1. SAFETY PRECAUTIONS
GENERALGUIDELINES
1. IMPORTANTSAFETY NOTICE
There are special components used inthisequipment which are
important for safety. These parts are marked by inthe Schematic
Diagrams, CircuitBoard Layout, Exploded Viewsand
2

Replacement Parts List. Itisessential that these criticalparts
shouldbe replaced with manufacturer’sspecified parts to prevent
X-RADIATION, shock, fire, or other hazards. Donot modifythe
original design without permission of manufacturer.
2. AnIsolation Transformer shouldalwaysbe used during the
servicing of AC Adaptor whose chassisisnot isolated from the
AC power line. Use atransformer of adequate power rating as this
protects the technician from accidents resulting inpersonalinjury
from electrical shocks. Itwill also protect AC Adaptor from being
damaged byaccidental shorting that mayoccur during servicing.
3. When servicing, observe the original lead dress. Ifashort circuit
isfound, replace all parts which have been overheated or
damaged bythe short circuit.
4. After servicing, see to itthat all the protective devices such as
insulation barriers, insulation papers shields are properly
installed.
5. After servicing, make the following leakage current checks to
prevent the customer from being exposed to shock hazards.
LEAKAGE CURRENTCOLD CHECK
1. Unplug the AC cord and connect ajumper between the two
prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the
jumpered AC plug and each exposed metalliccabinet part on the
equipment such as screwheads, connectors, control shafts, etc.
When the exposed metallicpart has areturn path to thechassis,
the reading shouldbe between 1M and 5.2M . When the
exposed metal does not have areturn path to the chassis, the
reading must be infinity.
LEAKAGE CURRENTHOTCHECK
(See Figure 1.)
1. Plug the AC cord directlyinto the AC outlet. Donot use an
isolation transformer for thischeck.
2. Connect a1.5k , 10 Wresistor, inparallel with a0.15 F
capacitor, between each exposed metallicpart on the set and a
good earth ground, as showninFigure 1.
3

3. Use an AC voltmeter, with 1k /Vor more sensitivity, to measure
the potential across the resistor.
4. Check each exposed metallicpart, and measure the voltage at
each point.
5. Reverse the AC plug inthe AC outlet and repeat each of the above
measurements.
6. The potential at anypoint shouldnot exceed 0.75 VRMS. A
leakage current tester (Simpson Model 229 or equivalent) maybe
used to make the hot checks, leakage current must not exceed 1/2
mA. Incase ameasurement isoutside of thelimits specified, there
isapossibilityof ashock hazard, and the equipment shouldbe
repaired and rechecked before itisreturned to the customer.

2. PREVENTION OF ELECTRO STATIC DISCHARGE
(ESD) TO ELECTROSTATICALLY SENSITIVE (ES)
DEVICES
Some semiconductor(solidstate) devices canbe damagedeasilybystatic electricity. Such
components commonlyare calledElectrostaticallySensitive (ES) Devices. Examples of typical
ES devices are integratedcircuits and some field-effect transistorsand semiconductor"chip"
components. The following techniques shouldbe usedtohelpreduce the incidence of
component damage causedbyelectrostatic discharge (ESD).
1. Immediatelybefore handling anysemiconductor component or
semiconductor-equipped assembly, drainoff anyESDon your
bodybytouching aknownearth ground. Alternatively, obtainand
wear acommerciallyavailabledischarging ESDwrist strap,which
shouldbe removed for potential shock reasons prior to applying
power to the unitunder test.
2. After removing an electrical assemblyequipped with ES devices,
place the assemblyon aconductive surface such as aluminum
4

foil, to prevent electrostaticcharge buildup or exposure of the
assembly.
3. Use onlyagrounded-tipsoldering iron to solder or unsolder ES
devices.
4. Use onlyan antistaticsolder removal device. Some solder
removal devices not classified as "antistatic(ESDprotected)" can
generate electrical charge sufficient to damage ES devices.
5. Donot use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Donot remove areplacement ES device from its protective
package until immediatelybefore you are readyto install it. (Most
replacement ES devices are packaged with leads electrically
shorted together byconductive foam, aluminum foil or
comparableconductive material).
7. Immediatelybefore removing the protective material from the
leads of areplacement ES device, touch the protective material to
the chassisor circuitassemblyinto which the device will be
installed.
CAUTION :
Besure no power isapplied to the chassisor circuit, and observe
all other safetyprecautions.
8. Minimize bodilymotions when handling unpackaged replacement
ES devices. (Otherwise harmless motion such as the brushing
together of your clothes fabricor the lifting of your foot from a
carpeted floor can generate staticelectricity(ESD)sufficient to
damage an ES device).
3. X-RADIATION
(Formodel withMonochrome EVF)
WARNING :
1. The potential source of X-Radiation inEVF sets isthe High
Voltage section and the picture tube.
2. When using apicture tube test jigfor service, ensure that jigis
capableof handling 10 kV without causing X-Radiation.
NOTE :
5

Itisimportant to use an accurate periodicallycalibrated high
voltage meter.
3. Measure the High Voltage. The meter (electrostatictype) reading
shouldindicate 2.2kV±0.1kV. Ifthe meter indication isout of
tolerance, immediate service and correction isrequired to prevent
the possibilityof premature componentfailure. To prevent an X-
Radiation possibility, itisessential to use the specified picture
tube.

5.1. SERVICENOTES
5.1.1. EXTENSION CABLES FOR SERVICE POSITION
Using the following Extension Cables, place the unit as shownforcheck and service.
Extension Cables (No.5 ~ No.8) are usedforimproving serviceability. (Theyare not necessarily
used.)
Note :
1. The LCD open/close SW. isfor changing between LCD Displayor
EVF Display. When turning on LCD Display, place some paper or
tape, etc. on LCD open/close SW. so that thisSW. staysON.
2. (For earlyproducts)
Besure to attach the Short JIG C.B.A. on Connector B3. Refer to "
SHORT JIG C.B.A."
