If the above information does not answer your questions, please contact Care of Sweden or your local distributor.
Solution
Check that the power adaptor has been connected to the mains supply.
Check that the LED on the power adaptor is showing green.
Check that the power adaptor has not become loose (both the main supply and the control unit).
Check that the switch is set to '1' (On).
If the control unit is warm, the overheating protection may have triggered. If so, wait a while and try
again.
If the problem keeps occurring, contact Care of Sweden or your local distributor.
Restart the control unit. See section 4.9. The control unit will initiate a weighing. Wait for the weighing
symbol to go out and the control unit to go quiet.
Perform a further hand check (see section 4.4). If the gap is still too small, raise the comfort setting in
stages.
If the problem keeps occurring, contact Care of Sweden or your local distributor.
Check that the air mattress is fastened to the bed frame with the straps underneath (two at the head end
and two on each of the long sides).
This is normal if the Alternating program has been selected, as the air supply switches between alternat‐
ing cells for a predetermined cycle period (one cycle = 10–25 minutes).
Check how the control unit is hung on the bed. Resonance can occur, vibrations are felt in parts of the
bed. Remove the control unit and listen to see whether this makes a difference. Can be resolved by put‐
ting the control unit on a flat, steady surface or by placing a towel between the control unit and bed.
If the problem keeps occurring, contact Care of Sweden or your local distributor.
2. Remove the filter from the holder.
3. Place the new filter in the holder with the pink side facing
outwards. Put the protective plate back in place and secure
using the screws.
If the control unit is used in a very dirty environment the
filter should be checked twice a year or more.
7.3 Backup battery
To ensure optimum function and condition, the backup
battery should never be discharged completely. The battery
charges up when the control unit is operating. If the control
unit is left without operating for a long period, the backup
battery should be charged every six months for maintenance
purposes by connecting the power adaptor to the wall socket
and the control unit.
