SAFETY PRECAUTION (This safety precaution" is applied only in U S. A.)

Before servicing, unplug the power cord to prevent an electric shock.

. When replacing parts, use only manufacturer' 5 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.

prevent the customer from being exposed to a shock hazard.

o INSULATION RESISTANCE TEST

1. Unplug the power cord and short the two prongs of the plug with a jumper wire.

. Turn on the power switch.
. Measure the resistance value With ohmmeter between the jumpered AC plug and each exposed metal cabinet part, such as
Equipment with antenna terminals should read between 3M9

screwheads antenna, control shafts, handle brackets, etc.

. Before returning the serviced equipment to the customer, be sure to make the following insulation resistance test to

and 5.2MS2 to all exposed parts. (Fig. A) Equipment without antenna terminals should read approximately infinity to

all exposed parts. (Fig. Bl

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 equipmem should be

repaired and rechecked before it is returned to the customer.
