HOW IT WORKS…
Sound
comes in via the microphones, is
amplified
by the
hearing aid (
powered by the battery
) and travels through the
hook, tubing and mould into the person’s ear. The hearing aid is
ON
when a battery is in place and the battery compartment is
closed and is
OFF
when the compartment is open (older aids
have a switch: 0 = off and M = on).
IS THE HEARING AID WORKING?
Turn the hearing aid on and cup it between your hands. If your
hearing is OK, you should hear it whistle.
Newer aids usually play a little tune a few seconds after starting
– turn the aid on and hold it near your ear (but not too close!) –
if you hear the tune, the aid is probably working.
WHAT GOES WRONG – WHEN AID DOES NOT WORK AT
ALL – COMMONEST PROBLEMS
NO POWER
No battery
Try a new battery
– batteries last
for 1–2 weeks but
only if the aid is
turned off when
not used.
Battery out
of charge
Try a new battery
–
batteries last
for 1–2 weeks
but only if the aid
is turned off when
not used.
Sticker still
on battery
Remove sticker
or try new
