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 therefore 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.
Use of Solvents
It has been found that some types of solvent used for cleaning circuitry will in fact melt the plastic-
covered components.
The life of the controls may be extended by periodic (every 100 hours of use) application of small
quantities of light lubricant to the spindles, threads and knob grub screw (’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 they may leak and corrode the surrounding
electronics.
Detector Not Operating
(A)
Check the condition of the batteries.
(B)
Change the batteries and ensure the connections are correct and secure.
Battery life can vary tremendously between makes, therefore your ’new’ batteries may already
be insufficiently powerful to run your detector.
(C) Check that the search head cable connector is properly attached to the control box.
Oscillating Signal Accompanied by Slight Meter Fluctuation
(A)
This is 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.
Intermittent Sound From Speaker
(A)
This could be due to poor battery connections. Ensure they are tight and the batteries are
securely clipped into place.
(B) Radio transmission from a passing taxi or vehicle using radio transmitter equipment.
