WARNING
If the battery is left discharged for long periods, its operational life

not use a separate charger or power supply.
The backup battery must be ventilated while recharging. Do not
cover the battery vent hole or obstruct the area around it.

To recharge the battery, connect the bed to the electricity
supply. Allow at least eight hours to recharge the battery when
it is completely discharged.
While the battery is recharging, the ACP battery indicator lights
yellow. The indicator will go out when the battery is fully
charged.
When the bed is disconnected from mains power, it enters a
low power mode to conserve battery power. In this state, the
underbed lights and the indicators on the control panels are
turned off.
Pressing any of the control buttons brings the bed out of low
power mode. The bed will return to low power mode two
minutes after the last control button was pressed.
Continuous operation of the controls may exceed the duty
cycle of the bed's electrical system, causing the indicators
above the buttons to flash. After 30 seconds, the indicators will
light and all functions are locked.
If this happens, wait for at least 18 minutes then follow the
unlocking procedure described in the section "Function
lockout" on page 29.
