DEFAULT OPERATION
The detector defaults to
ALL METAL
mode after powering on. In this
mode, all types of metals will be detected. An object’s probable
identification is indicated by the arrows at the top of the display. In
addition, the probable depth of coin-sized objects is indicated by the
large numeric indicator in the center of the display. All detected
objects will cause the depth indicator to illuminate. The depth
indication is not accurate for
larger objects; however, it will
provide accurate relative
depth indications. The
greater the distance an object
is from the searchcoil, the
greater its depth value.
DISC/ A-M Touch Pad
Pressing this touch pad will
cause the detector to toggle
between two operating
modes, DISCRIMINATION
and ALL-METAL. If the
detector is in the ALL-METAL mode (the default mode), pressing the
touch pad will change the detector into DISCRIMINATION mode. If
the detector is in the DISCRIMINATION mode, pressing the touch pad
will change the detector into ALL-METAL mode.
DISCRIMINATION MODE
Discrimination is used to eliminate unwanted objects from detection.
To enter this mode, from ALL-METAL mode, press the DISC/A-M touch pad.
After pressing DISC/A-M, the detector will:
• Beep twice
• Display an "R" under the left-most segment, Iron
Ferrous objects will not be detected in DISCRIMINATION mode.
Heavily oxidized ferrous objects will sometimes, however, be
detected, usually with a high tone and an indication to the right of
the target identification scale.
To increase the level of discrimination, press the DISCRIMINATION
▲
Basic Operation (continued)
11
touch pad. Each time the
▲
pad is depressed, an additional "R" will
appear, thus eliminating from detection the objects which fall into the
corresponding categories.
To decrease the level of discrimination, press the DISCRIMINATION
▼
touch pad. Each time the
▼
pad is depressed, an illuminated "R" will
disappear, thus returning to detection the objects which fall into the
corresponding categories.
Discrimination Mode is a fixed-start-point elimination system. Objects
are cumulatively eliminated as the level of discrimination increases.
NOTCH MODE
To selectively eliminate a category from detection within the metallic
spectrum, use the NOTCH Mode.
Technical Note:
The NOTCH touch pad causes the status of an "R" segment to
toggle between ON and OFF.
To use the NOTCH Mode:
The NOTCH touch pad can be depressed at any time. But for
first-time use, place the detector in ALL-METAL mode.
A first demonstration is best accomplished as follows:
1) Turn the power OFF.
2) Turn the power ON.
3) Press NOTCH.
A flashing "R" will appear under the IRON segment.
4) Press the DISCRIMINATION
▲
touch pad several times
Notice that the "R" moves upon each press of the
DISCRIMINATION
▲
touch pad.
5) Press NOTCH again.
The flashing "R" will become permanently illuminated.
If an object has been “notched-out”, you can return it to detection
status. To “un-notch” a category:
1) Press NOTCH.
2) Move the flashing “R” over the permanently illuminated “R”.
3) Press NOTCH again.
