SAFETY PRECAUTIONS

1. Before returning the instrument to the customer, always
make a safety check of the entire instrument, including, but not
limited to, the following items:

a. Be sure that no built-in protective devices are defective and/

or have been defeated during servicing. (1) Protective
shields are provided on this instrument to protect both the
technician and the customer. Correctly replace all missing
protective shields, including any removed for servicing
convenience. (2) When reassembling the instrument, be
sure to put back in place all protective devices, including, but
not limited to, nonmetallic control knobs, insulating fishpapers,
adjustment and compartment covers/shields, and isolation
resistor/capacitor networks. Do not operate this instrument

or permit it to be operated without all protective devices
correctly installed and functioning. Servicers who defeat
safety features or fail to perform safety checks may be
liable for any resulting damage, and may expose
themselves and others to possible injury.

b. Be sure that there are no cabinet openings through which an

adult or child might be able to insert their fingers and contact
a hazardous voltage. Such openings include, but are not
limited to, (1) excessively wide cabinet ventilation slots, and
(2) improperly fitted and/or incorrectly secured cabinet covers.

c. Leakage Cold Check - With the instrument AC plug removed

from any AC source, connect an electrical jumper across the
two AC plug prongs. Place the instrument AC switch in the
on position. Connect one lead of an ohmmeter to the AC plug
prongs tied together and touch the other ohmmeter lead in
turn to each push button/customer control, exposed metal
screws, metallized overlays and to each cable connector. If
the measured resistance is less than 1.0 megohm or greater
than 5.2 megohm an abnormality exists that must be corrected
before the instrument is returned to the customer. Repeat
this test with the AC switch in the off position.

d. Leakage Current Hot Check

On completely assembled instrument, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation
transformer during this test.) Use a leakage current tester or
a metering system that complies with American National
Standards Institute (ANSI) C101.1 Leakage Current for

Appliances and Underwriters Laboratories (UL) 1492 (Section

67). Measure for current from a known earth ground (metal

waterpipe, conduit, etc.) to all exposed metal or conductive
parts of the instrument (antenna connections, handle bracket,
metal cabinet, screwheads, metallic overlays, push-buttons,
control shafts, etc.), especially any exposed metal parts that
offer an electrical return path to the chassis. Any current
measured must not exceed 0.5 milliamp. Reverse the
instrument power cord plug in the outlet and repeat the test.

ANY MEASUREMENTS NOT WITHIN THE LIMITS
SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK
HAZARD THAT MUST BE ELIMINATED BEFORE
RETURNING THE INSTRUMENT TO THE CUSTOMER OR
BEFORE CONNECTING TO ANTENNA OR
ACCESSORIES.

e. Interconnected Equipment AC Leakage Test

Avoid shock hazards. The instrument, accessory, or cable(s)
to which this instrument is connected should have the
applicable sections of the leakage resistance cold check and
the leakage current hot check performed. Do not connect
this instrument to an antenna, cable or accessory that
exhibits excessive leakage currents.

2. Read and comply with all caution and safety-related notes on or
inside the instrument cabinet, and on the chassis.

3. Design Alteration Warning - Do not alter or add to the mechanical
or electrical design of this instrument. Design alterations and
additions, including, but not limited to, circuit modifications and
the addition of items such as auxiliary audio output connections,
cables and accessories, etc., might alter the safety characteristics
of this instrument and create a hazard to the user. Any design
alterations or additions will void the manufacturer's warranty and
will make you, the servicer responsible for personal injury or
property damage resulting therefrom.

4. Observe original lead dress. Take extra care to assure correct
lead dress in the following areas: (a) near sharp edges, (b) near
thermally hot parts - be sure that leads and components do not
touch thermally hot parts, and (c) the AC supply. Always inspect
in all areas for pinched, out-of-place, or frayed wiring. Do not
change spacing between components and the printed-circuit
board. Check AC power cord for damage.

5. Components, parts and/or wiring that appear to have overheated
or are otherwise damaged should be replaced with components,
parts or wiring that meet original specifications. Additionally,
determine the cause of overheating and/or damage and, if
necessary, take corrective action to remove any potential safety
hazard.

6. PRODUCT SAFETY NOTICE - Many electrical and mechanical
parts have special safety-related characteristics, some of which
are often not evident from visual inspection, nor can the protection
they give be obtained by replacing them with components rated
for higher voltage, wattage, etc. Parts that have special safety
characteristics are identified in this service data by a ( ! ) on
schematics and in the parts list. Use of a substitute replacement
that does not have the same safety characteristics as the
recommended replacement part in this service data parts list
might create shock, fire and/or other hazards. Product Safety is
under review continuously and new instructions are issued
whenever appropriate. For the latest information, always consult
the appropriate current service literature.

BEFORE REPLACING PARTS, READ THE FOLLOWING:
Approved Substitute Stock Numbers - Before ordering stock numbers

in the part list, look for an approved substitute stock number in the
current Price Schedule. This will minimize your service time and
avoid ordering parts you already have in stock.

PRODUCT SAFETY NOTE: Components marked with a critical
safety symbol have special characteristics important to safety.
Before replacing any of these components, carefully read the
PRODUCT SAFETY NOTICE in the basic service data. Do not
degrade the safety of the set through improper servicing. Although
assemblies as a whole may not be marked with a critical safety
symbol , replacement of assemblies with other assemblies not
approved may result in a safety hazard.

Critical Safety Symbol
Not Eligible For Warranty

@NOTE: When ordering components that are listed more than once in this part list, always adhere to the serial number application guidelines
given in the description column. If a serial number application guideline is not given, always select the component with a value, rating, other
specification or identification marking(s) that match those of the corresponding component in the instrument you are servicing.
