When servicing, set the POWER of CONTROL BOARD 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 circuit. 3. After servicing, make an insulation resistance test to prevent the customer's exposure to shock hazards. 1. Unplug the power cord and connect a jumper between 2 pins (black and white). 2. The grounding conductor (green or green and yellow) 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 Mode [except POWER OFF]. 4. The value should be over 1 MΩ. -3-
