power from most of the instrument when you press the On/Standby switch.

cord.
4. Orient the instrument: Set the instrument so its bottom is down on the work
surface and its rear is facing you.
5. Remove line cord: Find the line cord on the rear cover. Pull the line cord
away to remove from the AC power connector. Reverse procedure to
reinstall.

fuse cap by turning it counterclockwise using a flat-bladed screwdriver, and
remove the line fuse. Reverse procedure to reinstall.
