1-1 Safety Precautions
1) Before returning an instrument to the customer,
always make a safety check of the entire instrument,
including, but not limited to, the following items:
(1) Be sure that no built-in protective devices are
defective or have been defeated during servicing.
(1)Protective shields are provided to protect both
the technician and the customer. Correctly replace
all missing protective shields, including any
removed for servicing convenience.
(2)When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in place
all protective devices, including, but not limited to,
nonmetallic control knobs, insulating fish papers,
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.
(2) Be sure that there are no cabinet openings through
which adults or children might be able to insert
their fingers and contact a hazardous voltage. Such
openings include, but are not limited to, excessively
wide cabinet ventilation slots, and an improperly
fitted and/or incorrectly secured cabinet back
cover.
(3) Leakage Current Hot Check-With the instrument
completely reassembled, plug the AC line cord
directly into a 230V(220V ~ 240V) 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 Standardsp
institute (ANSI) C101.1 Leakage Current for
Appliances and Underwriters Laboratories (UL)
1270 (40.7). With the instrument’s AC switch first in
the ON position and then in the OFF position,
measure from a known earth ground
(metal water pipe,
conduit, etc.) to all exposed metal parts of the
instrument (antennas, handle brackets, metal
cabinets,
screwheads, metallic overlays, control shafts,
etc.), especially any exposed metal parts that offer
an electrical return path to the chassis.
Any current measured must not exceed 0.5mA.
Reverse the instrument power cord plug in the outlet
and repeat the test. See Fig. 1-1.
Any measurements not within the limits specified
herein indicate a potential shock hazard that must
be eliminated before returning the instrument to
the customer.
Fig. 1-1 AC Leakage Test
(4) Insulation Resistance Test Cold Check-(1) Unplug
the power supply cord and connect a jumper wire
between the two prongs of the plug. (2) Turn on the
power switch of the instrument. (3) Measure the
resistance with an ohmmeter between the
jumpered AC plug and all exposed metallic cabinet
parts on the instrument, such as screwheads,
antenna, control shafts, handle brackets, etc. When
an exposed metallic part has a return path to the
chassis, the reading should be between 1 and 5.2
megohm. When there is no return path to the chassis,
the reading must be infinite. If the reading is
not within the limits specified, there is the possibility
of a shock hazard, and the instrument must be
repaired and rechecked before it is returned to the
customer. See Fig. 1-2.

notes on or inside the cabinet, or 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 modications and the
addition of items such as auxiliary audio output
connections, might alter the safety characteristics of
this instrument and create a hazard to the user. Any
design alterations or additions 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:
(1) near sharp edges, (2) near thermally hot parts (be
sure that leads and components do not touch
thermally
hot parts), (3) the AC supply, (4) high voltage,
and (5) antenna wiring. Always inspect in all areas
for pinched, out-of-place, or frayed wiring, Do not
change spacing between a component and the
printed-circuit board. Check the AC power cord for
damage.
5) Components, parts, and/or wiring that appear to
have overheated or that are otherwise damaged
should be replaced with components, parts and/ or
wiring that meet original specications.
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-Some electrical and mechanical
parts have special safety-related characteristics
which are oen not evident from visual inspection,
nor can the protection they give necessarily be
obtained by replacing them with components rated
for higher voltage, wattage, etc. Parts that have
special safety characteristics are identied by
shading,
an ( )or a ( )on schematics and parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacement part might create shock, re and/or
other hazards. Product safety is under review
continuously and new instructions are issued
whenever appropriate.

1-2 Servicing Precautions
CAUTION : Before servicing units covered by this
service manual and its supplements, read and follow
the Safety Precautions section of this manual.
Note : If unforeseen circumstances create conict
between the following servicing precautions and any
of the safety precautions, always follow the safety precautions.
Remember: Safety First.
1-2-1 General Servicing Precautions
(1) a. Always unplug the instrument’s AC powercord
from the AC power source before (1) removing
or reinstalling any component, circuit board,
module or any other instrument assembly, (2)
disconnecting any instrument electrical plug or
other electrical connection, (3) connecting a test
substitute in parallel with an electrolytic capacitor
in the instrument.
b. Do not damage any plug/socket B+ voltage
interlocks with which instruments covered by
this service manual might be equipped.
c. Do not apply AC power to this instrument and
or any of its electrical assemblies unless all
solid-state device heat sinks are correctly installed.
d. Always connect a test instrument’s ground lead
to the instrument chassis ground before connecting
the test instrument positive lead. Always
remove the test instrument ground lead last.
(4) An insulation tube or tape is sometimes used and
some components are raised above the printed
wiring board for safety. e internal wiring is
sometimes clamped to prevent contact with heating
components. Install such elements as they
were.
(5) Aer servicing, always check that the removed
screws, components, and wiring have been installed
correctly and that the portion around the
serviced part has not been damaged and so on.
Further, check the insulation between the blades of
the attachment plug and accessible conductive
parts.
1-2-2 Insulation Checking Procedure
Disconnect the attachment plug from the AC outlet
and turn the power ON. Connect the insulation resistance
meter (500V) to the blades of the attachment
plug. e insulation resistance between each blade of
the attachment plug and accessible conductive
parts(see note) should be more than 1 Megohm.
Note : Accessible conductive parts include metal panels,
input terminals, earphone jacks, etc.
Note : Refer to the Safety Precautions section ground
lead last.

Precautions
1-3 ESD Precautions
Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid state) devices can be
damaged easily by static electricity.
Such components commonly are called Electrostatically
Sensitive Devices(ESD). Examples of typical ESD
devices are integrated circuits and some eld-eect
transistors and semiconductor chip components. e
following techniques should be used to help reduce
the incidence of component damage caused by static
electricity:
(1) Immediately before handling any semiconductor
component or semiconductor-equipped assembly,
drain o any electrostatic charge on your body by
touching a known earth ground. Alternatively,
obtain and wear a commercially available
discharging wrist strap device, which should be
removed for potential shock reasons prior to
applying power to the unit under test.
CAUTION : Be sure no power is applied to the chassis
or circuit, and observe all other safety precautions.
(8) Minimize body motions when handling
unpackaged replacement ESD devices.
(Otherwise harmless
motions such as the brushing together of your
clothes fabric or the liing of your foot from a
carpeted oor can generate static electricity
sucient to damage an ESD device).
(2) Aer removing an electrical assembly equipped
with ESD devices, place the assembly on a
conductive surface such as aluminum foil, to
prevent electrostatic
charge buildup or exposure of the assembly.
(3) Use only a grounded-tip soldering iron to solder or
unsolder ESD devices.
(4) Use only an anti-static solder removal devices.
Some solder removal devices not classied as
“anti-static” can generate electrical charges su cient to damage ESD devices.
(5) Do not use freon-propelled chemicals. ese can
generate electrical charges sucient to damage
ESD devices.
(6) Do not remove a replacement ESD device from its
protective package until immediately before
installing it. (Most replacement ESD
devices are packaged with leads electrically shorted
together by conductive foam, aluminum foil or
comparable conductive materials).
(7) Immediately before removing the protective
materials from the leads of a replacement ESD
device, touch the protective material to the
chassis or circuit assembly into which the device
will be installed.
Precautions
