SAFETY
CHECK-OUT
(US
Model)
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 0.5mA (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 instru-
ments.
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 0.75 V, 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)

Ground pin
Speed output
This pin outputs ‘L’’ in 33 rpm and
"H'’ in 45 rpm.
Turntable roatation output
Turntable roatates when this pin outputs
“H'" it stops when this pin outputs “L"’.
Pause cancel signal output
Record muting signal input
Reset pin
When this pin inputs ‘L’’ -+’'H"’, reset
function operates.
Size detect input
This pin detects that there is nor record
when 4 pulses are input, there is a 17cm
record when 2 pulses are input and there
is a 30cm record when no pulse is input
during roatation of turntable. The size
is detected by trailing-edge portion of
pulse.
Solenoid (PM102) output
When this pin outputs ’’H’’, PM102 goes
ON.
Solenoid (PM101) output
When this pin outputs ‘'H’’, PM101 goes
