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
