4.To charge the battery, simply place the handset on the base. The CHARGE indicator on the base lights.

Charge Indicator

Recharge the battery when the BATT LOW indicator flashes.

Notes:

•If the CHARGE indicator does not light when you place the handset on the base, be sure the battery and AC adapter are correctly and securely connected.

•When you first use the phone after charging or recharging the battery, the phone might not work and you might hear an error tone. If this happens, return the handset to the base for a few seconds.

•If the BATT LOW indicator does not light, but the phone does not work, recharge the battery. (The battery charge might be too low to light the indicator.)

•If the battery pack gets weak dur- ing a call, the handset sounds a beep every 30 seconds, and the BATT LOW indicator flashes. If this happens, you must recharge the battery before you can make another call.

•About once a month, fully dis- charge the battery by keeping the handset off the base until the BATT LOW indicator lights. Other- wise, the battery loses its ability to fully recharge.

•Using a pencil eraser, clean the charging contacts on the handset and the base about once a month to make sure they are not dirty or tarnished.
