Change the sidetone volume

Sidetone is the sound that the loopset microphone routes to your hearing aid during a call to help

you hear your own voice.
During a call, press the multifunction key twice, and press a volume key within 15 seconds.

Clear settings or reset your loopset

1. To clear pairing and volume settings, press and hold the multifunction key for more than 8 seconds.

2. To reset, connect the loopset to a charger, and press and hold the multifunction key.
Resetting doesn't clear the settings.
