A conventional high-capacity lead-acid battery can be used for temporary emergency opera-
tion of the electrical drive system. This guarantees that all electric adjustments can be carried
out even during a power cut.
Emergency operation
When the bed is occupied by a patient of normal weight (approx. 80 kg), up to 8 full UP/
DOWN adjustments can be made if the battery is new and fully charged.
Under emergency conditions, if the battery capacity is depleted, a signal tone will sound dur-
ing adjustments.
