POSITION AND PRINCIPLE OF OPERATION
7.5
ELECTRIC EMERGENCY LOWERING VIA THE INTEGRATED 9V BATTERY
The power supply unit fitted (item 8, Overview) on the bed frame is equipped with a 9V block
battery, which makes it possible to make a CPR emergency lowering according to EN 60601-
2-52 in the event of a power failure. Please note, however, that this is only possible once per
9V battery, as the capacity of the 9V battery is limited.
After the emergency lowering has been used once, the 9V battery must be replaced (Type
6LR61 alkaline manganese battery). The 9V battery should however be replaced every 2
years even if it has not been used.
7.5.2
BATTERY CHANGE
To replace, check or remove before lengthy storage of the 9V battery, open the battery
compartment on the power supply unit attached to the backrest motor.
Proceed as follows:
