CS150

• Some nails, nuts, bolts, and other iron objects (such as old bottle caps) oxidise and create a

"halo" effect. A halo effect is caused by a mixture of natural elements in the ground and the

oxidation created by different metals. 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").

7. Care and maintenance

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.

8. Troubleshooting

If your detector is not working as it should, follow these suggestions to see if you can eliminate the

problem.

PROBLEM SUGGESTION

The detector displays or

sounds false signals

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.

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.

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.
