NUCLEUS 7 SOUND PROCESSOR USER GUIDE
Charge rechargeable batteries
There are two chargers that can be used with the
rechargeable battery modules:
• Cochlear Nucleus 7 Y Battery Charger (see page 14)
• Cochlear Nucleus 7 USB Battery Charger (see
page 16).
Before you start
Your Nucleus 7 rechargeable battery module has built-in
safety and monitoring features. Read this section before
using your battery charger.
SLEEP MODE
After manufacture, new rechargeable battery modules are put into
“sleep mode” which lasts for up to 2 years. This keeps some power
in the battery, as a completely flat battery won’t charge.
WHAT DO I DO?
Before using a new battery module, you need to
“wake it up” by connecting it to a charger until it is fully charged.
STORING BATTERIES
Your rechargeable battery module will lose some power if you do
not use it for a period of time.
WHAT DO I DO?
Charge your battery module before storing it.
CHARGING TEMPERATURE
Rechargeable battery modules have a built-in temperature sensor.
New batteries must be charged at 0 – 45° C (32 – 113° F). If battery
module temperature is outside this range, the LED will flash orange
(error).
WHAT DO I DO?
Charge new rechargeable battery modules at a
room temperature of 0 – 45° C (32 – 113° F).
