m SAFETY PRECAUTION
Before servicing, unplug the power cord to prevent an electric shock.
When replacing parts, use only manufacturer’s recommended components for safety.
Check the condition of the power cord. Replace if wear or damage is evident.
After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.
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.
OV GN >
e INSULATION RESISTANCE TEST
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turnon the power switch.
3.
Measure
the
resistance
value
with
ohmmeter
between
the
jumpered
AC
plug
and
each
exposed
metal
cabinet
part,
such
as
screwheads
antenna,
control
shafts,
handle
brackets,
etc.
Equipment
with
antenna
terminals
should
read
between
3MQ2
and
5.2MQ
to
all
exposed parts.
(Fig.
A)
Equipment
without
antenna
terminals
should read
approximately
infinity
to
all
exposed
parts.
(Fig.
B)
Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.
