentage reaches 20%.

    Note: The X26 ECD must be stored with the battery pack inserted at all times. Failure to do so may result in loss of time and date settings, software corruption, and/or ECD failure. If the battery pack is left out for an extended period of time, the software in the ECD may be damaged and the date/time may be reset.

  • Check expiration of TASER cartridges (5-year expiration date is listed on the base of the cartridge). Do not use an expired TASER cartridge in the field. Expired cartridges should only be used for training.
  • Occasionally wipe out the cartridge firing bay with a dry cloth. Multiple cartridge firings create carbon build-up (particularly after training courses).
  • Secure in protective holster when not in use.
  • When an X26 ECD is returned to Axon for repair, the download data will be lost. Download the data before returning the unit.
  • Avoid exposing the X26 ECD to excessive moisture, or water.

Dropped or wet X26

If your X26 ECD is dropped or gets wet, follow these instructions:

  • Point the ECD in a safe direction and away from your body.
  • Shift the safety switch to the down (SAFE) position.
  • Safely remove the cartridge.
  • Remove the battery pack.Dry the X26 thoroughly (at least 24 hours). Do not use an external heat source such as a microwave oven or hair dryer to dry the X26 ECD.
  • Reinstall the battery pack.
  • Shift the safety switch to the up (ARMED) position.
    • If the X26 ECD discharges without pulling the trigger, remove the battery pack and return the X26 ECD to Axon immediately.
  • Spark test three full 5-second cycles.
    • If the X26 ECD does not function properly, return it to Axon.
    • If the spark test is normal, return the X26 ECD to service.
  • Shift the safety switch to the down (SAFE) position.

Updating device firmware

The X26 internal software provides functionality for all aspects of the ECD. The software can be upgraded to the most recent version through a DPM or XDPM battery pack, or TASER CAM™ recorder. Each DPM battery pack contains a copy of the weapon software. When the DPM battery pack is first inserted in the X26 ECD, the logic will compare the software version in the weapon with the software version in the DPM. If the DPM battery pack contains a newer version, the software will automatically be uploaded into the X26 ECD. During the uploading, the CID will display a “P.” When uploading is complete, the CID will display the boot-up sequence. The last number in the sequence is the new software version. The programming process takes approximately 10 seconds.

DO NOT remove the DPM battery pack or move the safety switch to the up (ARMED) position during the software programming cycle. This will result in corruption of the data and the X26 ECD will have to be returned to the factory for reprogramming.

You can always install a previous version DPM in the ECD. The software will not program the X26 ECD to an older version and the weapon will remain at the higher of the software versions in the ECD or in the DPM.
