Setting the line Voltage Selector Switch
CAUTION
Before connecting the cable TV analyzer to the power source, you must set
the rear-panel voltage selector switch correctly to adapt the cable TV analyzer
to the power source. An improper selector switch setting can damage the
cable TV 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 up or down so that the proper voltage label is visible.
