the earth ground and exposed metal parts of the appliance
(input/output terminals, screwheads,metal overlays, etc.).
Plug the power supply cord directly into a 120V AC 60 Hz outlet
and turn Standby switch on. Any current meausred must not
exceed 0.5mA.
1. Replacing the fuses
This symbol located near the fuses indicates that the
fuse used is fast operating type. For continued protection against
