No power
If your product is connected to power but does not appear to be receiving power, try the following:
Check the source of power
If using aircraft power, check the aircraft fuse or circuit breaker.
Avoid pressing the power button repeatedly when attempting to turn the headset on or off.
The headset can take up to 6 seconds to turn on or off. Each additional press of the power button will cause the headset to take longer to complete the desired action.
See if the power light is lit on the headset control module.
The LED light on the control module should light when powered on. Press the power button once to turn on the headset, then see if the light is lit. For more info, see Understanding LED indicator status lights and information.
