Phonak ComPilot

The Phonak ComPilot is a remote control accessory designed for use with Phonak hearing aids, specifically the audeo model. Unit works but on/off switch doesn't work so will run battery down over week. New battery fitted recently. I got a replacement remote so don't need this and listing in case someone is looking one of these. Update: not sure if unit functions as it doesn't appear to switch on when charging.
