The mode setting switch will usually be
on ‘M’ setting.
‘W’ if listening for a very quiet sound in
a quiet environment.
‘T’ setting if being used with a hearing
aid compatible telephone, an induction
loop either in a room or neck loop.
There are two controls on the top of the
processor.
One controls volume or sensitivity.
The other is for switching on and off and
selecting the appropriate program.

The ESPrit 3G consists of the processor and transmitting coil and
cable.
Transmitting coils and cables
NB
If the student has a Nucleus 22 implant (done before 1996), the
transmitting coil has a green connector.
If the student has a Nucleus 24 implant, the transmitting coil has a
yellow connector.
In order to remove the transmitting cable, the battery cover needs to
be removed (see Changing the Batteries below).
Once the cover is removed, attach the plug into the socket as
indicated.
Lay the cable in the channel next to the socket.
Replace the battery cover.
Changing the batteries
To remove the battery cover, grip each side and squeeze. Then pull
the cover down and off.
The three batteries should be replaced at the same time.
The batteries only fit in one way up (with positive side up).
The Magnet
To remove this or to hold it less firmly against the head, turn it anticlockwise.
To replace it or tighten the hold, turn it clockwise.
Do not change the magnet strength without consulting the clinic.
Switching on and off
The processor is switched on and off using the switch next to the
rotary wheel at the top.
There are two program slots available and the implant centre will
advise which one is activated for general use, usually P1.
If the processor is switched on and no sound is heard, it is worth
switching it off again for a few seconds and then trying again.
Rotary wheel control
This can be set to adjust volume or sensitivity, usually sensitivity.
The recommended setting is usually 5 to 6.
Accessories
A number of accessories are available for the 3G. To attach them,
you need to use an accessory adaptor. This plugs into the
accessories adaptor socket at the base of the device next to the
mode switch.

It’s very small and easy to lose!

The personal audio cable, which connects to the accessory adaptor
cable, is used to connect to anything battery powered eg iPod, body
worn radio aid
The TV HiFi cable, which connects to the personal audio cable, is
used to connect to anything powered by the mains eg TV or HiFi.
