Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

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 microamperes.).
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. Follo w 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 A C 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 V A C range are suitable. (See Fig. A)

after another.

Procedure:

1. W hile pressing, the
the ?/1 button to turn on the main power.

2. All segments turn on at the same time, then each segment turns
on press the [A.F.D.] button.

3. To release from this mode, press the ?/1 button or disconnect
the power cord.

[A.F.D.] and [DIMMER] buttons, press

Demonstration Mode

Procedure:

While pressing the [SET UP] button simultaneously, press the

?/1 button to turn on the main power. The set enters the DEMO

mode.
Wait a while, then the demonstration starts. If the ?/1 button is
pressed often the demonstration has started, the power is turned
off, and the demonstration resumes if the ?/1 button is pressed
again.
