Cautions & Warnings
• CHOKING HAZARD: The sound processor contains small
parts that pose a hazard of inhalation or choking
• If any parts are swallowed consult a physician or hospital
immediately
• Do not allow children to place the battery charger or
battery in the mouth
• Do not chew or swallow batteries. If this occurs, seek
immediate medical attention

3
• Using your sound processor and accessories contradic-
tory to their intended use (e.g. mouthing, chewing) may
cause bodily harm
• Do not expose batteries to excessive heat (e.g. do not
store in direct sunlight or in a hot car)
• Chorus users must not enter a room where an MRI
scanner is located
• Remove your headpiece before connecting to auxiliary
devices
• Only use the battery charger and power supplies provid-
ed by Advanced Bionics to charge Chorus Batteries
• Only use approved wearing options provided with your
system
• Place the sound processor in the protective case before
exposing to liquids, dust or dirt (see protective case
instructions for use)
• The sound processor is only IP68 rated when used in
the protective case with AquaCables and the AquaMic
TM
headpiece. (see protective case instructions for use)
• Remove batteries from your sound processor when they
are discharged to prevent damage from possible leaking
• Do not use broken, frayed, or cracked cables
• Do not expose any part of the sound processor or acces-
sories to extreme heat, such as an oven, microwave, or
hair dryer
• If the sound processor or accessories become unusually
hot, or warm, discontinue use immediately and contact
Advanced Bionics or your cochlear implant professional

4
• In the event of uncomfortably loud sound, discomfort, or
pain remove the headpiece immediately and contact your
cochlear implant professional
• Contact your cochlear implant professional to adjust the
magnet strength of your headpiece if you are concerned
that it is too weak or strong
• Portable and mobile Radio Frequency (RF) communica-
tions equipment, including radios and cellular phones,
may affect sound quality of the sound processor and
accessories; however there is no safety hazard associated
with such equipment
• The sound processor and accessories should be used in
accordance with the electromagnetic compatibility (EMC)
information provided in the ‘Guidance and Manufactur-
er’s Declaration’ section of this Instructions for Use
• The digitally coded, inductive transmission technology
used in this device is extremely reliable and experiences
almost no interference from other devices. It should be
noted, however, that when operating the device near a
computer terminal or other strong electromagnetic fields,
it may be necessary to be at least 60cm (24”) away to
ensure proper operation. If the sound processor does
not respond to the implant because of an unusual field
disturbance, move away from the disturbing field
Intended Use
The Chorus
TM
Sound Processor is a body worn sound
processor that converts sound picked up by the
microphone into electrical signals that are used by
the cochlear implant to enable hearing.

5

Operating Information
The Chorus Sound Processor will only operate with
an Advanced Bionics CLARION 1.0 or 1.2 implant. It
will not operate with any other implant type.
Powering the Chorus
The Chorus Sound Processor is turned on when
a charged Chorus Battery is attached. The sound
processor will always power on in program 1, and with
the volume in the middle position. Sensitivity will start in
the position set for program 1 during fitting. The sound
processor can be turned off by removing the battery.
See also “Power on/off” in the User Controls section of
these instructions.
Attaching and Removing the Battery
To attach the Chorus Battery to the sound processor,
slide it onto the Chorus Sound Processor, as shown
below, until the latch on the battery engages with the
sound processor.
Attach

7
To remove the battery, push the latch downward on
the battery and then slide it away from the sound
processor.
Attaching and detaching the Headpiece Cable
To attach the headpiece cable, push the right angle
connector of the cable into the headpiece cable
connector on the sound processor.
To detach the cable, grasp the connector of the
cable close to the sound processor and pull directly
away and in line with the sound processor. DO NOT
ATTEMPT TO DETACH THE CABLE BY PULLING ON
THE CABLE, OR THE HEADPIECE. DO NOT PULL AT
AN ANGLE.

8
Attaching and detaching the 3.5mm Auxiliary Cable
To attach a 3.5mm auxiliary cable, first ensure you
have a cable with the correct 3.5mm connector, and
then fully push the cable into the 3.5mm connector
on the sound processor.
To detach the cable, grasp the connector close to the
sound processor and pull directly away and in line
with the sound processor. Do not pull at an angle.
The sound processor must be in an Aux Enabled
Program, in order to listen to sound coming from the
auxiliary input. Consult your audiologist and/or fitting
report to verify that you have an Aux Enabled program.
User Controls
Power/Program Button:
Changing Programs: The Chorus Sound Processor
can store up to 3 programs. With the sound processor
powered on, press the power/program button once,
for about 1 second, to advance to the next program.
The sound processor will advance back to program
1, when advancing from the last program in the
sequence (e.g. from program 2 to 1 if 2 programs are
present, or from 3 to 1 if 3 programs are present).

9
Power on/off: To turn the power off using the power/
program button, hold down the button for at least 4
seconds. To turn the power on, press the button until
the LED status indicator illuminates.
NOTE: Turning the power off and then back on always resets the Cho-
rus Sound Processor to program 1, and volume in the middle position.
Sensitivity will start in the position set for program 1 during fitting.
Volume increase/decrease: To increase the volume,
press the ‘+’ symbol on the volume button. To
decrease the volume, press the ‘-’ symbol on the
volume button. There are 10 volume steps up and 10
volume steps down. Consult your cochlear implant
professional if you have any concerns regarding your
volume settings.
Sensitivity increase/decrease: To increase the
sensitivity, press the largest circle on the sensitivity
button. To decrease the sensitivity, press the smallest
circle on the sensitivity button. There are 10 steps up
and 10 steps down. Consult your cochlear implant
professional if you have any concerns regarding your
sensitivity settings.

the sound processor, including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
*Essential performance of the Chorus Sound Processor per
IEC 60601 is defined as auditory stimulation within safe
amplitudes.
RF interference may occur in the vicinity of equipment marked
with the symbol.
The Chorus Sound Processor is intended for use in electro-
magnetic evironments with controlled RF disturbances. Elec-
tromagnetic interference may be prevented by maintaining
distance between portable or mobile RF transmitters and the
Chorus Sound Processor, as recommended.

16
Recommended separation distances between portable and
mobile RF communications equipment and the Chorus
Sound Processor
The recommended separation distance between the Chorus
Sound Processor and an RF transmitter is calculated based
on the maximum RF transmitter output as determined by an
electromagnetic site survey. The following equations are used
to compute the separation distance in meters based on the
transmitter power output in Watts.
