Controls
The control knob has three positions: OFF, VOLTAGE SET, and
ON.
In the OFF position all power is off, including the high voltage
output. Turning the knob clockwise 30 degrees to the VOLTAGE
SET position turns on the high voltage output, blinks the red LED,
pulses the run tone, and turns on the display. The voltage displayed
is in kilovolts (thousands of volts.) A screwdriver can be placed
through the hole in the rear of the knob nearest the operator to
change the voltage setting. Turning the screwdriver clockwise will
increase the voltage. In the ON position the voltage adjustment is
not accessible. In this position the unit is in the normal running
mode with the red LED on steady, the run tone steady, and the
display off.
CAUTION!
DO NOT TOUCH bare ground wire when the detector is on.
DO NOT CUT the ground cable to a shorter length.
