Troubleshooting; Care & Maintenance - Velleman CS150 Bedienungsanleitung

Because of the metal mixtures, target signals might not be in a "fixed" position. This effect makes these objects
very hard to detect accurately. (See "Fine-Tuning the Detector").

5. Troubleshooting

If your detector is not working as it should, follow these suggestions to see if you can eliminate the problem.
PROBLEM
The detector displays 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.
6. Care & Maintenance
Keep the metal detector dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that
corrode the electronic circuits.
Handle the detector gently and carefully. Dropping it can damage circuit boards and cases and can
cause the detector to not work properly.
Use and store the detector only in normal temperature environments. Temperature extremes can
shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.
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 can cause a malfunction and might invalidate its warranty.
The search coil supplied with the detector is waterproof and can be submerged in either fresh or salt water.
However, do not let water enter the detector's control housing. After using the search coil in salt water, rinse it with
fresh water to prevent corrosion of the metal parts.
The information in this manual is subject to change without prior notice.

You might be sweeping the detector's search coil too fast or at the
wrong angle. Sweep the search coil more slowly and hold the
detector correctly. See "Testing and Using the Detector" and
"Pinpointing a Target".
The detector might sound a false signal if it detects heavily oxidised
metals. Try pinpointing the target from several different angles (see
"Pinpointing a Target"). If the detector does not display and sound
the same signal each time, the target is probably heavily oxidised
metal.
There might be more than one target in the area you are searching.
The target might be a type of metal that the detector does not
recognise.
If the target is heavily oxidised, the detector might not display the
correct metal type. This is not a malfunction.
