Power to the handset comes from the battery pack installed in the back
of the handset. When the battery pack power level is low it must be
recharged in the charging unit.
Low battery
When the power is low, a tone sounds every 15 seconds indicating you
need to recharge the battery soon. Your call is automatically put on hold
20 seconds after the battery pack runs out.
Recharge
Recharging begins as soon as you put the handset in the charging unit.
