Using theAccessoriesAdaptor Socket
Your Accessories Adaptor plugs into the socket at the base
of your ESPrit™3G.
Figure 4: Accessories Adaptor Socket
When the adaptor is not being used, a socket cover should
be inserted into the socket.
Warning:
Store spare socket covers safely.These small
parts may be hazardous if swallowed or may
cause choking if inhaled.
Using the Mode Settings
To use the particular mode setting, move the mode setting
switch at the base of the ESPrit 3G to the setting
required.

Microphone Setting
The ‘M’ or microphone setting is the normal operating
position, used where there are no specific or adverse
listening conditions.
Whisper Setting
The ‘W’ orWhisper Setting makes soft sounds audible.
In-built Telecoil Setting
The ‘T’ setting activates your ESPrit 3G’s in-built telecoil.
It can be programmed to operate as either a telecoil alone,
or as a mix of telecoil and microphone.
This in-built telecoil allows you to receive signals from a
hearing aid compatible telephone, a room fitted with an
induction loop,or a personal induction loop, such as a neck
loop or cushion loop.The latter are commercially available
devices.
The sound signal from an amplifier,TV or Hi-Fi can also
be conveyed from an induction loop to the telecoil.

Warnings:
Consult your clinician if you wish to change
your magnet arrangement. If the magnet
strength is too weak the coil may fall off. If it
is too strong, it may cause discomfort or skin
irritation.
Store screws, spare magnets and plastic

Batteries
Choosing your Batteries
Your ESPrit 3G uses three high power 675 size hearing-
aid type batteries (button type cells). High Power 675
Zinc Air batteries are recommended.However, in humid
and cold conditions Silver Oxide S76 batteries may be
more reliable.
Use only battery types recommended by your clinician, or
Cochlear. Other types may not have sufficient power to
allow your ESPrit 3G to function properly.

Warning:
Batteries can be harmful if swallowed. Ensure
that batteries are kept out of reach of young
children. If swallowed, seek prompt medical
attention at the nearest emergency centre or
Poisons Information Centre.
Note:
The ESPrit 3G requires three good batteries to
operate. It only takes one bad or substandard
battery to stop the processor from working.When
replacing exhausted batteries, always replace all
three.
High Power 675 Zinc Air batteries are sealed, usually with
a tab.
Figure 14: High Power Zinc Air Batteries
The seal should be removed before use for at least one
minute,to allow for air circulation.
Silver Oxide S76 batteries do not have holes, are not
sealed and so do not require air circulation.Follow the
instructions and warnings for the brand you are using.

16 ♦ESPrit 3G User Guide
Replacing your Batteries
Batteries should be replaced when the low battery
warning ‘beeps’ are heard,or the sound you are hearing
stops, or becomes intermittent. Refer to the Troubleshooting
section for further information.
Immediately remove batteries that do not work. Over a
period of time Zinc Air batteries may leak corrosive fluids.
These can damage your ESPrit 3G.
To change the batteries:
1.Remember to remove their seal and let them stand
for one minute.
2.Turn off the speech processor.
3.Remove the battery cover: slide it down the
ESPrit 3G. See Removing the Battery Cover section.
4.Remove the old batteries by tipping the
ESPrit 3G to one side.They slide out from one side
only.
If the batteries are a little tight, and difficult to
remove, apply a little pressure from the opposite side.
Alternately, use your transmitting coil’s magnet to
draw the batteries out.

5.Using the cleaning brush, regularly clean the battery
area and contacts, to prevent a build up of grime
deposits. Never use abrasive materials or a blade.
6.Slide the new batteries into place.
7.Replace the battery cover by sliding it up from the
bottom until it clips into place.
They only fit when:
· Inserted from the side where the transmitting coil
attaches, and
· When the positive battery terminal (the side with the
holes) faces up.
Note:
Dispose of used batteries in accordance with
your local regulations.
Gently push battery out
from the back
