8.1 Electrical System

In the advent of a base malfunction, the first item to investigate is the input power. Be
certain that the power cord is plugged into a live electrical outlet and the power switch is
switched on. A green "Power On" light illuminates indicates this.
Before removing any sheet metal covers the base must be turned off and
unplugged. Dangerous high voltage may be present in the circuitry under the
covers. Only trained technicians should perform this task.
