How do I reset my SupraPlus?
If you are having audio quality issues, such as static, try resetting the system.
To perform a system reset:
Simultaneously press and hold the call control button and the "+" and "-" volume buttons for approximately 5 seconds. When the talk indicator light on the headset blinks, release all buttons.
Press the call control button again. The talk indicator light blinks briefly to indicate the headset is back to normal operation mode.
Disconnect the AC power supply from the base for 5 seconds.
Reconnect the AC power supply. The system reset is complete.
TIP: If you are having linking problems, or you do not hear any audio through your headset, try resubscribing the headset to the base.
