Note:
Charge the battery at an ambient temperature in the range from
0°C to 35°C (32°F to 95°F). Depending on the operating conditions of the
device, charging may be interrupted even when the ambient temperature
is lower than 35°C (95°F).
Note:
If the ambient temperature becomes too high during charging, the
Charging LED lights red and charging is interrupted. Charging is
automatically restarted when the ambient temperature becomes
appropriate.
Note:
The battery may not be properly charged at low temperatures
(less than 0°C/32°F) in winter. If this is the case, charge the battery in a
warm room.
Note:
If the device is used as it is just after purchase or after the device
is left without being charged for an extended period of time, the
remaining battery power may not be correctly indicated. Before using
the device, be sure to charge the battery until the LED for Charging turns
green.
Note:
When the device has been connected with the AC adapter or
placed on the cradle, incoming calls do not cause vibration, even with
vibration on.
Note:
As the battery nears a full charge, the LED for charging may turn
green and orange alternately.
