26 / Charging the T7406 Battery Pack
Note: Make sure the battery is properly installed in the handset or seated in the charger. If the T7406 battery is not properly installed, or if the battery level is extremely low, the six programmable buttons may light or flash simultaneously. This may also happen when the handset is in the charger.
Exchange the handset battery pack regularly (once a week) if you have a second (spare) battery pack.
The spare battery pack trickle charges in approximately 12 hours. When the spare battery pack is fully charged, the indicator light turns green.
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 24.
