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
lat, 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 Arjo or an approved service
agent.
To maintain best performance, the backup battery should be replaced
every four years by an approved service agent.
