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.

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:

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.
