NOTdefeat
the earth grounding protection by using an extension cable,
power cable, or autotransformer without a protective ground conductor.

Caution
Before connecting the spectrum analyzer to the power source, you must set the
rear-panel voltage selector switch correctly to adapt the spectrum analyzer
to the power source. An improper selector switch setting can damage the
spectrum analyzer when it is turned on.
Set the instrument’s rear-panel voltage selector switch to the line voltage range
(115 V or 230 V) corresponding to the available ac voltage. See Figure l-2. Insert a small
screwdriver or similar tool in the slot and slide the switch so that the proper voltage label is
visible.
