SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.
7
LEAKAGE CURRENT CHECK
Q
Q
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

Component Video Level Adjustment
Required measurement equipment etc: Oscilloscope, DVD VIDEO PLAYER (ex: DVD-1500) Test Disc: DVD T-S01
Preparation
(1) Avoid direct blow from an air conditioner or an electric
fan, and adjust the unit at normal room temperature 15 °C ~ 30 °C (59 °F ~ 86 °F).
(2) Playback the color-bar 75% of the Test Disc (Title 12)
using the DVD Video Player, and check that Y and C levels of the S terminal output are within the specified output levels.
TEL 13942296513 QQ 376315150 892498299
If they are out of the specified levels, adjust with the variable resister inside of the unit.
(3) Presetting
POWER (Power source switch) OFFSPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)
DVD (Video terminal) No input
Adjustment
(1) Remove top cover and set VR608, VR609, VR610 on
C-S VIDEO2 Unit at fully counterclockwise (
(2) Connect a pin-plug terminated with 75-ohms to Y(Cb,
Cr) of the Component Video Monitor Output, and hook up the Oscilloscope's probe to both ends of the pin-plug.
(3) Connect S terminal output of the DVD Player with the
DVD input terminal of the Receiver.

(4) Connect power cord to AC Line, and turn power switch
"ON".
