Baha Divino®
The Baha Divino® is a bone conduction sound processor and has a directional
microphone for improved speech understanding in noise. The Baha® bone
conduction system works by combining a sound processor with an abutment and
a small titanium implant placed in the skull behind the ear. The system is based
on a process of osseointegration through which living bone tissue integrates with
titanium. Thus, the titanium implant becomes one with the
bone allowing sound to be conducted via the skull bone directly to the
cochlea and improving your hearing.
The Divino comes in both left and right hand versions (indicated on the sound
processor label) to allow optimal positioning of the directional microphone. It is
essential to use the correct version for the corresponding ear.
Please read this manual carefully to learn how to use and maintain
your sound processor. Be sure to discuss any questions or concerns that
you may have regarding hearing, or use of this system, with your hearing
care professional.

Getting started
Connecting and disconnecting the sound processor
A plastic snap connector is mounted to the sound processor. It is designed to snap
onto the abutment and hold the sound processor securely in place.
Connecting 1 Hold the sound processor so that the plastic snap connector is
accessible and move any hair away from the abutment. Push the sound processor
carefully in with a tilting motion and it will attach to the abutment.
Disconnecting 2 Tilting the sound processor slightly in any direction will
release it from the abutment.
Warning! Do not push the sound processor straight in and do not
pull it straight out. This puts pressure on the abutment and may
cause discomfort.
Note: Do not let the sound processor come into contact with eyeglasses, a hat or
similar items as there is a risk that this will cause feedback (a whistling sound).

Program selector
Use the program selector to get the right setting.
Program 1 Program one uses the omnidirectional microphone so that
the sound processor picks up sound regardless of the direction it comes from.
This program is most suitable for quieter surroundings.
Program 2 In this program setting the directional microphone is activated,
emphasising sound from the front and reducing sound received from the side
and behind. This program is recommended for noisy surroundings as it improves
speech understanding in noise.
For best performance in Program 2 the sound processor should be positioned
vertically with the microphone at the bottom.
Note: A sound processor with the directional microphone switched on reduces
background noise such as the sound of a vehicle approaching from behind.
Warning signals may also be suppressed.
On/Off
Off When the volume control is in the 0 position it is off. You will feel a “click”
as it goes into off mode.
On For the sound processor to be on, the volume control must be set to
a position higher than 0. You will feel a click as the sound processor moves from
off mode to on mode.
Volume control If you turn the volume control upwards the volume increases,
and if you turn it downwards it will decrease.

Care and maintenance
Cleaning the abutment area
When the last dressing has been removed and the abutment is exposed hygiene
continues to be very important.
Daily care
On a daily basis the area around the abutment should be cleaned to avoid
debris build up. This build up around the base of the abutment is not a scab
and must be removed. Cleaning this area is most easily done when you bath or
take a shower as plenty of warm water and soap on the area will help to soften
any crust that may have developed. A soft brush is provided together with your
sound processor for this purpose.
During the first weeks, after the dressing is removed, cleaning with the soft brush
may feel a little rough. If so, use a strip of baby wipe until your skin becomes less
sensitive and you can use the brush comfortably. The soft brush can be used with
any mild soap or shampoo and plenty of warm water.
When you brush, aim the bristles at the side of the abutment rather than at the
skin. Your focus should be to remove crust and debris from around the base of
Tone and AGCo controls
The tone and AGCo controls are to be adjusted by audiologists only.
When fitting the Divino, the audiologist will set the tone and AGCo controls
to suit your needs by increasing or decreasing the low frequency output
and/or compression threshold.
The AGCo ensures a wearer will not be startled by sudden, loud noises and limits
distortion, improving sound quality in loud environments.
Telephones and mobiles
When using telephones, including mobiles, with your Baha Divino®, you
hold the receiver in the normal manner, but close to the microphone inlet
of the sound processor instead of close to your ear. It is important that
neither you, nor the phone, touch the sound processor as this may cause
feedback (whistling).

Maintenance of your Baha Divino
Do not get the sound processor wet. The sound processor can be worn during
waking hours apart from when you take a bath, shower, or swim.
Keep in mind that the sound processor is a delicate electrical device that should
be used with due care and attention. When engaging in physical activities, use
common sense. If the activity is of such a nature that the sound processor risks
getting damaged (for example contact sports) – remove it! If you choose to keep
your sound processor on during physical activity we recommend securing it with
the safety line (see p. 14).
When not using your Baha Divino
When not in use ensure that the sound processor is switched off and stored
carefully where it will not gather dust and dirt. If you will not be using the sound
processor for any length of time, remove the battery. To maintain a good snap
connection to the abutment, we recommend that you use an abutment cover
when not wearing your sound processor.
the abutment rather than brushing your skin. Your skin is delicate and should
not be treated too harshly. Remember, it is important to keep your soft brush
clean too!
After cleaning, gently dry the area around the abutment with a clean towel or
tissue. Do not allow your hair to wrap itself around the abutment. If you use a
hairdryer do not keep the hot air on the abutment for too long.
Weekly care
If you use an abutment cover it will help keep the inside of the abutment clean
however, the inside of the abutment should still be cleaned on a weekly basis.
The soft brush can also be used for cleaning inside the abutment. Again, this
is best done in conjunction with a bath or shower when soap and warm water
can soften dirt making it easy to remove.
Skin debris or any other dirt in the abutment can prevent a smooth fitting of
the abutment to your abutment cover and your Baha sound processor. This
could potentially lead to damage of your Baha device. You will have routine
check-ups initially every 4-6 months and later every 6-12 months.
However, should you experience any persistent irritation, soreness or
any other signs of inflammation around the abutment, always contact
your doctor.

