Performing a function test

ARC Switch-Initiated Function test

Axon Enterprise recommends conducting a function test prior to the start of your shift. The function
test is done to verify that the CEW’s core electronics are working properly. To test the trigger, see
Trigger-Initiated Function Test.
An X2 CEW can be function tested with the cartridges loaded. In fact, it is recommended you perform
the test with cartridges installed to reduce stress on the CEW’s components.
To perform a function test:

  1. Point the CEW in a safe direction.
  2. Place the top rail of the X2 CEW in the palm of your secondary hand so you can grip the top rail and your thumb can reach the ARC switch, while the remainder of your secondary hand and fingers are away from the front of the CEW.
  3. Shift the safety switch to the up (ARMED) position. Keep all fingers away from the trigger and keep the CEW pointed in a safe direction. While performing a spark test, DO NOT touch the trigger at any time.
  4. Press and hold the ARC switch for five seconds. Verify the arc rides across the face of all loaded
    cartridges between the arc deflector metalized labels.

    Use the ARC switch, not the trigger, to perform a spark test. Pulling the trigger switch will deploy a loaded unfired cartridge.

    View the arc from the top or side of the CEW. Do not point the CEW at your face or have it near your face.

  5. Look at the CID display and verify the following:
    • No critical or major fault icons display on the upper-right corner of the CID.
    • The cartridge information matches the cartridges inserted in the X2 firing bays.
    • LO BATT is not displaying on the CID.

    If any of the above verifications fail, return the unit to your agency’s CEW technician for service.

  6. Shift the safety switch to the down (SAFE) position.

Trigger-Initiated Function Test

The function test above only checks the functionality of the core electronics. It does not check the functionality of the trigger or the CEW’s ability to deploy cartridges. If you wish to perform a trigger
function test, this procedure is recommended:


Note: Use inert resettable simulator cartridges, which have clear or red blast doors, for this test. Inert
resettable simulator cartridges do not have probes.


Do not use live Smart Cartridges (that have black blast doors), or training simulator cartridges
(that have blue or purple blast doors) for this test.

  1. Ensure the safety switch is in the down (SAFE) position.
    Ensure the CEW is loaded with inert resettable simulator cartridges. As necessary, see Loading and Unloading Smart Cartridges for more information.
  2. Point the X2 CEW in a safe direction that allows you to see the arc in the cartridge bays. Do not
    point the CEW at your face or have it near your face.
  3. Shift the safety switch to the up (ARMED) position.
  4. Pull the trigger.
  5. Allow the X2 CEW to complete the 5-second discharge duration and visually confirm the arc
    across the cartridge in bay #1.
    View the arc from the top or side of the CEW. Do not point the CEW at your face or have
    it near your face.
  6. Pull the trigger.
  7. Allow the X2 CEW to complete the 5-second discharge duration and visually confirm the arc
    across the cartridge in bay #2.
  8. Confirm that the CID shows the cartridges as being deployed and that no errors have occurred
    during the simulated firings.
  9. Shift the safety switch to the down (SAFE) position.
  10. Unload the inert resettable simulator cartridges.
  11. Reload live cartridges if appropriate to do so.
