AND don’t forget the hearing aid itself...
Just because the hearing aid works on the standard programme
does not mean that it is working on the loop programme (T).
You can do a very basic test by listening to the hearing aid
and moving it near to a piece of electronic equipment with a
mains transformer in it. If you hear buzz near to the
transformer then the loop programme is probably working.
Many hearing aids require the direct input facility to be activated during
programming. Some hearing aids have a protective strip over direct input
contacts and intermittent problems can be caused by a dirty contact plate.
WHEN ALL ELSE FAILS
If nothing appears to be working stay calm! On days
such as these we advise switching to the completely
opposite approach. Instead of testing the overall
system, use the test headphones to just listen to the
fmGenie alone.
Start with as simple a system as possible,
e.g. the internal microphone and an aerial in the
and
just the headphones in the
.
Note: With direct input systems it is necessary to change from
LO to HI
to use the test headphones.
Once you know that the fmGenie system sounds OK, if you
normally use another type of microphone then try that.
If you still cannot get the fmGenie working on its own, try swapping the
or
with another user to identify which unit is faulty, otherwise you will
need to send both units for repair.
If you hear a good sound with the test headphones the fmGenie is
definitely working and the problem must lie elsewhere.
Faults occur more often in accessories than an fmGenie transmitter
or
receiver
.
On the Transmitter
The lapel microphone
Intermittent sound can be caused by an intermittent microphone lead –
check it by trying a spare. A flashing alert indicator and
symbol on the
visual display indicates a faulty microphone lead or aerial.
The aerial
When using an internal microphone a faulty aerial (or no aerial!) causes the
received signal to crackle or break up – check it out by wiggling or trying a
spare, also don’t forget that flashing alert indicator and
symbol indicates
a faulty or missing aerial.
On the Receiver
The neck loop or direct input lead
If you see the sound symbol
flashing on a receiver then the receiver
itself is almost certainly fine so the problem will lie with a broken neck loop
or direct input lead.
Don’t forget the obvious – if no output is present, check that the volume
control hasn’t been turned down and also check that the
symbol shows
when talking on both
and
displays.
Intermittent sound is usually caused by an intermittent neck loop or direct
input lead or shoe – check it out by trying a spare.
David’s tip: if you have a suspect lead loosely tie a knot in it, if it is
confirmed faulty then tie a second knot or bin it!
For both transmitters
and receiver
Batteries
Rechargeable batteries have a life of around 2 years. If rechargeable
batteries appear to not be holding their charge, try recharging them once
more, just in case there was a problem with charging. If they are still not
holding their charge then it is time to replace them with a new set.
If in doubt the battery level can be double checked by pressing the
and
buttons simultaneously to carry out a system reset.
Accessories tester
For those with more than one fm radio system to support,
an fmGenie Radio Aid Accessories Tester is an invaluable
time saver, see page 53.
