on the label affixed to the back of the unit.
1.2. SAFETY PRECAUTIONS
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use only the manufacturer's recommended
components of safety.
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 hazard.
1.3. 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, such as
screwheads, antenna, control shafts, handle brackets, 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.
