Oscillating Signal
(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.
Intermittent Sound From Speaker
(a) This could be due to poor battery connections. Ensure they are tight and the batteries are
securely clipped in place.
(b) Radio transmission from passing taxi or vehicle using radio transmitter equipment (see above).
(c) Loose speaker, in which case the speaker needs fastening back into place. Refer to
dealer/service agent.
The Detector Drift Out of Tune
(a) Temperature drift caused by the change in air temperature when a machine is moved from a
house or a car into the open. Allow the detector temperature to stabilise.
The greater the change in temperature the more drift, and up to 30 minutes may be needed for
the electronic circuitry to acclimatise itself.
(b) Sometimes battery drain can cause drift of signal. Replace batteries and this should help to
maintain a stable signal.
Before returning a detector for repair to the retailer ensure you have done the
following :
(a) Read instructions thoroughly.
(b) Tried new batteries and checked procedure outlined above.
(c) Spoken to the local dealer about performance of the detector, especially if you are still
unfamiliar with metal detectors in general.
This equipment conforms to the EMC Directive 89/336/EEC.
However, system performance may be impaired by unusually strong electromagnetic fields.
