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 guidance from your hearing
instrument specialist will help you understand how your new
hearing system works. In this guide, you’ll find instructions
about insertion, removal and use of your CENTRA LifeTM hea-
ring system. 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 refe-
rence.
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 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 Life hearing
system.

Battery insertion and removal
Handling the battery
Remove the tab on you battery
only when you are ready to use it.
Inserting the battery
Open the battery compartment
with your fingernail as shown in
the illustration.
Swivel open the battery compart-
ment door, if not already open.
Place the proper size battery (Type
312) so that the "+” symbol on the
battery coincides with the "+” mar-
ked on the battery compartment.
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 feel you cannot change the battery by yourself,
ask someone to help you: a family member, friend or
your hearing instrument specialist.

6
Close the battery compartment by
gently pressing the bottom of the
door upward with your finger tip.
Do not force the door shut. If
it does not close easily, check to
see if the battery was inserted
properly. When the battery door
is completely closed, your hearing
instrument is ready for use.
Removing the battery
Normally the battery drops out
when the compartment is comple-
tely open. If the battery does not
come out, lightly tap the system or
push the battery out with a pencil
as shown.
Low battery indicator
Your hearing system may be programmed to inform you
when the battery should be replaced for best system perfor-
mance. 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 ePocket remote control, the battery
status can be checked 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.
Power-on-delay
Your CENTRA Life hearing instrument may be equipped with
a “power-on-delay” feature. In this case the hearing system is
automatically turned on with a delay of 12 seconds, so that
you may insert the hearing instrument into your ear without
experiencing unpleasant feedback (whistling).

8
Inserting and removing
your CENTRA Life
Make sure that your hearing
instrument is turned off. Hold
the LifeTip Adapter or earmold
between your thumb and index
finger and insert it carefully into
your ear canal. You may find it
helpful to pull your ear slightly
upward or to the back. Gently
work the LifeTip Adapter with the
LifeTip or earmold into its proper
position by adjusting it until it is
firmly seated in your ear. Once
inserted, you should feel whether
the LifeTip Adapter with the
LifeTip or earmold is placed cor-
rectly. Next, place your hearing
instrument behind your ear and
turn it on.
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.

Turning your CENTRA Life
on and off
To turn off
Press the battery compartment to
the rear down to the first stop to
turn the instrument OFF.
To turn on
Fully close the battery compart-
ment to turn the instrument ON.
Your CENTRA Life hearing system automatically turns on
when a battery is inserted and the compartment door is
closed completely.

e2e wirelessTM
Unique to your CENTRA Life hearing system is the e2e
(ear-to-ear) wireless technology. The wireless functionality...
... automatically adjusts both of your hearing instru-
ments simultaneously to different listening situations
if activated by software.
... allows use of accessories including the ePocket
(bi-directional remote control) function.
... provides synchronization of the settings in the system.
If you change the volume or program on one hearing
instrument, the other is automatically adapted.*
For further information on the ePocket, contact your hearing
instrument specialist or refer to the ePocket user guide. Your
hearing instrument specialist can activate or deactivate the
wireless functionality of your hearing system. The ePocket
can be activated or deactivated separately.
Note:
The performance of the e2e wireless could be affected by
electro-magnetic interference, such as a computer monitor or
halogen lamp systems controlled by a switching power supply.
Move away from the source of interference if you experience
difficulty.
* Change volume and program only with the ePocket.
