SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing 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 microamperes.).
Leakage current can be measured by any one of three methods.
1. Acommercial 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-operatedAC voltmeter. 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 2 VAC range are suitable. (See
Fig. A)

e life expectancy of the stylus tip is about
500 hours. To preserve good sound quality and

To remove the stylus
1 Turn o and unplug the AC power cords of
the turntable and amplier.
2 Protect the stylus with the stylus cover.

To install the stylus
Do this procedure with the stylus protected by
the stylus cover.
1 Grasp both sides of the stylus holder, then
insert the stylus grip into the cartridge/
headshell receptacle.

Note
Do not push the stylus cover forcefully. Otherwise,
the exposed stylus from the cover may cause injury, or
damage the stylus.
Do not leave any
space.

1 Move the metallic parts inside the
larger gear in the direction of the

around the motor pully.
Aer looping the belt, do not forget to
remove the ribbon.

If this occurs, press STOP to return the tone arm to the
arm stand.
To remove the dust cover
