Congratulations !
As the owner of a new hearing system, you may once again
enjoy the sounds of your environment and conversation
with your family and friends.
These instructions as well as support from your hearing
instrument specialist will help you understand how your new
hearing system works. In this guide, you’ll find instructions
on insertion, removal, and use of your CENTRATM hearing sys-
tem. There are also tips and information on proper handling,
cleaning, care, and changing of the batteries. In addition,
a troubleshooting section is offered for your reference.
Your hearing improvement with a hearing system depends
on the fit of the hearing instruments, the type and degree
of hearing loss, and proper diagnostic testing. Of course, a
hearing system cannot restore normal hearing, and not
everyone will benefit equally.
More than 80 percent of individuals with a hearing loss have
a hearing loss in both ears. Studies show that even when a
hearing loss is worse in one ear, most people with a hearing
loss in both ears will benefit from wearing two hearing
instruments.
Remember, a hearing system consists of finely-tuned devices
that have been specially designed and expertly adjusted for
your individual needs. Proper care and handling will ensure
the best possible performance of your CENTRA hearing
system.

Inserting the battery:
Open the battery compartment with
your fingernail pull the tab on the
battery compartment door outward
until the door swings open all the
way as shown in the illustration.
Battery insertion and removal
Handling the battery
Remove the tab on your battery
only when you are ready to use it.
Three useful tips:
• The positive (+) side of the battery is always the
smooth side. You can recognize the negative (-) side
by the colored ring.
• Always keep spare batteries with you.
• If you think you cannot change the battery by yourself,
ask someone to help you: a family member, friend or
your hearing instrument specialist.
Insert a proper sized battery so
that the "+” symbol on the battery
matches the "+” marked on the
battery compartment.
6
Close the battery compartment by gently pressing the bot-
tom of the door upward with your finger tip. Do not force the
door shut. If it does not close easily, check if the battery was
inserted properly. When the battery door is completely closed,
your hearing instrument is ready for use.
Low battery indicator
Your hearing system may be programmed to inform
you when the battery should be replaced for best system
performance. You may hear an intermittent series of beeps
and/or experience low amplification power or volume.
Change the battery when either of these occurs.
When using a remote control
If you have an ePocketTM remote control, you can check the
battery status using the "data read out” function. (See the
ePocket user guide for more information).

Caution:
Keep batteries and instruments away from the reach of
small children.
Batteries can be harmful if swallowed.
If swallowed consult a physician or a hospital
immediately.
Change the batteries when any of the following occur:
- volume becomes softer or weak
- you hear a battery signal beep
- You see empty battery status on the display of
your ePocket.
Do NOT throw used batteries into household trash.
Return them to your hearing instrument specialist
for environmentally correct disposal.

Inserting and removing your
custom hearing system
Hold the hearing instrument with
your thumb and index finger,
carefully push the instrument in
the ear canal. Gently work it into
its proper position by slightly
twisting until it is firmly seated.
Lightly press inward for a secure
and comfortable fit.
You may find it helpful to pull
your ear slightly upward or to the
back. Once inserted, you should
be able to feel if the hearing ins-
trument is correctly positioned.
Tip:
Practice inserting and removing
your hearing instrument correctly.
An easy way to practice is to sit
down at a table. Place a mirror in
front of you and prop your elbows
on the table so you can guide
your hands easily and safely. This
will help you stay relaxed and
comfortable while you practice.
9
To remove the hearing instrument,
push lightly on the back of your
ear to help loosen it or pull gently
on your ear. Then using your index
finger, slowly pull the hearing
instrument from your ear.
The completely-in-the-canal hea-
ring instruments can be removed
by pulling the small removal cord
toward the back of your head.
Caution:
Never pull on the battery com-
partment door or volume control
wheel to remove the hearing
instrument, as this could cause
damage to your hearing
instrument.

Turning your hearing
system on and off
Via the battery compartment
Your CENTRA hearing system turns on automatically when a
battery is inserted and the compartment door is completely
closed.
To turn the hearing system off, open the compartment
completely.
Via the push button
Your hearing instrument specialist can also program your
hearing system to be turned ON and OFF using the program
button.
To turn your hearing instrument OFF, press and hold the
program button for approximately 2 seconds.
To turn your hearing instrument ON again, press and hold
the program button for approximately 2 seconds.
Please note that when you turn your hearing instrument OFF
using the program button, you must wait approximately 10
seconds for the instrument to reset before you can turn it
back ON again using the program button.
Check with your hearing instrument specialist which ON/OFF
function your hearing system is equipped with
Power-on Delay
Your hearing instrument is equipped with an advanced
"power-on delay" feature. This feature delays sound from
entering your hearing instrument when it is first turned on,
so that you may insert the hearing instrument in to your ear
without experiencing unpleasant feedback (whistling). The
“power-on delay” can be activated by your hearing
instrument specialist.
