Battery test
Check the condition of the backup battery by carrying out the
following test.
1. Disconnect the bed from the electricity supply.
2. Raise the mattress platform to maximum height - ignore
the battery warning tone.
3. Raise the backrest and thigh sections as far as they will
go.
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 the
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.
