Backup battery
Caution
To ensure the battery is kept fully charged and prevent damage to
the battery, the bed should be connected to the electricity supply at
all times during normal use.
The battery is intended for emergency short term use only. Its life
will be reduced if it is used to power the bed for long periods.
All functions will remain locked even after mains power is
reconnected. To unlock all functions connect mains power and
then press the Function Lock button twice in quick succession then
select the function(s) to unlock.
746-585-UK-5
The backup battery allows operation of the bed for short
periods when it is disconnected from the electricity supply or in
emergency situations when the electricity supply is not
available.
The battery's charge level is indicated as follows:
If an intermittent warning tone (beep-beep-beep) sounds when
operating the bed, the battery is between 75% and 100%
charged.
In this condition all bed functions remain operational.
If a continuous warning tone sounds when operating the bed,
the battery is between 10% and 75% charged.
In this condition, all functions except CPR and Tilt will be
locked five seconds after the last button is pressed. The other
functions can be temporarily reinstated by pressing the
Function Lock button once and then pressing the required
Function button to unlock its operation.
If the ACP battery indicator lights red, the battery is less than
10% charged.
In this condition, all functions are locked.
