WV-PS154/WV-PS15

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) .

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.

Set the FM Standard Signal Generator so that the output
level becomes 

A

dBm.

Adjust VR102 (for 1-ch) so that the Audio Output Level
becomes 

−

10

±

0.5dBV.

For WV-PS154, the same as above, adjust VR302 (2-ch) ,
VR502 (3-ch) and VR702 (4-ch) so that the Audio Output
Level becomes 

−

10

±

0.5dBV in similar way of VR102 (1-ch) .
