Troubleshooting - Radio Shack 63-3011 Owner's Manual

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
The detector displays or
sounds false signals.
The detector sounds only one
kind of tone, and discrimina-
tion does not work.
The detector sounds a con-
stant loud tone or constant
repeating tones.
The detector does not turn
on, has weak volume, will not
tune properly, operates errati-
cally, or drifts.

SUGGESTION
The sensitivity might be set too high. Adjust
counterclockwise.
SENSITIVITY
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.
