TROUBLESHOOTING
If your detector is not working as it should, follow the suggestions below to see if
you can eliminate the problem. If you cannot, take the detector to your local Ra-
dioShack store for assistance.
PROBLEM
The detector dis;:ilays or sounds false
signals.
The display does not show the correct
metal type when the detector finds a
target. Or, the detector sounds more
than one type of tone when it finds a
target.
SUGGESTION
• The sensitivity might be set too
high. Adjust
SENSITIVITY.
• You might be sweeping the detec-
tor's searchcoil too fast or at the
wrong angle. Sweep the search-
coil more slowly and hold the
detector correctly. See "Outdoor
Testing and Use" on Page 12 and
"Pinpointing
a
Target"
on
Page 14.
• The detector might sound a false
signal if it detects some types of
heavily oxidized metals. Try pin-
pointing the target from several
different angles (see "Pinpointing
a Target" on Page 14). If the
detector does not display and
sound the same signal each time,
the target is probably heavily oxi-
dized metal.
• There might be more than one
target in the area you are search-
ing.
• The target might be a type of
metal that the detector does not
recognize.
• If the target is heavily oxidized,
the detector might not display the
correct metal type. This is not a
malfunction.
• The sensitivity might be set too
high. Adjust
SENSITIVITY.
