12 NUCLEUS 7 SOUND PROCESSOR USER GUIDE
Charge rechargeable batteries
There are two chargers that can be used with the
rechargeable battery modules:
• Cochlear Y Battery Charger (see page 14)
• Cochlear USB Battery Charger (see page 16).
Before you start
Your rechargeable battery module has built-in safety and
monitoring features. Read this section before using your
battery charger.
NEW BATTERIES
You need to charge new batteries before first use.
WHAT DO I DO?
• Before using a new battery module, you need to connect it to a
charger until it is fully charged.
CHARGING TEMPERATURE
The battery chargers have a built-in temperature sensor. Batteries
must be charged at 0° C – +40° C (+32° F – +104° F). If battery
module temperature is outside this range, the LED will flash orange
(error).
WHAT DO I DO?
• Charge rechargeable battery modules at a room temperature of
0° C – +40° C (+32° F – +104° F).
BATTERY HEALTH CHECK
Rechargeable battery modules have a built-in “health check”. If a
charged battery detects a problem, it will turn the sound processor
off. If the problem is fixed, it will turn back on again.
WHAT DO I DO?
• If a battery turns off, disconnect and reconnect it to your
processor. If this does not restore power, contact your clinician.
