IMPORTANT SERVICE SAFETY INFORMATION
1. SAFETY PRECAUTIONS
Before returning a unit to the customer, always make a safety
check of the entire unit, 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 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 assemblies in
the cabinet, 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 isolating resistor/
capacitor networks. Do not operate this or permit it to be
operated Without all protective devices correctly
installed and functioning .
b. Be sure that there are no cabinet openings through which
an adult or child might be able to inser t 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.
c. Leakage current hot check - with the unit 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) 1410 (50.7). WITH THE
UNIT 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 Unit (antennas, handle bracket, metal cabinet, screw
heads , metallic overlays, control shaft, 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 unit power cord plug in
the outlet and repeat test .
ANY MEASUREMENTS NOT WITHIN THE LIMITS
SPECIFIED HERENING INDICATE A POTENTIAL SHOCK
HAZARD THAT MUST BE ELIMINATED

UNIT TO THE CUSTOMER.

d. Insulation resistance test cold check:
unplug the power supply cord and connect a jumper wire
between the two prongs of the plug .
Turn on the power switch of the unit.
Measure the resistance with an ohmmeter between
jumpered AC PLUG AND EACH Exposed metallic cabinet
part on the unit, such as screw heads, antenna, control
shafts, handle brackets, etc. When the exposed metallic
part has a return path to the chassis , the reading should
be between 1 and 5.2 megohms. When there is no return
path to the chassis, the reading must be infinite If it is
not within the limits specified, there is the possibility of a
shock hazard, and the unit must be repaired and
rechecked before it is returned to the customer.

2. PRODUCT SAFETY NOTICE
some electrical and mechanical par ts 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. Par ts
that have special safety characteristics are identified by
a on schematic and parts list. Use of a substitute
replacement that dose not have the same safety
characteristics as the recommended replacement par t
might create shock, fire, and/or other hazards. Product
safety is under review continuously and new instructions are
issued whenever Appropriate.
3. Servicing precautions
CAUTION: before servicing the unit covered by this service
by this service manual and its supplements. Read and follow
the SAFETY PRECAUTIONS on this page.
NOTE: if unforeseen circumstances create a conflict
between the following servicing precautions and any of the
Safety precautions, always follow the safety precautions.
Remember: safety first.
General servicing precautions.
a. Always unplug the unit s AC power cord from the AC
power source Before:
(1)removing or reinstalling any component, circuit board,
module or any other unit assembly.
(2)disconnecting or reconnecting any unit electrical plug or
other Electrical connection.
(3)connecting a test substitute in parallel with an electrical
capacitor caution: a wrong part substitution or incorrect
polarity installation Of electrolytic capacitors may result in
an explosion hazard
b. Do not defeat any plug/socket b+ voltage interlocks with
which the unit covered by this service manual might be
equipped.
c. Do not apply AC power to this unit and/or any its electrical
assemblies unless all solid-state device heat sinks are
correctly installed.
d. Always connect a test unit instrument s ground lead to
the unit s chassis ground before connecting the test
instrument s positive lead always remove the test
instrument s ground lead last.
4. Laser precautions
Warning!
(1)When servicing.(In case it isnecessary to confir m laser
Beam emission ) be sure not toplace your eyes any
closer than1or 30cm from the surface of the objective
lens on the optical pickup block.
HANDLING THE LASER PICKUP
( 2)Laser Diodesare Extremely Susceptibleto damage from
static electricity even if a static discharge dies not ruin
the diode, it can shorten its life or cause it to work
improperly.When replacing the pickup, usea conductive
maton the floorand desk and wear a wrist band
connected to groundthrough a 1Mohm resistor
to protect the laser diode from static damage. If thelens
should get dusty, blow off thedust carefully fromthe
object.
(3)There areno adjustable partsin the pickup assembly. If it
is defective, replace the wholepickup assembly.
CAUTION: USE OF CONTROLS, ADJUSTMENTS OR
PERFORMANCE OF PROCEDURES HEREIN MAY
DANGER: IF INTERLOCK FAILS OR IS DEFEATED, THE LASER
RESULT IN HAZARDOUS RADIATION
LIGHT IS ABLE TO FUNCTION. THE LASER IS
INVISIBLE, AVOID DIRECT EXPOSURE TO BEAM.
