Inserting Una In Your Ear - Phonak una User Manual

Preparation
Inserting Una into your ear
If possible, select the mute mode (see page 15) before
insertion, to avoid whistling.
Alternatively, your hearing care professional may
have activated a delayed start-up timer. This function
delays the activation of the hearing system
(for 9 or 15 seconds) after the battery door was closed.
Before insertion, please ensure that you are using the
proper left and right hearing systems. Your hearing
systems are identified as follows:
Blue = left hearing instrument
Red = right hearing instrument
