Salt Damage
If you use your detector continually in a salty environment, particularly when the wind is blowing
off the sea, salty air can penetrate the control box.
Corrosion can occur in vital parts of the delicate electronic circuitry.
It is, therefor, recommended that precautions such as covering the control box with polythene be
taken to avoid damage.
The guarantee cannot cover such occurrences and any repairs needed because of salt water or spray
will be charged.
The Use of Solvents
It has been found that some types of solvent used for cleaning circuitry will in fact melt the plastic
covered components.
Clean the circuit board only with recognised circuit board cleaning agents.
The life of the controls may be extended by periodic (100 hours of use) application of small
quantities of light lubricant to the spindles, threads and knob grub screws (’3 in 1’ or similar
household oil is suitable).
This operation requires the knobs to be removed.
Light packing grease should be smeared on the threads of the locking collar, and at the same time,
the head fixing bolt. Do not store the detector in a damp place.
If the detector is to be stored, remove the batteries as the may leak and corrode the surrounding
electronics.
Detector Not Operating
(a)
Check the conditions of batteries.
(b)
Interchange batteries and ensure connections are correct and secure.
Battery life can vary tremendously between markers, therefore your ’new’ batteries may
already be insufficiently powerful to run your detector.
Oscillating Signal Accompanied by Slight Meter Fluctuation
(a)
Caused most often by outside equipment such as fluorescent lights, taxis, radios, power lines,
and other metal detectors working nearby. Little can be done to alleviate the problem except
to find a new site.
