Turn-on precaution
If the hearing aid is turned on again immediately after turning it off,
there may be no sound, but this is not a defect. In such a case,
turn the power off (open battery holder) and wait 10 seconds.
Then turn the power on again (close battery holder).
Removing Hearing Aid
Carefully pull the wire to remove the hearing aid. When acoustic
feedback occurs, open the battery holder (power off). Acoustic
feedback may stop. Then pull the wire first sideways and then
up.
Adjusting the Controls
This hearing aid is a digital type. Any adjustments must be done
at the dealer. For details, please contact the dealer.
Cleaning your Hearing Aid
We recommend that you clean
your hearing aid twice a week
(more or less needed) to remove
any earwax that may build up as
a result of regular use. Too much
earwax build up can prevent your
hearing aid from working.
Hold the hearing aid as the il-
lustration, brush off the earwax
of the sound outlet.
