Turn the volume control while lightly pushing it with the ball
of your fi nger.
Removing Hearing Aid
Open the battery holder (power off) and remove the hearing aid
while gently rotating it forward (if not, whistling may result).
4. Adjust the volume control to a suitable level. Turn the control
forward to increase the volume, or backward to decrease
the volume. When the black dots match, the volume is set to
minimum.
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).
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 pre-
vent your hearing aid from working.
Hold the hearing aid as the illustration,
brush off the earwax of the sound
outlet.