Batteries
Zinc-air batteries type 13 should be used. Please note that these batteries
are not rechargeable.
Battery replacement
Open the battery compartment by releasing the catch on the door, which allows
it to swing outwards. Turn the sound processor over and, if the battery
is stuck, shake the device gently or pull the battery out. Place the new battery in
with the + mark facing upwards and close the cover. If you are unable to slide the
cover back easily, the battery may be incorrectly inserted. Please
check that the + mark is facing upwards.
Warning! The Baha sound processor contains small parts that may
be a risk for small children. Batteries can be harmful if swallowed.
Be sure to keep your batteries out of reach of small children or
people of diminished mental capacity. In the event a battery is
accidentally swallowed, seek immediate medical attention at the
nearest emergency centre.
Attachment of the safety line
If you keep the sound processor on when engaging in physical activities we
advise you to attach a safety line to your sound processor so that it is not lost
if it disconnects. The clip can then be fastened to clothing, for example your shirt
or jacket collar.
We recommend that parents and caregivers attach the safety line to the sound
processors of younger children, to prevent loss and damage.
Cleaning your Baha
Ensure that your snap coupling is always visibly clean. Use a brush for cleaning
purposes. (A regular toothbrush with hard bristles is suitable). Do not use water
or other liquids when cleaning your Baha.
Keep the plastic housing clean by regularly wiping with a soft, dry cloth.
Attention: For children who have been fitted with a Baha sound processor
it is extremely important that the parent or caregiver of the child provides
all necessary assistance and support in cleaning and maintenance, as
detailed above.

General advice
• A sound processor will not restore normal hearing and will not prevent
or improve a hearing impairment resulting from organic conditions.
• Infrequent use of a sound processor does not permit a user to attain full benefit
from it.
• The use of a sound processor is only part of hearing rehabilitation and may need
to be supplemented by auditory training and instructions in lip-reading.
• The Baha Divino is suitable for use in electromagnetic environments with
mains power of typical commercial or hospital quality, and power frequency
magnetic fields of typical commercial or hospital levels. It is intended for use
in an electromagnetic environment in which radiated RF (radio frequency)
disturbances are controlled.
• Interference may occur in the vicinity of equipment the symbol to the right.
• For advice on “do’s and don’ts” for your Baha sound processor see the section on
Warnings and Precautions (p. 21).
Battery life
Battery life begins decreasing as soon as the plastic strip is removed exposing
it to air, even if the battery is not in use.
To maximise battery life, switch off the sound processor when not in use.
Battery life varies depending on volume setting, the sound environment and
the program setting. Battery life will decrease significantly when using the Baha
sound processor with a connected FM receiver if the FM receiver uses the sound
processor as its power source. Using powerful batteries is particularly important
when high current consumption is common. The batteries included with the
sound processor reflect our latest battery recommendation. Battery function can
be related to a number of problems including: no sound, intermittent sound and
crackling/buzzing. Thus, when encountering problems one of the first things one
can do is to try changing the battery.
Note: Always follow local regulations for battery disposal.

Direct audio input and microphone settings
The sound processor has a three-pin DAI (Direct Audio Input) port designed
for connecting external equipment. This can be used in program 1, for
safety reasons you will still be able to hear sounds from your surrounding
environment. In program 2, the DAI is not activated so connected accessories
will be muted.
Note: The marking on the plug must match up with the corresponding
marking on the sound processor.
Safety instructions when connecting external equipment
Only connection cables and accessories that are supplied or approved by
Cochlear should be used. Non-standard connection cables can cause damage
to the sound processor and injury to you. If in doubt, consult your audiologist.
Cochlear is not liable for any damages arising as a result of this, or any other
form of incorrect use of the product or its parts.
Warning! It is extremely dangerous and potentially fatal to connect
any equipment that is plugged into a 110 and/or 220 V power supply
without using the audio adapter.
Accessories
Several accessories are available to enhance your sound experience in
different contexts. To ensure the smooth operation of your Baha, only use
Cochlear original accessories or accessories approved by Cochlear.
