1. Safety Precaution
(This “Safety Precaution” is applied only in U.S.A.)
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use only manufacturer’s recommended
components for 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 make the following insulation resistance test to prevent the
customer from being exposed to a shock hazard.
- 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 ohmmeter between the jumper
AC plug and each exposed metal cabinet part, such as screw
heads, antenna, control shafts, handle brackets, etc. Equipment
with antenna terminals should read between 3M and 5.2M to
all exposed parts*. (Fig 1) Equipment without antenna terminals
should read approximately infinity to all exposed parts. (Fig 2)
*Note: Some exposed parts may be isolated from the chassis by
design. These will read infinity.
