Digital hearing instrument technology
Inside your hearing system, the microphone,
analog-to-digital converter, digital signal
processor, receiver, and other specialized
components process sound that is directed
to the eardrum and auditory system.
The microphone picks up sound waves from the
air and converts them to electrical signals.
The analog-to-digital converter encodes the
electrical signals into a format that is usable
by the digital signal processor, which has been
programmed by your Audiologist or Hearing Care
Provider for your particular hearing loss. The
receiver converts the digitally processed signal
directly back into sound waves.

e2e wireless®
e2e wireless® provides synchronization in
CENTRA hearing instruments. If you are wearing
two hearing instruments and change the
memory or volume on one instrument, the other
is automatically changed. In addition, e2e
wireless technology automatically adjusts
the system to change both hearing instruments
simultaneously to adapt to different listening
situations. The wireless functionality also
enables use of an optional ePocket® remote
control.
Your Audiologist or Hearing Care Provider can
provide more information on the wireless
functionality of your CENTRA hearing system.
Note: The performance of the e2e wireless could be
temporarily affected when in close proximity to
electromagnetic noise sources, such as a computer
monitor or television. Move away from the noise
source if you experience difficulty.
CENTRA S, S VC, and Life BTEs
17
ePocket remote control
An optional ePocket remote control is available
for all CENTRA hearing systems. ePocket can be
used to change the memory and volume of your
hearing instrument, as well as read out the
system settings without having to manually adjust
the hearing instruments.
For further information on the ePocket, speak to
your Audiologist or Hearing Care Provider, or
refer to the ePocket instruction manual, if
applicable.
Changing the memory
CENTRA BTEs may have up to four memories,
also called hearing programs. Each memory is
different and designed to help you hear better in
specific listening situations.
On CENTRA S BTEs, three of the four memories
are selected with the memory button of your
hearing instrument. The fourth memory is
activated automatically when an audio shoe is
attached to the hearing instrument (see "Audio
Input" section).
18
Siemens Hearing Instruments
Additional memories are available on CENTRA S
VC and CENTRA Life BTEs, if you use an
optional ePocket remote control.
When initially turned on (after the battery
compartment door is closed), the microphone
is ON and ready for general use, the default is
Memory 1. Your Audiologist or Hearing Care
Provider will provide you with the number of
memories most appropriate for your needs. Each
time you press the memory button on the
instrument or press the "P" button on the ePocket,
the instrument changes to the next memory. The
memory change may be confirmed by alerting
tones or beeps that correlate to the memory
you are in. That means if you select Memory 3,
then the hearing instrument beeps three times.
If you are wearing two CENTRA hearing
instruments, your Audiologist or Hearing Care
Provider can program them so that the memory
will be changed on both instruments at the same
time when you press the memory button.

Audio Input (CENTRA S and CENTRA S VC only)
Using the directional microphone system
According to your hearing needs, your CENTRA
BTE hearing systems can be adjusted to focus
on sounds in front of you (directional mode), for
when you are having a face-to-face
conversation in a noisy environment. The
hearing system can also be adjusted for when
you are in more quiet environments and want to
hear the sounds around you (omnidirectional).
20
Siemens Hearing Instruments
Your Audiologist or Hearing Care Provider may
program the operation of the directional
microphone system to function automatically, or
in conjunction with the memory button (or
ePocket where applicable), based on your
particular hearing requirements. Consult your
Audiologist or Hearing Care Provider for more
information on use of the directional microphone
system based on the settings of your specific
hearing system.
Volume Control
Your CENTRA hearing instrument is fully
automatic. There is no need to manually adjust
the volume control. However, if you prefer
manual control, your CENTRA S VC BTEs can
be programmed for manual adjustments with
a volume control wheel and/or the ePocket.
Volume on the CENTRA S and CENTRA Life BTEs
can only be programmed for adjustment using
the ePocket.
If your system is programmed for manual
adjustment, the wheel-shaped volume control
on the BTE can be rotated up or down, or the
CENTRA S, S VC, and Life BTEs
21
volume up (+) and down (-) buttons on the
ePocket can be used to select the most desired
listening position (louder or softer).
To increase the volume, place your index finger
gently against the volume control wheel and
rotate it upwards or use the volume up button
on the ePocket. To reduce the volume, rotate the
wheel in the opposite direction or use the volume
down button on the ePocket. Once the maximum
or minimum volume has been reached,
further changes to the volume in that direction
will have no effect.
If you are wearing two hearing instruments, your
Audiologist or Hearing Care Provider can couple
the controls, so that the volume of both will
change at the same time when you adjust either
the volume control wheel or the ePocket.
You may hear soft beeps each time you change
the volume, then a three-beep warning when the
volume limit has been reached. These tones can
be enabled or disabled by your Audiologist or
Hearing Care Provider.
22
Siemens Hearing Instruments
If your hearing instrument has not been
programmed for manual control adjustment,
the volume will adjust automatically and
rotating the volume control wheel or using the
volume control buttons on your ePocket will
have no effect.
Learning volume preference feature
(where provided)
The learning volume preference feature retains
information on when and how you adjust the
volume on your CENTRA instruments
programmed for manual adjustment. Over time,
your CENTRA hearing system will automatically
adjust to that preferred volume in each listening
program. For more information about this
feature, speak with your Audiologist or Hearing
Care Provider.
CENTRA S, S VC, and Life BTEs
23
Audio Input
CENTRA S and CENTRA S VC hearing instruments
are equipped with audio input capability.
This enables you to connect your hearing
instruments to other audio sources such as an
FM system, tape recorder, television, or infrared
system using an audio shoe accessory. It can be
useful for adults in difficult listening situations
and for children in classrooms. Because the
sound is coming directly from the sound source
to the hearing instrument, the signal is clearer
and unaffected by poor room acoustics.

