back on. Again, remember that the monitor
earphones time out – if this happens, press the
Increase and Decrease buttons together and
observe the letters “EA” flashing on the LCD
screen. If you don’t hear sounds, replace the
MicroLink Freedom with the standard Freedom
battery holder and listen to another accessory as
suggested above. If you hear through the alternate
accessory, the MicroLink Freedom may be faulty.
If both the sound processor and the FM system
are working properly individually the next step is
troubleshooting the two systems when interfaced
with one.
If the child complains of noise
, static, or buzzing, see
if y
ou perceive the same through the system, ideall
y
in the classroom where he or she sits.
Move
around the classroom to see if the sound quality
changes. Try a different transmission channel, if you
are using a multi-channel system, making sure that
you synchronize the transmitter and receiver.
If the prob
lems cannot be resolved,
you may want
to contact the child’s implant audiologist, the FM
system manufacturer, or Cochlear Americas.
Nucleus Accessories
Personal audio cable
Enhancing sounds from portable audio
components.
Connect the cable directly to a CD
player, tape player, two-way radio or to any battery-
powered, portable music or gaming system. The
personal audio cable transmits
sound directly to the implant,
improving sound quality. One end
connects to the Nucleus processor
and the other end connects to the
audio component.
The personal audio cable is designed only
for battery-operated components. If a
component is powered by household
electricity, use the TV/HiFi cable.
When using the personal audio cable,
your processor’s microphone will
remain active. To eliminate background
noise, reduce the microphone’s
sensitivity. Reducing the microphone sensitivity
does not affect the level of sound coming through
the cable.
TV/HiFi cable
Connecting the Nucleus processor to an
electricall
y powered TV, stereo, or computer.
A
TV/HiFi cable allows one to connect
the Nucleus implant directly to a TV,
stereo or computer. Simply insert the
cab
le into the headphone jack.
The
TV/HiFi cable can be used with any
battery or 120-v
olt electrical powered
equipment.
When using the TV/HiFi cable, the processor’s
microphone will remain active. To eliminate
background noise, reduce the microphone’s
sensitivity. If a sensitivity MAP is being used,
reducing the microphone sensitivity will not aff
ect
the level of sound coming through the cable.
Telecoil
Delivering greater clarity for listening on the
phone
, to a movie, or to the stereo.
A telecoil
can provide the extra help the child needs to hear
with more clarity and ease in a wide range of
en
vironments. A telecoil is a miniature receiver
that picks up magnetic sound signals from telecoil-
compatible phones and assistive listening systems
(ALS). In many situations, the child may hear this
