To decrease the volume or sensitivity you must press and
quickly release the toggle switch in the downward direc-
tion for less than one second.
Initial Volume or Sensitivity Settings
When you first attach a PowerCel module to the BTE Sound
Processor, which causes the processor to turn on, the volume is set
to the most comfortable level. This most comfortable level is
established during your programming session. If you prefer to
reduce volume you can toggle the volume down before putting on
your BTE.
The sensitivity is automatically set to the optimum level for every-
day environments. The most comfortable volume level corre-
sponds to the 12:00 position on the volume control and the opti-
mum sensitivity level corresponds to the 12:00 position on the
sensitivity control on the body-worn processor.
Adjusting for Background Noise
In some situations, background noise may interfere with your abil-
ity to hear clearly. Background noise can be particularly distract-
ing in situations where a large number of people are speaking at
once or in a noisy environment. Decreasing the sensitivity on the
BTE Sound Processor may help eliminate some of the background
noise.
Remember that the toggle switch only functions as a sensitivi-
ty control if it has been set to the sensitivity function by your
audiologist during your fitting session.
Using an alternate microphone such as the T-Mic in noisy situa-
tions may also be helpful.
·
To return to previous programs, you must press and hold
the toggle switch in the downward direction for more than
one second.
·
You will notice a brief moment of silence as you change
from one program to the next. The program changes when
you release the switch and it springs back to the mid point.
·
The last position is a reserved for the future implementa-
tion of the microphone test position and is not pro-
grammed to provide stimulation. You will hear silence
when you toggle to this position.
NOTE
: The toggle switch does not have a round-robin capability; i.e.,
when you toggle upward to the last program (or microphone test
position), you must toggle downward to use the first program
again.
Controlling volume or sensitivity:
The toggle switch can function as either a volume or sensitivity
control and is set as one or the other on a program-by-program
basis during your fitting session. Your audiologist will let you
know how the toggle switch function was set for each program on
your BTE Sound Processor.
There are 20 possible steps for volume or sensitivity, 10 in the
upward direction and 10 in the downward direction.
The volume control determines the amount of amplification
applied to the acoustic input. Decreasing the volume will make
sounds softer, while increasing the volume will make sounds loud-
er.
The sensitivity control determines the quietest level of sound that
will be picked up from the environment by the microphone.
Decreasing the sensitivity level makes softer sounds less audible
and may help eliminate background noise. Increasing the sensitivi-
ty level makes softer or more distant sounds more audible.
Increasing/Decreasing Volume or Sensitivity

You can increase the volume or sensitivity by pressing and
quickly releasing the toggle switch in the upward direction
for less than one second.
