•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 flash 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 cannot make another call on the phone until you recharge the battery.

•About once a month, fully dis- charge the battery by keeping the handset off the base until the BATT LOW indicator flashes. Oth- erwise, 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.
