1.4 SAFETY PRECAUTIONS
1.When servicing, set the ROTARY SWITCH to Off 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 cir- cuit.
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) is to 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] of the ROTARY SWITCH.
4.The value should be over 1 MΩ.
