To clean the Accriva AVOXimeter 1000E Optical Detector, follow these steps:

1. Disconnect the AVOXimeter 1000E from the AC adapter.
2. Use a #0 Phillips screwdriver to remove the four screws from the bottom of the instrument.
3. Hold the upper and lower covers together and place the instrument upright with the keypad to the right.
4. Carefully lift the upper cover while keeping it parallel to the lower part until it is free of the rear panel.
5. Locate and disconnect the battery cable from the J302 connector on the main circuit board.
6. Tilt the upper cover backward to fully expose the main circuit board and small circuit board.

Ensure that these steps are performed only after the AC adapter is completely disconnected from both the instrument and the power source.
