SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Checkthe antennaterminals,metal trim,“metallized” knobs,screws,
and all other exposed metal parts forAC 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 voltmeter. The “limit” indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2 VAC range are suit-
able. (See Fig. A)

US
You can use the remote RM-PG411 (STR-
DE985 only) or RM-PP411 (STR-DE885 only)
to operate the components in your system.
Before you use your
remote
Inserting batteries into the
remote
Insert R6 (size-AA) batteries with the + and –
properly oriented in the battery compartment.
When using the remote, point it at the remote
sensor on the receiver.
Tip
Under normal conditions, the batteries should last for
about 6 months. When the remote no longer operates
the receiver, replace all batteries with new ones.
Notes
•Do not leave the remote in an extremely hot or
humid place.
•Do not use a new battery with an old one.
•Do not expose the remote sensor to direct sunlight
or lighting apparatuses. Doing so may cause a
malfunction.
•If you don’t use the remote for an extended period
of time, remove the batteries to avoid possible
damage from battery leakage and corrosion.
