TROUBLESHOOTING GUIDE
Problem
Reason
Suggestion
The detector
sounds false
signals.
The detector may receive
interference and false signal
from broadcast antenna and
other electronic lines
- Change searching place
- Wait for some time to
check again
The humidity of environment
may be extremely high
The detector
sounds false
signals.
Sensitivity set too high/
environmental electromagnetic
interference
- Reduce SENSITIVITY
- Sweep the search coil
more slowly and hold the
detector correctly
- Keep two detectors at
least 6 meters(20’) apart
Sweeping the detector’s search
coil too fast or at wrong angle
Using 2 detectors in close
proximity
The detector
sounds false
signals.
There may be over one kind of
metal targets
- Reduce the sensitivity to
eliminate the detection of
the deeper target
- Sweep the search coil with
different angles
- Re-plug it properly
- Replace batteries
The detector can’t identify the
target. Sometimes, oxidized
metal also causes the excursion
of target arrow and tone.
Five-pin cable not connected
well
Dead battery
CARE AND MAINTENANCE
- Handle the detector gently and carefully. Dropping it can damage circuit boards and
can cause the detector to work improperly.
- Use the detector only in normal temperature environments. Temperature extremes
can shorten the life of electronic devices, causing internal damage to the detector.
- Keep the detector away from dust and dirt, which can cause premature wear and
tear of parts.
- Wipe the detector with a damp cloth occasionally to keep it looking new. Do not use
harsh chemicals, cleaning solvents, or strong detergents to clean the detector.
CAUTION
- The search coil is water proof, and it can be completely under the fresh water or
sea water. Please be careful to avoid the water enter into machine body. Sea water
may erode the search coil. Please always use fresh water to clean the search coil
after detection in sea water.
- Change or damage the inner components will cause the detector fault, and such
fault is not within our warranty.
