•When the battery charge level is too low for the phone to operate, the phone displays RECHARGE 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 40).
DISCHARGING BATTERIES
Rechargeable batteries last longer and perform better if allowed to fully discharge occasionally. 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.
