1. PRECAUTIONS
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 remove 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 opening 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 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) 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 and 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.
AC Leakage 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.
(4) Insulation Resistance Test Cold Check-(1) Unplug the
power supply cord and connect a jumper wore
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 re-pared and rechecked
before it is returned to the customer.

2) Read and comply with all caution and safety related
notes non or inside the cabinet, or on the chassis.
3) Design Alteration Warning-Do not alter of 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,
might alter the safety characteristics of this instrument
and create a hazard to the user. Any design alterations
or additions will make you, the service, responsible
for personal injury or property damage resulting there
from.
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 specifications. Additionally determine
the cause of overheating and/or damage and, if
necessary, take corrective action to remove and
potential safety hazard.
6) Product Safety Notice-Some electrical and mechanical
parts have special safety-related characteristics which
are often 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 identified 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 created shock, fire and/or other hazards.
Product safety is under review continuously and new
instructions are issued whenever appropriate.
1-2 Servicing Precautions
CAUTION: Before servicing Instruments covered by this
service manual and its supplements, read and follow the
Safety Precautions section of this manual.
Note: If unforeseen circument create conflict between the
following servicing precautions and any of the safety
precautions, always follow the safety precautions.
Remember; Safety First
1-2-1 General Serving Precautions
(1) a. Always unplug the instrument’s AC power cord 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 defeat 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.
Note: Refer to the Safety Precautions section ground
lead last.
(2) The service precautions are indicated or printed on the
cabinet, chassis or components. When servicing,
follow the printed or indicated service precautions
and service materials.
(3) The components used in the unit have a specified flame
resistance and dielectric strength.
When replacing components, use components which
have the same ratings, by ( ) or by ( ) in the
circuit diagram are important for safety or for the
characteristics of the unit. Always replace them with
the exact replacement components.
(4) An insulation tube or tape is sometimes used and some
components are raised above the printed wiring board
for safety. The internal wiring is sometimes clamped
2 - Cosmic Digital Technology Limited -

to prevent contact with heating components. Install
such elements as they were.
(5) After 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 plus 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. The 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.
1-3 ESD Precautions
Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid static electricity) devices can
be damaged easily by static electricity.
Such compo9nents commonly are called Electrostatically
Sensitive Devices (ESD). Examples of typical ESD devices
are integrated circuits and some field-effect transistors and
semiconductor chip components. The following techniques
of component damage caused by static electricity.
(1) immediately before handling any semiconductor
components or semiconductor-equipped assembly,
drain off 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.
(2) after 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 device.
(4) Use only an anti-static solder removal devices. Some
solder removal devices not classified as “anti-static”
can generate electrical charges sufficient to damage
ESD devices.
(5) Do not use freon-propelled chemicals. These can
generate electrical charges sufficient to damage ESD
devices.
(6) Do not remove a replacement ESD device from its
protective package until immediately before you are
ready to install it. (Most replacement ES 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 ES device touch the
protective material to the chassis or circuit assembly
into which the device will be installed.
CAUTION: Be sure no power is applied to the chassis or
circuit, and observe all other safety precautions.
(8) Minimize bodily motions when handling unpackaged
replacement ESD devices. (Otherwise harmless
motion such as the brushing together of your clothes
fabric or the lifting of your foot from a carpeted floor
can generate static electricity sufficient to damage an
ESD device).
