Accessories; Changing Batteries; Battery Tips - Cochlear Baha 4 Mode D'emploi

Attaching the safety line
Before connecting the sound processor, attach
the safety line to the sound processor and clip the
other end of the safety line to your shirt or jacket.
Cochlear recommends connecting the safety line
when engaging in physical activities. Children
should use the safety line at all times.

Accessories

Your sound processor can be used with the
Cochlear Wireless Accessories. In addition, your
sound processor has a DAI (Direct Audio Input)
port that is used to connect via a cable directly
to external audio sources, such as MP3 players
(requires the use of the optional Cochlear Baha
Audio adapter), or the Cochlear Baha Telecoil.
Consult your hearing care professional for more
information regarding the available accessories for
your sound processor.

Changing batteries

Use one of the included batteries (zinc-air, non-
rechargeable) as a replacement. The batteries
included in the sound processor kit reflect
Cochlear's latest recommendations. Contact your
hearing care professional for additional batteries.

Battery tips

• Battery life decreases as soon as the battery is
exposed to air (plastic strip is removed).
• Battery life depends on daily usage, volume
setting, use of wireless audio streaming, sound
environment, program setting, and battery
strength.
• To maximize battery life, switch off the sound
processor when not in use.
• If a battery leaks, immediately replace it.
