1 INTRODUCTION
1.1. SAFETY PRECAUTIONS
1. Before servicing, unplug the AC power cord to prevent an electric shock.
2. When replacing parts, use only the manufacturer´s recommended components.
3. Check the condition of the power cord. Replace if wear or damage is evident.
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 perform the following insulation resistance test to prevent
the customer from being exposed to shock hazards.
1.2. INSULATION RESISTANCE TEST
1. Unplug the power cord and short the two prongs of the plug with a jumper 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, bottom frame, etc.).
Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.
4. If the measurement is outside the specified limits, there is a possibility of a shock hazard.
The equipment should be repaired and rechecked before it is returned to the customer.
1.3. FOR SERVICE TECHNICIANS
ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help prevent recurring malfunctions.
1. Cover the plastic part´s boxes with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on the worktable.
4. Do not touch the IC or LSI pins with bare fingers.

BATTERY CAUTION
CAUTION
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to manufacturer’s instruction.
manufacturer. Discard used batteries according to manufacturer’s instruction.
Disposal of lithium batteries should be perfomed by permitted, professional disposal firms knowledgeable in state govem-ment
federal and local hazardous materials and hazardous waste transportation and disposal requirements.
Battery continues to have no transportation limitations as long as they are separated to prevent short circuts and packed in
strong packaging.
Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their ulti-mate
disposition. This is a good practice for all types of commercial or industrial waste.
