3.3 Battery Test
Check the condition of the backup battery by carrying out the following test.
1.
Disconnect the bed from the mains electricity supply.
2.
Raise the mattress platform to maximum height.
3.
Raise the backrest and thigh sections to maximum elevation.
4.
Press and hold the CPR button. The mattress platform will
flatten and lower to a mid-height position.
5.
Lower the mattress platform to minimum height.
6.
Apply maximum head down tilt (Trendelenburg).
7.
Return the mattress platform to the level position, then
apply maximum foot down tilt (reverse Trendelenburg).
If this test is not completed successfully, connect the bed to mains electricity supply for at
least eight hours to recharge the battery, then perform the test again. If the bed fails a
second time, contact Arjo or an approved service agent.
To maintain best performance, the backup battery should be replaced every four years by
an approved service agent.
CAUTION
If the bed is stored for a long period of time, it should be connected to the
electricity supply for 24 hours every three months to fully recharge the backup
battery, otherwise it may become unserviceable.
