condition of batteries, with one LED indicating very low charge and full scale
indicating a fully charged battery.
These LEDs stay lit from 10 to 20 seconds depending on the version of the
detector.
If powering through the Power Connector using the NMT Power Supply, all of
the LEDs to the right of “Tag Threshold” will be on for 20 seconds.
After the initial battery condition display, the LEDs to the right of “Tag threshold”
go out and the microprocessor initializes itself. The detector is now ready to
detect noise or a CWT. If the Detector Sensitivity knob is set at the lowest
setting (completely counter clockwise) the two most left LEDs will be on. If the
sensitivity is adjusted clockwise then the second LED will go off and the third or
fourth LED will light. The LED bar graph shows the strength of the detected
signal plus noise. A lit LED confined to the left side of “Tag Threshold” indicates
a signal smaller than normally produced by a tag. When “Tag Threshold” is
reached, the bar of lit LEDs extends beyond the light labeled "Tag Threshold".
The detector signals the presence of a tag with both an audible beep and by
turning on the large round bright red LEDs near the center of the front and rear
panels.
There are three adjustments knobs: Detector Sensitivity, Gate Signal Delay, and
Gate Signal Duration. The recommended starting positions of these are:
1)
Detector Sensitivity turned to approximately 11:00 o'clock,
2)
Gate Signal Delay turned all the way down (full counter-clockwise), and
3)
Gate Signal Duration turned all the way up (full clockwise).
These controls should be further adjusted as described in Part 4.
