Testing

Axon Signal Vehicle is thoroughly tested prior to shipment. However, should an issue be encountered during installation or during the life of the product, follow these steps to troubleshoot.

  1. Verify Axon Signal Vehicle has power and turn on the ignition or alternate enabling source.
  2. Monitor the diagnostic LED indicators:
    • A green Power LED indicates Axon Signal Vehicle is powered up.
    • A green Status LED indicates a successful start-up.
      • If both lights are illuminated, Axon Signal Vehicle is ready and working properly.
      • If neither light is on, use a voltmeter to verify voltage at the system power input J2-1 and the enabling source(s) J2-3 and/or J2-4.
      • If only the Status LED is not illuminated, turn off Axon Signal Vehicle by removing the enabling signal (ignition or auxiliary). Verify the Power LED turns off when this action is performed. Reactivate the enabling signal and allow the system to boot for a few seconds. If this does not cause the Status LED to turn on, cycle power for Axon Signal Vehicle by disconnecting system power at J2-1 and reconnecting it.
      • If either light remains off, contact Axon Technical Support.
  3. Turn on the trigger (for example, activate the vehicle’s light bar).
  4. Verify the Status LED is blinking (requires firmware version 4.2.1 or later for this functionality).
  5. Listen for the two beeps that indicate the Axon camera system now is in EVENT (recording) mode. If you do not hear the beeps:
    • The camera may not be enabled for Axon Signal activation. See the Evidence.com User and Administrator Guide for information on Signal configuration and Axon Body Camera settings for use with Axon Signal products.
    • The camera might be in stealth mode. See the Fleet camera’s user manual for instructions on deactivating stealth mode.
