Please read the information on the following pages
before using your hearing aid.
A hearing aid will not restore normal hearing and
will not prevent or improve a hearing impairment
resulting from organic conditions. Infrequent use
of a hearing aid does not permit a user to attain full
benefit from it. The use of a hearing aid is only
part of hearing habilitation and may need to be
supplemented by auditory training and instruction
in lipreading.
2.1Hazard warnings
Use only hearing aids that have been specially pro-
grammed for you by your hearing care professional.
Other hearing aids may be ineffective and may, in
certain cases, damage your hearing.
Changes or modifications to the hearing aid that
were not explicitly approved by Phonak are not
permitted. Such changes may damage your ear or
the hearing aid.
2. Important safety information

7
Hearing aid batteries are toxic if they are swallowed!
Keep out of reach of children and pets. If batteries
are swallowed, consult your physician immediately!
If you feel pain in or behind your ear, if it is inflamed,
if skin irritation or accelerated accumulations of
ear wax occur, please check with your hearing care
professional or physician.
In very rare cases, the dome can remain in your ear
canal when removing the hearing tube from the
ear. In the unlikely case that the dome does get stuck
in your ear canal, it is strongly recommended to
see a physician for safe removal.
Hearing programs in the directional microphone
mode reduce background noises. Please be aware
that warning signals or noises coming from behind,
e. g. cars, are partially or entirely suppressed.
The hearing aid contains small parts which can be
swallowed by children.

8
External devices may only be connected if they
have been tested in accordance with corresponding
IECXXXXX standards. Only use accessories approved
by Phonak AG.
2.2 Information on product safety
Your hearing aid is resistant to water, sweat and
dust under the conditions listed in chapter 5. After
exposure to any of these elements the hearing aid
must be rinsed in fresh water and dried.
Protect your hearing aid from heat (never leave it
near a window or in the car.) Never use a microwave
or other heating devices to dry your hearing aid.
Ask your hearing care professional about suitable
drying methods.
When you are not using your hearing aid, leave the
battery compartment open so that any moisture
can evaporate. Make sure that you always completely
dry your hearing aid after use. Store the hearing
aid in a safe, dry and clean place.

Do not drop your hearing aid! Dropping onto a hard
surface can damage your hearing aid.
Always use new batteries for your hearing aid.
You can return used batteries to your hearing care
professional.
Remove the battery if you are not using your hearing
aid for a long period of time.
X-ray radiation (e. g. CT scans, MRI scans) may
adversely affect the correct functioning of your
hearing aids. We recommend that you remove
them before undergoing X-ray procedures and
keep them outside the room.
Do not use your hearing aid in areas where electronic
equipment is prohibited.

The M H2O can be adapted with a variety of
earmolds. On the following pages use the labeled
drawings to identify the earmold that you use.

The following chapter provides step-by-step instructions
on how to use your hearing aid. Please follow
these steps carefully. In the drawings, the parts that
are particularly important for each step are shown
in green.
Step 1. Getting to know your hearing aid
Take the hearing aid in your hand and try out the
hearing aid controls. This will make it easier for you to
feel and operate the controls later on when wearing
the hearing aid.
4. Step-by-step instructions for using
the hearing aid

14
Your hearing care professional can configure your
hearing aid (push) button as either a volume control
or a program selector.
To increase the volume, press the button on your
right hearing aid. To decrease the volume, press the
button on your left hearing aid (Fig. 1a).
In order to change a
hearing program, press
the button displayed

Step 2. Battery preparation
Remove the protective foil from the new battery (Fig. 2).
Wait for two minutes before inserting to activate the
battery.
Step 3. Inserting the battery
Take the hearing aid in your hand (Fig. 3a) and open
the battery door. Insert the battery so that you see the
+ symbol on the battery (Fig. 3b).

Step 4. Turning on the hearing aid
Switch on the hearing aid by closing the battery
compartment (Fig. 4).
Open and close the battery compartment gently
and carefully.
Check if you feel resistance when closing the
battery compartment. Check to make sure the
battery is correctly inserted and in the correct
direction. If the battery is inserted the wrong
way, the hearing aid will not work and the
battery compartment can be damaged.

The hearing aid is now switched on. It can take up
to 15 seconds before it starts. (When you wear the
hearing aid, you will hear an acoustic signal).
Step 5. Inserting the hearing aid
This step shows you how to correctly insert the hearing
aid. The instructions apply for all hearing aid models.
The type of earmold determines how the hearing aid is
inserted.
Each hearing aid is individually programmed for
your right or left ear. For the first step identify
right and left so you will be able to insert your
hearing aid in the correct ear.

Step 5.2 Inserting the hearing aid with classic earmold
With your right hand, take your earmold for the right
ear (red mark on the hearing aid, see step 5.1) between
your thumb and forefinger (Fig. 5b).
Take the earmold up to your ear (Fig. 5b). Place the ear
canal part of the earmold into your ear canal (see the
part circled in green (Fig. 5b)). Next place the hearing
aid behind your ear (Fig. 5c). Then insert the upper part
of the earmold into the upper part of the bowl of your
ear (Fig. 5d).
Fig. 5b Fig. 5dFig. 5c

If you have problems inserting the hearing aid, use
your other hand to gently pull your earlobe downwards.
This opens the ear canal a little more and you can
rotate the earmold until it fits correctly.
Check the fit by running your finger over the bowl of
the ear. You know it fits correctly if, when doing so, you
feel the contour of the bowl of the ear and not the
hearing aid (Fig. 5e). In the beginning, please use a mirror
to check.
You have now successfully inserted the right hearing
aid. Now insert your left hearing aid in the same way
(marked in blue, see step 5.1).