Using the telephone
CENTRA S and CENTRA S VC hearing instruments
are equipped with a T-coil (telecoil) for telephone
use. It may be programmed to work in a specific
listening program in conjunction with the
memory button. In the T-coil mode, place the
telephone receiver close to your hearing
instrument for best reception. By trying
various positions of the telephone receiver, you
will discover what works best for you.
Your Audiologist or Hearing Care Provider can
advise you on the proper use of the T-coil and all
hearing instrument settings.
Note: In order for the telecoil to function properly,
your telephone must be "hearing aid compatible."
Check your telephone’s instruction manual to find
out whether your phone has this capability.
If you are using an ePocket remote control, be sure
to change your listening program out of T-coil mode
before using the "Data Read Out" function. Using the
"Data Read Out" function while in T-coil mode will
cause a loud pulsing noise to be heard, due to
pickup of the transmission signal of the T-coil.
26
Siemens Hearing Instruments
Automatic telephone feature
The AutoPhone® option allows the telecoil in
CENTRA S and CENTRA S VC instruments to
automatically engage when a "hearing aid
compatible" telephone handset is brought close
to the hearing instrument. To operate, bring
the telephone handset close to the hearing
instrument. The telecoil will automatically
engage to the presence of the electromagnetic
signal from the telephone. When you are
finished speaking on the phone, move the
handset away from the hearing instrument and
the microphone mode will reestablish itself.
CENTRA S, S VC, and Life BTEs
27
Cell Phone Compatibility
Some hearing instrument users have reported a
buzzing sound in their hearing instruments when
they are using cell phones, indicating that the
cell phone and hearing instruments may not be
compatible. According to the ANSI C63.19
standard (ANSI C63.19-2006 American National
Standard Methods of Measurement of
Compatibility Between Wireless Communications
Devices and Hearing Aids), the compatibility of a
particular hearing instrument and cell phone can
be predicted by adding the rating for the hearing
instrument immunity to the rating for the cell
phone emissions. For example, the sum of a
hearing instrument rating of 2 (M2/T2) and a
telephone rating of 3 (M3/T3) would result in a
combined rating of 5. Any combined rating that
equals at least 5 would provide “normal use”; a
combined rating of 6 or greater would indicate
“excellent performance.”
28
Siemens Hearing Instruments
The immunity of this hearing instrument is at
least M2/T2. The equipment performance
measurements, categories, and system
classifications are based upon the best
information available but cannot guarantee
that all users will be satisfied.
NOTE: The performance of individual hearing
instruments may vary with individual cell
phones. Therefore, please try this hearing
instrument with your cell phone or, if you are
purchasing a new phone, be sure to try it with
your hearing instrument prior to purchase. For
additional guidance, please ask your cell phone
provider for the booklet entitled "Hearing Aid
Compatibility with Digital Wireless Cell Phones."
CENTRA S, S VC, and Life BTEs
29
AutoPhone magnet accessory
There is an AutoPhone magnet accessory
available for your telephone that can be used
with the AutoPhone feature of your hearing
system. Ask your Audiologist or Hearing Care
Provider about this accessory and if it is
appropriate for your individual hearing care
needs.
Note: When magnets are properly cared for, they are safe to
use and can last a lifetime. However, the following
guidelines should be followed while using these
magnets. Magnets can pose risks to electronics and
magnetic storage media when placed in close
proximity. Be careful not to place magnets near
computers, color monitors, television sets, floppy
disks, video/audio tape, and other electronic
equipment. Magnets may interfere with the operation
of life support systems, such as pacemakers, magnetic
valves, etc. Make certain to maintain a distance of at
least four inches between the magnet and the area of
your support system. Keep magnets out of the reach
of children and pets. If accidentally swallowed, seek
medical attention.
