Turning on and off
You have the following options to turn your hearing
instruments on or off.
Via battery compartment:
X
Turning on: Close the battery compartment.
The default volume and hearing program are set.
X
Turning off: Open the battery compartment fully.
When wearing the hearing instruments, an alert tone can
indicate when an instrument is being turned on or off.
When the power-on delay is activated, the hearing
instruments turn on after a delay of several seconds.
During this time you can insert the hearing instruments
into your ears without experiencing unpleasant feedback
whistling.
The "power-on delay" can be activated by your Hearing
Care Professional.
