Replacing the Clock Battery

Replacing the Clock Battery

[NOTICE]

When the clock battery is worn out, the adjusting values, error codes and driving history cannot be backed up (saving data at power OFF). Also, when the error code or driving history is recorded in AML, an accurate date and time cannot be recorded.

Two built-in clock batteries are on CPU board of the AML main unit. Replace both 2 pieces when you replace the battery.

The built-in clock battery longevity is usually about 10 years.

If the built-in clock batteries are worn out, replace them according to the following procedures.

1. Remove the CPU board from the AML main unit.

2. Remove the battery from the battery holder on CPU board by pressing the battery diagonally.

[NOTICE]

When removing the battery, remove while holding the battery upper (positive side) because the battery may pop up.

3. Attach a new battery on the CPU board by pressing the battery diagonally. (Refer to the figure below)

The battery positive side must be faced up.

4. Install the CPU board in the AML main unit.

5. Reconnect the connector to the board.
