1. INTRODUCTION
1.1. SAFETY PRECAUTIONS
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use onlythe manufacturer’srecommended
components.
3. Check the condition of the power cord. Replace ifwear or damage
isevident.
1

4. After servicing, be sure to restore the lead dress, insulation
barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure
to make the following insulation resistance test to prevent the
customer from being exposed to shock hazards.
1.2. INSULATIONRESISTANCETEST
1. Unplug the power cord and short the twoprongs of the plug with
ajumper wire.
2. Turn on the power switch.
3. Measure the resistance value with an ohmmeter between the
jumpered AC plug and each exposed metal cabinet part
(screwheads, control shafts, handlebrackets, etc.). / "Note: Some
exposed parts maybe isolated from the chassisbydesign. These
will read infinity.
4. Ifthe measurement isoutside the specified limits, there isa
possibilityof ashock hazard. / The equipment shouldbe repaired
and rechecked before itisreturned to the customer.
Resistance=more than5 M ohm/ (at DC 500V)
1.3. BATTERYCAUTION
CAUTION:
2

Danger of explosion ifbatteryisincorrectlyreplaced. Replace only
with the same or equivalent type recommended bythe
manufacture. Discard used batteries according to following caution:
/
Disposal of lithium batteries shouldbe performed bypermitted,
professional disposal firms knowledgeableinstate government
federal and local hazardous materialsand hazardous waste
transportation and disposal requirements. / Batterycontinues to
have no transportation limitations as long as theyare separated to
prevent short circuits and packed instrong packaging. /
Commercial firms that dispose of anyquantityof lithium cells
shouldhave amechanism inplace to account for theirultimate
disposition. Thisisagood practice for all types of commercial or
industrial waste. /

1.4. FORSERVICETECHNICIANS
ICs and LSIs are vulnerable tostatic electricity. / Whenrepairing, the following precautions will
helpprevent recurring malfunctions.
1. Cover the plasticparts boxes with aluminum foil.
2. Ground the soldering irons.
3. Use aconductive on the worktable.
4. Donot touch ICor LSI pins with bare fingers.
