You can recharge the battery (as described in “Charging the Battery” on Page 10) at any time. However, when your phone gives you these low- battery indications, recharge the battery as soon as possible:

When only a few minutes of talk time remain, the phone sounds a warning tone and displays BATTERY LOW at regular intervals.

When the battery charge level is too low for the phone to operate, the phone displays RE- CHARGE BATTERY and sounds a warning tone. The phone automatically turns off about 10 seconds later.

Note: The phone does not sound low battery warn- ing tones if silent service is set to ON (see “Ring Type” on Page 37).

DISCHARGING BATTERIES

Rechargeable batteries last longer and perform better if occasionally allowed to fully discharge. You can do this by leaving the phone on until the phone automatically turns off or you can use the battery discharge feature of any approved acces- sory available for your phone.

Do not try to discharge the battery by any other means.
