1.
Check that the AAA battery has sufficient
power (the right battery symbol is not in red).
2. Automatic charging:
• If the main battery is low, the AAA battery in the
smartcavity™ will charge the main battery
automatically. The message “Transferring” is
displayed.
Manual charging:
• Select
Settings
>
Transfer backpower
to start
charging.
• Select
Stop transferring backpower
to stop
charging.
When the main battery voltage reaches 4.0V, the
AAA battery will automatically stop charging the
main battery.
No audible alert or message is given by your
phone if the backpower transfer happens at the
time that your phone is turned off.
Use the AAA battery in time of drained
main battery
If the main battery is drained and your phone
cannot be powered on, you can insert a full capacity
AAA battery into the smartcavity
TM
. It will
automatically charge the main battery and your
phone can be powered on again. The time needed
for charging depends on the remaining power of
the main battery. The lower the voltage, the longer
is takes to wake up the main battery.
Recharging the AAA battery
If you have put a rechargeable AAA battery in the
smartcavity
TM
, you can charge both the main
battery and AAA battery using the AC power
charger(see "Using the AC power" on page 9).
Charging of AAA battery starts after the main
battery is fully charged. If any of the main battery or
rechargeable AAA battery is full, only the other
one will be charged.
Your phone accepts disposable Alkaline,
Lithium batteries and rechargeable Nickel
Metal Hydride (NiMH) batteries. We
recommend that you use Energizer batteries.
Remove the non-rechargeable AAA battery
from the
smartcavity
TM
before you plug the
charger into the AC power socket.
Disconnect your charger from the AC power
after the rechargeable AAA battery is fully
charged.
