prevent the customer from being exposed to a shock hazard.

e 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 Jumpered AC plug and each exposed metal cabinet part, such as

screwheads, antenna, control shafts, handle brackets, etc Eqmpment with antenna terminals should read between 3M9
and 5.2MSI to all exposed parts. (Fig. A) Equipment without antenna terminals should read approximately infinity to

all exposed parts. (Fig. 8)
Note: Some exposed parts may be isolated from the chassm by design. These will read infinity.

Ohmmeter

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 remstance test to

Ohmmeter

(Fig. B)

ReSistance = Approx 00

4. If the measurement is outside the speCIfied limits, there is a DOSSIbllltY of a shock hazard. The eqmpment should be
repaired and rechecked before it is returned to the customer
