1.4 SAFETY PRECAUTIONS
1. When servicing, set the ROTARY SWITCH to
Off ( O ) and unplug the power cord.
2. Observe the original lead dress.
If a short circuit is found, replace all parts which
have been overheated or damaged by the short
circuit.
3. After servicing, make an insulation resistance test
to prevent the customer from being exposed to
shock hazards.
1.5 INSULATION RESISTANCE TEST
1. Unplug the power cord and connect a jumper
between 2 pins (black and white).
2. The grounding conductor (green or green and yel-
low) isto be open.
3. Measure the resistance value with an ohm meter
between the jumpered lead and each exposed
metallic part on the equipment at all position
[except Off ( 0 )] of the ROTARY SWITCH.
4. The value should be over 1 M_.
