1) Supply power to the main unit, using the variable-voltage DC power supply (range of 2.5V to 5V).
2) Set the CAM/OFF/VCR SW to CAM to switch to the camera mode.
3) Load a recordable tape and set the main unit to CAM REC. PAUSE.
4) Set the main unit to TEST mode No. 3, and start recording.
5) Measure voltage between TL901(+) and TL903(GND), and adjust the supply voltage to 3.0V.
6) The adjustment is complete if "BATTERY" is displayed on the monitor screen for a second when the PLAY key of
operation unit is pressed.
7) The adjustment is regarded as proper if the auto shut-off is actuated after the warning is displayed when the TEST mode
is cancelled.
