How does the ‘Hearing Aid Fitting at
Home’ work?

•The hearing aid/s we have posted to you have been set to your most
recent hearing test.
•This means you should be receiving the correct amount of sound from
your hearing aid for your hearing loss.
• When we complete ‘Hearing Aid Fittings in Hospital’ we can make further
adjustments based on how you find the sound, as well as taking into
account the shape of your ears.
• Therefore although your ‘Hearing Aid Fitting at Home’ is accurate, when
we reopen we would like to review your hearing aid settings to check
they are at their complete optimum for you.

How successful is a ‘Hearing Aid
Fitting at Home’?

can lead to serious injury, permanent hearing loss or can even be fatal.
•Always use batteries recommended by your audiologist.
•Never attempt to recharge the batteries.They may explode and cause serious injury.
•Never dispose of the batteries by burning them.
•Keep the batteries clean and dry, and away from extreme heat or cold.
•Keep the hearing aid dry. DO NOT PUT IN WATER TO CLEAN.
•Discard of batteries carefully in a place where children, animals or people at risk of misusing the aids
cannot reach them.

Before we start..
Please be aware of the following safety information and warnings

Further safety information and warnings
•Never put your hearing instrument or batteries in your mouth for any reason, as they are slippery and
could be swallowed by accident.
•Ensure your hands are clean when handling the hearing instrument and its parts.
•Your hearing instrument must never be exposed to extreme heat, for example left inside a parked car in
the sun. They must not be exposed to moisture. Wipe the batteries carefully if moisture is present as it
may affect their performance.
•The chemicals in cosmetics, hairspray, perfume, aftershave, suntan lotion and insect repellent can
damage your hearing instrument. You should always remove the hearing instrument before applying
such products and allow time for the product to dry before refitting your hearing instrument. If you use
lotion, be sure to wipe your hands dry before putting on your hearing instrument.

Lockable Battery Drawers
Are you currently living, or spending a lot of time, with a child below the age of 6
years or are you in close contact with any other individual at risk of gaining access
to the batteries in your hearing aid and swallowing them?
If yes, please do consider asking us for a hearing aid with a lockable battery drawer.
We can order these for you with no effect on the success of the hearing aid fitting.
The only difference between a standard hearing aid and one with the lockable
battery drawer is that you will require a tool to open the drawer (which we will
provide).
If no, proceed with your home hearing aid fitting.

The CROS tube is different as
it does not require sound to
travel through it.
It is there to hold the device in
place over the ear.
The CROS Microphone
picks up sounds and
Bluetooth this to the
hearing aid.
It will not amplify sound to
the ear it is inserted into.

Step 2: How do I tell which ear my
hearing aid is for?
Caring together Learning together Continuously improving Excelling together
If you have two hearing aids, your hearing aids
will have a coloured marker (Red = Right, Blue =
Left) at the bottom of the hearing aid to indicate
which ear it has been set up for.
