How to use jig for the LPS Adjustment (01V32359S01)
TO CONTENTS
Outline
Our JIG is JIG which makes Mechanism Block move to adjust the voltage of LPS for TILT of in-dash monitor such as
“CVA-1004RCVA-1004RR”. It is adjusted with measuring an output voltage from LPS and confirming the voltage.
(This adjustment surely becomes necessary when MONITOR and Mechanism Block are left.)

How to use it (Be sure to carry out this adjustment when you leave DISPLAY and MONITOR 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 using the switch. (Refer to Figure-1.)
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 adjusts it to 0.10+0.10, -0.10V
(the voltage of MONITOR horizontal position). (Refer to Figure-2.)
7. GEAR, LPS ASSY are put after the adjustment.
It confirms that it is 0.01 to 0.20V though voltage value changes a little when it is put.
(Adjustment is necessity again if it comes off 0.01 to 0.20V.)
8. COVER TURNER is put, JIG FLEX. is removed, adjustment completion.
