If you would like to set the internal controls, please continue with this section of the Quickstart. If you
would prefer not to set the internal controls, please switch the TUNE SPEED to MOTION DISC and skip
down to the section marked
"Perform Air Test in MOTION DISC Mode."
Setting the Volume control: The Volume control is the only potentiometer that is located on the printed
circuit board. To adjust your Volume control, open the case and put a slight pressure on the battery pack.
After you hear the battery test you will be able to adjust the volume that you hear in the headphones to a
comfortable level. Use your screwdriver and turn the potentiometer clockwise for more volume and
counterclockwise for less volume. Take some time and find the most comfortable level for you.
Setting the Threshold control: The Threshold control is located on the back of the faceplate/switch set
and is the potentiometer closest to the edge of the faceplate. As explained in the
"Perform Audio
Battery Test"
section, the threshold is a slight steady tone that is used as a reference point to judge
targets by. Some targets may be small enough or deep enough that they will not be able to generate an
audio signal by themselves. By monitoring a threshold, you already have a signal so changes in that
signal will be easier to hear. However, if the threshold is set too loud or too soft, small changes in the
signal will be hard to hear. To adjust your Threshold level, open the case and put a slight pressure on the
battery pack. After the battery test, use your screwdriver to turn the potentiometer clockwise to increase
the threshold tone and counterclockwise to decrease the threshold tone. Take some time to find the best
threshold tone for you.
Setting the Sensitivity control: The Sensitivity control is on the back of the faceplate/switch set and is the
closest to the center of the faceplate. To set the Sensitivity control, you must first switch to MOTION
DISC. The Discriminate circuit uses a silent search mode meaning that no sound will be heard until the
coil goes over a target. The most common use of the detector will be to hunt in the MOTION DISC
Mode and then switch to an ALL MET Mode to pinpoint a target. This will give you the advantage of
ignoring unwanted targets and not having to listen to the threshold hum until you are ready to recover a
target.
The ALL MET circuit uses a single channel to detect various metals. The MOTION DISC circuit uses
two different channels, then amplifies and filters the signals, and then compares the two to determine
whether or not to beep at a target. While this is a great advantage for ignoring unwanted targets, it can
