Handset Power
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. Refer to “Charging the
T7406 Battery Pack” on page 12 .
