Front Controls

Reset This toggle switch when pushed momentarily down will reset the detector

Frequency Counter This toggle switch when pushed momentarily up will count the frequency on

the loop. This count is displayed by the Red Led blinks, each blink

represents frequency of 10K Hz. Count between 3 to 13 blinks confirms

that the loop detector is tuned to the loop.

Frequency This toggle switch controls the loop frequency. Set different frequencies

on adjacent loops. Verify frequencies with the frequency counter by

counting the Red LED blinks.

Back Controls

Sensitivity This rotary switch controls the detector sensitivity. During normal operation

the sensitivity level is set to 3 or 4.
