Removing hearing aid
Grasp the pull-out knob and open the battery holder slightly, so
that the hearing aid is set to the OFF condition. Then carefully pull
the hearing aid out of your ear.
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 illustration, brush
off the earwax of the earpiece. Earpiece is
the expendable supplies, replace it with new
one if you can not remove any earwax.
Replacing earpiece
To replace the earpiece, turn the wide section over, and remove
the old earpiece as shown in the illustration. Fit the new earpiece
snugly over the tip of the main unit, return the wide section to the
original position, and rotate several times so that the earpiece is
securely fastened.
Volume Control Adjustment
Before fitting your hearing aid into
your ear, make sure that the Volume
control should be set at the position
of comfortable sound level which you
prefer to hear.
Turning the Volume control
clockwise by an original screw driver
with brush is to put the volume up.
To put the volume down, turn it
counterclockwise. CAUTION!
Make sure that the earpiece must be correctly and tightly attached
to the receiver nozzle. Otherwise, it might fall off in your ear.
