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 move to a flat, 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. 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 ArjoHuntleigh or an approved
service agent.
To maintain best performance, the backup battery should
be replaced every four years by an approved service
agent.
