9. Troubleshooting
The detector is emitting false signals.
The detector's sensitivity may be set too high. Try cutting back the sensitivity slightly until the false signal
disappears. Remember to sweep the detector slowly. Some false signals will occur on highly rusted metals, but
if the signal does not appear over the same area while sweeping over it again, then the target is usually not
worth further hunting.
The LCD readout is not locking or ID'ing while sweeping over the target. There is more than one
tone being emitted over the same target.
This will usually occur with the presence of more than one object. Objects of a metal unknown to the detector
will not be signalled. Sometimes, oxidation can also make the ID arrows and tones jump around. Try cutting
back the sensitivity slightly if it is set at a high value.
Your detector is unstable and emits a pulsing, distorted tone instead of a clear tone.
The presence of interfering signals, such as power lines or another detector nearby, may disturb the
frequencies of your metal detector.

Cleaning and Maintenance

Your CS300 metal detector is an example of superior design and craftsmanship. The following suggestions will
help you take care of your metal detector so you can enjoy it for years.
Handle the detector gently and carefully. Dropping it can damage circuit boards and cases 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, or damage the detector's exterior.
Keep the detector away from dust and dirt, which can cause premature wear 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.
Modifying or tampering with the detector's internal parts may cause malfunctions. The search coil is waterproof
and can be submerged in either fresh or salt water. However, do not let water enter the detector's control
housing. Rinse with fresh water after using the search coil in salt water to prevent corrosion of metal parts.
