How to look after your Baha®System
– and yourself!
Your Baha®sound processor is part of a sophisticated hearing
system full of delicate microelectronic components, so you
must take care of it – and yourself!
This brochure shows you what to do after the surgery and how to keep
your Baha sound processor and the abutment site in prime condition. The
procedures outlined both here and in the accompanying DVD are so easy to
follow, that they’ll soon become part of your daily routine.
And the rewards will be well worth the effort! With a Baha system you’ll be
able to hear and communicate with ease.

After surgery
For the best result, you need to take care of the abutment to avoid
any complications with the surrounding tissue. If the area has healed,
the dressing and stitches will be removed 10–14 days after surgery. If
not, the dressing may have to stay in place longer.
At home it is important to maintain good daily hygiene; for the
first few weeks after the dressing has been removed, wash your hair
carefully and use a strip of abutment cleaning wipe to keep the skin
around the abutment clean.
Daily cleaning
After the first few weeks you can start cleaning the outside of the
abutment with the soft abutment cleaning brush provided. Aim the
bristles at the side of the abutment, and remove any debris that might
have built up around the base. You can do this while taking a bath or
shower, using mild soap and plenty of warm water. When you have
finished bathing, use a strip of abutment cleaning wipe to make sure
that all debris has been removed.

7
Weekly cleaning
Clean the inside of the abutment every week, with the abutment
cleaning brush, as debris can also build up there.
If you should experience soreness or inflammation, or if the abutment
feels loose, contact your clinician or hearing care centre. Otherwise,
it’s a good idea to get regular checkups every six months.
Remember:
• Always rinse the abutment
cleaning brush in mild soap
and warm water and let it
air dry. Change the brush
every three months, or if
you have had an infection.
• If you have bilateral
implants, use two separate
cleaning brushes (one for
each abutment), to avoid
cross-contamination.
• You can get new cleaning
brushes from your hearing
care centre or by contacting
your Cochlear™office.

8
Attaching and removing
your sound processor
Your Baha sound processor is designed to snap onto the abutment.
Simply attach it at a slight angle and tilt or rock it into place, taking
care to keep your hair out of the way. The tilt technique reduces the
pressure on the abutment and prevents any discomfort. Make sure
you never push the sound processor straight in.
To remove the sound processor again, lift your hair, slide a fingertip
under it, and gently tilt it until it snaps off. Never pull it straight out.

9
Protecting your abutment
Whenever you are not wearing your Baha sound processor, you can
shield the abutment using the press-on abutment cover provided with
your sound processor. Wear it when sleeping, and when having hair
treatments. During rough contact sports you can wear a sweatband
over the abutment for additional protection.
Attaching a safety line
When taking part in activities where you risk losing your sound
processor we recommend using the safety line provided. Insert the
line into the attachment point and fasten it to your clothing.
Note: The safety line should always be used when a Baha sound
processor is worn by children.

10
Baha and children
Children who use a Baha system need to observe the same routines
as adults. Their parents/caregivers should teach them how to keep the
abutment clean and the skin around it healthy. They should also be
taught the importance of keeping their Baha sound processor safe –
including using a safety line to avoid losing it.
Note: In the United States and Canada, the placement of a bone-
anchored implant is contraindicated in children below the age of 5.
What is a Baha Softband?
Until children are ready for an implant they can wear their Baha sound
processor on a colourful Baha Softband. This consists of an elastic
headband with a plastic snap connector that holds the sound processor
in place. To avoid any sore areas, this adjustable band can be turned,
so the sound processor is not always in the same position. The Baha
Softband enables a variety of listening opportunities. For example, in a
car seat the sound processor can be worn on the forehead to maximise
sound perception.

Twelve golden rules
for handling your Baha sound processor
Your Baha sound processor contains very delicate components, so
you should handle it with care – and never drop it! Follow these
golden rules to keep your sound processor safe:
12
1. You can wear your Baha sound processor
all day long – apart from when sleeping, bathing,
showering, swimming or during rough contact
sports.
2. When adjusting your sound processor, make
sure your hands are clean to avoid getting the
inside or outside of the casing dirty.
3. When taking part in activities where you
could lose your sound processor, either remove it
or use the safety line provided.
4. Your Baha sound processor is NOT
waterproof. Never wear it in the shower or when
swimming. In rainy conditions, use an umbrella.
5. If visiting or living in an area with high
humidity, you can use a Dry Aid Kit (a bag or
container that contains crystals that absorb residual
moisture from your sound processor) to keep your
sound processor in good working order.
6. Your Baha sound processor cannot withstand
extreme temperatures. So never leave it on the
dashboard in your car in bright sunlight or expose it to
any other kind of extreme treatment.

7. Clean the external casing of your sound
processor regularly with a Sound processor
cleaning wipe, and clean the snap with a small
sound processor brush (both provided in the
Aftercare Kit).
8. When using hair products like hairspray,
always cover your Baha sound processor to
avoid damaging the microphone or the casing.
Alternatively, remove it entirely.
9. To avoid feedback (whistling), don’t let
objects come too close to your Baha sound
processor (e.g. a hat, hairbrush, phone, glasses etc.).
10. To store your Baha sound processor safely
after use, remove the battery and place the sound
processor in its case.
11. If you need an MRI scan, it is crucial to
remove the sound processor beforehand. The
implant and abutment can remain in place.*
12. When travelling, remove your Baha sound
processor when going through security screening
to avoid setting off metal detectors in places such
as airports. An MRI/Security control instructions
card is included with your sound processor, which
provides information for airport personnel.

Using phones and other accessories
The best way to use telephones and cell phones with your
Baha sound processor is to hold the phone receiver close to the
microphone inlet of your sound processor rather than close to your
ear. Don’t let your hand or the phone touch the sound processor, as
this may cause it to whistle. When using Baha Cordelle II, the phone
receiver should be next to the microphone on the body-worn unit.
Most landline telephones are “hearing aid compatible” i.e. they have
a built-in telecoil. If you are a Baha 3 System, Baha Divino or Baha
Intenso user, you will need to attach the Baha Telecoil accessory
to your sound processor and switch to the program for external
equipment. For Baha Cordelle II, the telecoil is built into the body-
worn unit, so all you need to do is switch to the Telecoil program.
Telecoils, FM receivers, and Audio adapters are available as optional
accessories for your sound processor. They are easy to order from
your hearing care centre or your local Cochlear office.
Note: FM receivers should be ordered from a hearing care centre or
the FM system manufacturer directly.

15
FM Receivers
An FM system makes listening easier in noisy environments,
such as in classrooms. FM receivers can be specific in how they
connect to your Baha sound processor; consult a hearing care
specialist to determine the FM receiver that is best for you.
Telecoil
The Baha Telecoil accessory may help you hear better when using a
phone or in buildings with loop facilities, such as churches, theatres,
and airports. The Baha Cordelle II has a built-in telecoil, so no external
accessory is required.
Audio adapter
The Audio adapter allows direct input from computers, personal
stereos, TVs, MP3 players and other external equipment. Always use
the audio adapter to connect your Baha sound processor to any
electrical or battery-operated equipment.
Only Cochlear products and accessories, or products and accessories approved by Cochlear, should be
used with each other to ensure the warranty is maintained.
*Choice of accessories may vary depending on your Baha sound processor model
