1.8.2. LIVE ELECTRICAL SECTIONS

All the electrical sections of the unit supplied with AC power by the AC power cord are live.

Never disassemble the unit for service with the AC power supply plugged in.

CAUTION:

AC voltage is supplied to the primary side of the power supply unit. Therefore, always unplug the AC power cord before
disassembling for service.

1.9. SERVICE PRECAUTIONS

1.9.1. PRECAUTIONS TO PREVENT DAMAGE FROM STATIC ELECTRICITY

Electrical charges accumulate on a person. For instance, clothes rubbing together can damage electric elements or change
their electrical characteristics. In order to prevent static electricity, touch a metallic part that is grounded to release the static
electricity. Never touch the electrical sections such as the power supply unit, etc.
