The repetition rate of the battery-low warnings depends on
the remaining battery capacity and the battery condition.
The warnings are more frequent when you’re in a call.
Note: If you’ve selected the Vibra Only or Silent Ringing
Option, you won’t hear any warning tones. See “Ringing
Options (Menu 3 1)” on page 37.
When the battery charge is too low for the phone to work,
the phone displays
RECHARGE BATTERY
, then beeps,
then shuts itself off.
Charge the battery as described earlier in this section.
Deep Discharge
If you regularly just ‘top up’ the charge in your battery with-
out ever allowing it to fully discharge first, its life will be
shortened. In order to get the maximum life from your bat-
tery you should allow it to discharge completely about
once a month.
To discharge the battery completely:
1)
Leave the phone switched on until
RECHARGE
BATTERY
appears, then let the phone switch off
automatically.
2)
Leave the phone alone for about 30 minutes (and
do
not
connect a charger within this time) after it
switches itself off.
During this 30 minutes, the phone is in ‘Deep
Discharge’ mode. The way to ‘wake up’ the phone is
to connect it to a charger.
3)
Fully charge the battery after Deep Discharge.
