SERVICING NOTE
SAFETY CHECK-OUT |
After correcting the original service problem, perform
the following safety check before releasing the set to the
customer :
Check the antenna terminals, metal trim, ” metallized”
knobs, screws, and all other exposed metal parts for AC
leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth
ground and from all exposed metal parts to any exposed
metal part having a return to chassis, must not exceed
0.5 mA (500 microampers.).
Leakage current can be measured by any one of three
methods. __
1. A commercial leakage tester, such as the Simpson
229 or RCA WT-540A. Follow the manufacturers’
instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for this
job.
3. Measuring the voltage drop across a resistor by
means of a VOM or battery-operated AC volt-
meter. The ”limit” indication is 0.75V, so analog
meters must have an accurate low-voltage scale.
The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOM that is suitable. Nearly
all battery operated digital multimeters that have a
2V AC range are suitable. (See Fig. A)

How to install CAM(A) and CAM(B)
When the CAM(A) and CAM(B) removed or replaced.
Make sure to install these cam’s (marked @ position) with
marked @ position of chassis as show in Fig. 1.

_ TEST MODE
Turned the power on after connect @ pin of IC801 to
ground. (shorted between 1 and 2 pin of TP801).There are
two type of the test can be done as show in below.
1. ALL LED LIGHT
ALL LED will light one second after the power on.
2. HIGH SPEED PLAYBACK MODE
Excutes high speed dubbing when the HIGH SPEED
button is pressed during normal speed mode of DECK-A
or DECK-B.

2. Demagnetize the record/playback head with a head
demagnetizer.
(Head demagnetizer do not approach for the erase
head.)
3. Do not use a magnetized screwdriver for the adjust-
ment.
4. After the adjustments, apply suitable locking com-
pound to the parts adjusted.
5. The adjustments should be performed with the rated
power supply voltage unless otherwise noted.
