Notes and Precautions | General Safety Notes 2/2
Before initial start-up
Before putting the hospital bed into operation the first time, the nursing staff must have attended detailed training
in the handling of the bed. In addition, they must be made aware of potential hazards that might occur even when the bed is operated properly.
Moving the bed
Cleaning and disinfection
In order to maintain a consistent functional capability, the clinical bed should be cleaned, disinfected and tested at the soonest possible time following each use, so that it can be reused immediately without risk.
Dangers might occur by improper cleaning/disinfections of the bed.
CAUTION When moving the bed, ensure that the mattress frame is in the lowest position and that the back and leg sections of the mattress frame are completely lowered. Also ensure that the line power cable and power cut-off unit are not dragged along the ground or run over.

A technical check 98 of the bed must be performed at least once per year and after long periods without operation.
If any damage is detected, such as signs of wear and tear, loose bolts and breaks, the damaged portion must be repaired or replaced immediately.

Initial Start-Up | General Operating Instructions
Power-on time
The maximum power-on time for the bed motor unit function is indicated on the bed (identification plate 109) and/ or in the technical data sheet, with the notation "1 min/10 min" meaning that when any bed function has been operated for 1 minute without interruption, the operation must be paused for 10 minutes, in order to protect the motor.
NOTICE If the maximum poweron time of 1 minute is exceeded before the 10 minute waiting period is over, either through separate operations or a longer continuous time period, this can lead to a failure of a motor unit due to safety devices being triggered. The bed will then be shut down for a period of 10 minutes.
Rechargeable batteries
The batteries in the bed have an electric charge capacity that is equivalent to 3 lifting and lying space adjustment operations, with a working load of 210 kg.
NOTICE If the bed is set up at its location without connecting it to the battery charger, energy consumption and self-discharge will lead to the discharge of the battery!
If the battery is totally discharged, it may be sufficiently damaged that early replacement becomes necessary.
In order to achieve a long battery life, proper handling of batteries and the battery charger is absolutely necessary!
To ensure operation of the electrical bed functions at any time, the system should preferably be connected to the line power supply.
Safety device
The bed is provided with an electronic safety device that prevents the drives from being overloaded.

If a beeping sound is heard, the battery pack needs to be recharged. The beep sound becomes weaker the further the battery pack has been discharged. The battery pack will switch off shortly before total discharge. After the bed has been connected to the line power, press any button in the hand control in order to make it fully functional again. The battery pack starts a charging cycle when it is connected to the line power after each use, or when the charge has dropped too low.
NOTICE If the bed is not connected to the line power for a longer period, the battery pack can become discharged. The level of discharge is dependent on the ambient conditions.
NOTICE During the charging cycles, the battery pack is connected to the line power and is thus being supplied with electricity. The LED shows the charging status of the battery pack during the charging cycle. The circuit breaker is disabled, with electric current flowing to the bed.
