TROUBLESHOOTING
If you have problems, here are some suggestions that might help. If none of these
suggestions help, take your detector to your local RadioShack store for assis-
tance.
PROBLEM
SUGGESTION
The detector displays or
sounds false signals.
The sensitivity might be set too high. Adjust
SENSITIVITY
counterclockwise.
You might be sweeping the detector’s search-
coil too fast or at the wrong angle. Sweep the
searchcoil more slowly and hold the detector
correctly. See “Using the Detector” on
Page 10 and “Pinpointing a Target” on
Page 12.
The detector might sound a false signal if it
detects some types of heavily oxidized met-
als. Try pinpointing the target from several dif-
ferent angles (see “Pinpointing a Target” on
Page 12). If the detector does not display and
sound the same signal each time, the target is
probably heavily oxidized metal.
The detector sounds only one
kind of tone, and discrimina-
tion does not work.
DISC/ALL METAL/TONE
is set to
ALL METAL
or
DISC
. This is not a malfunction.
Set
DISC/ALL METAL/TONE
to
TONE
(see
“DISC/ALL METAL/TONE” on Page 8).
The detector sounds a con-
stant loud tone or constant
repeating tones.
The batteries might be weak. Replace the bat-
teries.
You are operating the detector near another
detector or near power lines. Power lines can
interfere with the frequency that the detector
operates on.
The detector does not turn
on, has weak volume, will not
tune properly, operates errati-
cally, or drifts.
The batteries might be weak. Replace the bat-
teries.
