Each instrument can be identified by its serial
number, located on the outside shell.
Serial Number and Identification
Your hearing instruments are identified by the color
marking of the serial number on the shell of the
instrument. RED is for RIGHT,while BLUE is for LEFT.
IDENTIFICATION
00-00000000

5
Battery Size
Battery sizes can be identified by a color code on
the packaging. Instruments like yours commonly
use either a size 10A battery (yellow marking on the
package), or size 312 battery (brown marking on
the package).
It is very important to use the correct size and type
battery for your hearing instrument.
Because of their size, it’s a
good idea to change and
replace batteries at a table
or desk to reduce the risk of
dropping the instrument
or battery.
BATTERIES
Your hearing instruments use a size _______
battery.
Your batteries have a _________ mark on
the package.

6
To insert or replace
the battery, open the
compartment by placing
your fingernail under the
edge of the swing-out door
and gently pulling outward.
Do not open the battery
door too far or damage is
likely to occur.
Changing Batteries
Remove the old battery by
pushing it out the top of the
fully opened door.
DO NOT pull it out the side
of the door.
Place the new battery in the
compartment with the plus (+) sign facing up.
BATTERIES

7
Close the battery
compartment by swinging
the door until it snaps shut.
NEVER FORCE THE DOOR
SHUT. This could result
in serious damage. If the
door will not close easily,
check that the battery is placed properly in the
compartment and is not upside down.
Low Battery Indicator
Your hearing professional will check the box below
if the low battery indicator for your instruments is
turned on.
When the low battery indicator is turned on, your
hearing instruments will beep four times going from
a high-to-low pitch when the battery’s voltage is low.
Replace the battery when you hear these tones.
BATTERIES
The low battery indicator is turned on.

8
When the battery is too weak to power the hearing
instrument, you will hear a tone for two seconds and
the instrument will shut down. Replace the battery
when this happens.
Battery Caution
Because batteries can vary in size and performance,
your hearing professional is your best source for
lifespan estimates and verification that you are using
the proper size and type.
To help prevent the accidental ingestion of batteries,
keep them out of the reach of children and pets.
Always check your medication before ingesting –
batteries have been mistaken for pills.
BATTERIES
mWARNING:
HEARING INSTRUMENT BATTERIES ARE
DANGEROUS IF SWALLOWED.

Never put batteries in your mouth for any reason,
as they can easily be unintentionally swallowed.
Dispose of used batteries immediately,
using the proper waste or
recycling receptacle.
BATTERIES

10
Before placing your instruments into your ears, make
certain the batteries are inserted properly and the
battery doors are closed securely.
NEVER use the battery compartment door to insert
or remove the instrument! Damage may occur, as the
door is not designed to withstand the pressure.
To insert your instrument, hold it between your
thumb and forefinger with
the volume control toward
the top of your ear. The
battery compartment should
be facing away from your
ear canal.
Note: If your hearing
instrument has directional
microphones, you will insert
the instrument with the
volume control toward the
bottom of your ear.
INSERTION AND REMOVAL

11
Gently push the instrument
in until it is resting
comfortably inside
your canal.
There are two methods
of removing the hearing
instrument from your ear.
One way is by using your
finger to gently massage the
area behind your earlobe.
The soft pressure should
work the instrument out of
your ear.
The other method is to reach
into the ear with the thumb
and forefinger, and gently
pull the instrument out.
INSERTION AND REMOVAL

12
The volume control of your hearing instrument
enables you to turn the instrument “on” and “off,” as
well as adjust the amount of amplification provided
by the instrument.
Your instruments are ready
for use when a functioning
battery is properly placed in
the compartment and the
battery door is closed.
To turn the instrument “on,” use your fingertip to
rotate the volume control forward, toward your face.
You should feel it “click”
on if the instrument was
correctly turned off. To make
sounds louder, continue to
rotate the control forward,
toward your face. Your
hearing instruments may
be programmed to “beep”
when you reach the correct setting.
ON, OFF AND VOLUME CONTROL
ON OR VOLUME
INCREASE

13
To make sounds softer, use
your fingertip to rotate the
control toward the back of
your head.
To turn the instrument “off,”
rotate the control further
backwards, until you feel it
“click” and the control no longer turns.
Some hearing instruments are programmed to have
a power on delay. Your hearing professional will
check the box below if your hearing instruments have
this feature.
The power on delay means that your instruments will
take several seconds to power up once they have
been turned on. This feature allows you to get the
hearing instruments in your ear before they start to
amplify sound.

Multimemory Settings
Your hearing professional will place a check in
the box below if your hearing instruments have a
multimemory push button.
While your hearing instruments make many
adjustments automatically, the multimemory push
button lets you select a different memory setting
for your current listening environment; for example,
when you are using the telephone or sitting in a
noisy restaurant.
When first turned on, your
instruments are most likely
programmed for normal
listening environments.
Additional settings are
accessed by pressing
the button on the
hearing instrument.
OPTIONAL FEATURES
Your hearing instruments have a multimemory
push button.

15
When changing the settings, there may be an audible
beep or indicator to let you know where the memory
is located. For example, the hearing instrument will
beep twice for memory 2. Your hearing professional
will work with you to set the memories to your
preference. With your hearing professional, use the
table below to write in the memory settings for
your instruments.

Your hearing instruments are equipped with
tools to help you effectively communicate on the
telephone. Your hearing professional will check the
box/boxes that represent the telephone settings in
your instruments.
USING THE TELEPHONE
Your hearing instruments have the following
telephone setting(s):
Automatic telephone response
Automatic telecoil
Telecoil. The telecoil is located in memory
position ________.
A beep or indicator tone is enabled on your
instruments to signal you when the device
switches to the telephone setting

17
Automatic Telephone Response and
Automatic Telecoil
These options activate the telephone response
automatically when used with a hearing aid
compatible telephone. To use, place the telephone
receiver on your ear as you normally would and
the hearing instrument will select the telephone
setting. It might be necessary to move the telephone
receiver slightly to find the best reception. Once
the telephone is removed from the ear, the hearing
instrument will switch back to the normal
listening mode.
Note: If you have a hearing aid compatible phone,
but your Automatic Telephone Response or
Automatic Telecoil does not switch to the telephone
setting automatically, your hearing professional can
provide you with a small magnet to place on your
telephone receiver. This magnet will help activate
your automatic telephone option.
USING THE TELEPHONE

18
Telecoil and Manual Switching
Hearing instruments with a
manual telecoil allow you to
switch the devices to telephone
mode when needed.
Manually switched telecoils
are activated by choosing the
telecoil setting using the multimemory button.
General Telephone Use
Some hearing instruments
work best by holding the
phone close to, but not fully
covering your ear. In some
instances, if you encounter
whistling (feedback), tilt the
receiver at an angle until
the whistling stops. Your
hearing professional can give
instructions and techniques
for your specific needs.
