How to use it (Be sure to carry out this adjustment when you leave DISPLAY andMONITOR Mechanism Block.)

1. It is connected as the above “Connection Figure”.

2. Power supply is turned on. (12V)

3. DISPLAY is moved to the horizontal position by

1) SW1 : The adjustment of TILT is done. (angle adjustment of MONITOR Block)

2) SW2 : The adjustment of Load is done. (The dimension that MONITOR Block comes out is adjusted.)

4. COVER TURNER is removed.

5. GEAR, LPS ASSY (121) are removed.

6. Volume under GEAR, LPS ASSY is turned, and the voltage of the Multi Meter adjust (the voltage of MONITOR horizontal position). (Ref
