Radio Shack 63-3011 - TESTING THE DETECTOR

TESTING THE
DETECTOR
To learn how the detector reacts to dif-
ferent metals, you should test it before
you use it the first time.
1. Turn on the detector by turning
SENSITIVITY
clockwise until it
clicks. The detector beeps and the
viewmeter’s needle swings to the
right, then returns to the left.
2. Adjust
SENSITIVITY
until it is about
halfway between
OFF
and
HIGH
.
3. Set
DISC/ALL METAL/TONE
to the
desired setting (see “DISC/ALL
METAL/TONE” on Page 8).
4. Lay the detector on a wooden or
plastic table, then remove any
watches, rings, or metal jewelry
you are wearing.
Note:
Never test the detector on a
floor inside a building. Most build-
ings have metal of some kind in
the floor, which will interfere with
the objects you are testing or
mask the signal completely.
5. Adjust the searchcoil so the flat
part points toward the ceiling.
6. Make sure the detector is set to
detect the type of metal you are
using to test it (see “Adjusting
DISC/TONE” on Page 12).
7. Slowly move a sample of the
material you want the detector to
find (such as a gold ring or a coin)
side-to-side 1–2 inches above the
face of the searchcoil.
Note:
If you are using a coin, the
detector will detect it more easily if
you hold it so a flat side (not the
edge) is parallel with the flat side
of the searchcoil.
If the detector detects the material,
it sounds a tone and the viewme-
ter’s needle swings to the right.
If the detector does not detect the
material, make sure
DISC/ALL
METAL/TONE
is correctly set for
the type of metal you are search-
ing for, then repeat this step.
