Preset the output level on the FM Standard Signal Generator
to 110dBm.
Observe the waveform of CAMERA IN on WV-PS154 or
WV-PS15 at the Oscilloscope by using the Three Way
Connector.
Adjust the output level on the FM Standard Signal Generator
so that FM Carrier Level of the Video Signal becomes 80mV
as shown in Fig. 3-4.
Note this output level on the FM Standard Signal Generater
as 
A
dBm.

Turn OFF the Power On/Off switch.
Turn the VR100 (for 1-ch) to fully counterclockwise posi-
tion.
Turn on the Power On/Off switch, set the FM Standard
Signal Generator so that the output level becomes 
A
dBm.
Connect the Digital voltmeter to TP100 (for 1-ch) .
Adjust L100 (for 1-ch) so that the DC Voltage on the
Digital Voltmeter becomes 4.3
±
0.1V.
Note : Make sure the unit has sufficiently cooled off
before turning ON the power.
Also, adjust the unit within one minute after turn-
ing ON the power.
Confirm that the DC Voltage is 4.5
±
0.1V at 30 minutes
after turned ON the Power On/Off switch.
For WV-PS154, the same as above, adjust L300 (2-ch) ,
L500 (3-ch) and L700 (4-ch) so that the DC Voltage
becomes 4.3
±
0.1V in similar way of L100 (1-ch).

Set the FM Standard Signal Generator so that the output
level becomes (
A
-21) dBm.
While observing the Audio Output Level, rotate VR101
(for 1-ch) in the counterclockwise direction and adjust
until the Audio Output Level drops a 1dBV range from the
point where it starts to drop.
Change the output level to (
A
-24) dBm from (
A
-21)
dBm.
Confirm that the Audio Output Level is less than 
16dBV.
For WV-PS154, the same as above, adjust VR301 (2-ch) ,
VR501 (3-ch) and VR701 (4-ch) in similar way of VR101 (1-
ch) .
3. Vertical Frequency Adjustment
Test Point : TP106 (V.FREQ)
Main Board
Adjusts :
CT1 (V.FREQ)
Main Board
Note : This adjustment should be done at 10 minutes after
turned ON the Power On/Off Switch.
Connect the Frequency Counter to TP106.
(Ground terminal is TP101 on the Main Board.)
Adjust CT1 so that the Vertical Frequency becomes
204800.000
±
1.024Hz.
2.2. Audio Output Level Adjustment
