Battery compartment lock
To prevent babies and children from swallo-
wing the battery the hearing aid includes a
battery compartment lock. The lock prevents
the compartment from opening. The battery
compartment can only be opened with a spe-
cial key tool. Please see the illustrations for
opening and locking directions.
If the key gets lost the lock can also get un-
locked with the tip of a pen/pencil. Neverthe-
less, we recommend that you contact your
Hearing Aid Professional for a new key tool.
Pre-set controls
Pre-set controls are placed behind the cover
on the back of the device. The cover should
always remain closed to prevent dirt and
moisture from intruding. If the cover gets
lost, contact your Hearing Aid Professional.
The pre-set controls will be adjusted by the
Hearing Aid Professional during your fitting
session. The setting of the controls is done
according to the individual characteristics of
particular hearing loss of the user.
The control settings
should therefore
NOT BE CHANGED
or readjusted
except by your
Hearing Aid
Professional.

Instructions for cleaning
your hearing system
Keep your hearing aid clean. Wipe it off with
a soft cloth or tissue after use and remove
grease and moisture. Remove any accumu-
lated cerumen from the sound outlet, for
example with a small brush. Never rinse
the device in water or other liquids since
this may cause permanent damage to the
electronic. Keep your hearing aid dry. If the
device has been exposed to high humidity
or perspiration, put it in a sealed container
(desiccator) together with a drying agent
overnight. Consult your Hearing Aid Professi-
onal concerning which drying agent to use.
• Do never attempt to dry the hearing aid
with a hair dryer, or in a microwave, etc.
• Protect your hearing aid from rough handling.
• Avoid dropping it on hard surfaces or floors.
• Do not leave the hearing aid near direct
heat or sunlight.
Excessive heat can damage the hearing aid
and even deform the housing.
Ear mould
The ear mould transmits the amplified sound
from the hearing aid into the ear. It is important
that the ear mould fits correctly into the ear
without irritating or hurting the ear. If the ear
mould irritates the ear in any way and prevents
you from wearing the hearing aid, please
contact your Hearing Aid Professional to adjust
the ear mould on the ear. Never attempt to
modify the shape of the ear mould by yourself.
The ear mould should be cleaned every day.
Remove the ear mould and the silicone tubing
from the hearing aid before cleaning the ear
mould. Lukewarm water should be enough
to remove impurities from the ear mould.
Never immerse the ear mould into disinfectant
liquids, such as alcohol since this will damage

with the induction coil in the hearing aid and it
will therefore not operate in the »T« position.
If your telephone is not compatible with the
induction coil, you can still use the hearing aid
with the mode switch set in »M« position. Place
the telephone receiver close to the microphone
of the hearing aid, but not directly on the micro-
phone. If you are in doubt about the compatibi-
lity of telephones in your area, please don‘t hesi-
tate to contact your Hearing Aid Professional.
Induction loop systems
To take advantage of a induction loop system,
move the mode switch either to »MT« or
»T« position. In »MT« position you will be
able to hear both induction loop signal and
microphone signal. If the aid does not work in
»MT« or »T« position the reason can be that
the induction loop system doesn‘t operate.
If the theatre or your church does not have
the tube. If cerumen is stuck in the sound ca-
nal of the ear mould, a syringe with lukewarm
water can easily be used to “wash“ the ceru-
men out. The connecting silicone tube between
ear mould and hearing aid should be changed
if the tubing becomes stiff or brittle. To ensure
that ear mould and tube are in good condition,
please contact your Hearing Aid Professional.
Telephone use
To telephone while wearing your hearing aid
requires some practice. Many hearing aids will
whistle when the phone is near the hearing aid.
To avoid this problem, the VIPER 170P is equip-
ped with an induction coil. By switching the
mode switch to »T« position, the hearing aid will
only receive the sound from the telephone. You
can increase the volume at the volume control
so that the signal is comfortably loud.
Unfortunately not all telephones are compatible

an induction loop system, be as close as
possible to the event. For further information
about the possibilities, please do not hesitate
to contact your Hearing Aid Professional.
Safety precautions
• Consult a doctor if you have foreign
particles in the ear canal, if skin irritation
appears or if excessive cerumen appears
with the use of the hearing aid.
• Different types of radiation, e.g. from MRI or
CT scanners, may damage the hearing aid.
Therefore, do not wear the hearing aid during
these or other scanning procedures. Other
types of radiation (burglary alarms, room
surveillance systems, radio equipment, mobile
telephones, etc) emit low energy and will not
damage the hearing aid. Such radiations only
impact the sound quality or can cause
strange sounds by the hearing aid.
Warning: Do not wear the hearing aid in
mines or other explosive areas, unless those
areas are certified for hearing aid use.
Warning for Hearing Aid Professional:
The device can reach sound pressure levels
above 132 dB SPL! If used without attention
this can cause impairments of hearing!
Service & Repair
If your hearing system does not work, it must
be repaired by a qualified service technician.
Do not try to open the hearing system
casing, as this will void the guarantee and
warranty. Please contact your hearing aid
acoustician/doctor if your hearing system
needs repair.
