Turning the hearing aid on
and off
The battery drawer is used to switch your CIC
hearing aid on and off.
The hearing aid is turned on when a battery is
inserted correctly and the battery drawer is com-
pletely closed.
When the hearing aid is turned on, it will usually
whistle until it is placed correctly in the ear. This
whistling is quite normal, and is caused by an
acoustic feedback loop between the hearing aid
receiver and the microphone. To turn off the hear-
ing aid, you have to open the battery drawer.
Note: When opening the battery drawer, be care-
ful not to force it beyond the upright position.
Please remember to switch the hearing aid off
when it is not in use. Remove the battery if the
hearing aid will not be used again soon.
