DETECTOR NOT OPERATING?
(a) Check the condition of batteries under load using the meter. (See Battery Check Procedure).
(b) Check that the search head is properly attached to the control box via the search head cable
connector.
(c) Interchange batteries and ensure connections are correct and secure. Battery life can vary
tremendously between makes, therefore your 'new' batteries may already be insufficiently
powerful to run the detector.
Oscillating Signal Accompanied By Slight Meter Fluctuation
(a) This could be due to poor battery connections. Ensure that they are tight and the batteries
are securely clipped into place.
(b) Loose search head cable connection - tighten.
(c) Interference from a vehicle using a radio transmitter or possibly a stationary source of
electromagnetic radiation - if this occurs then reduce the sensitivity. If the problem persists
then the best remedy is to wait until the transmission stops.
Intermittent Sound From Speaker
(a) This could be due to poor battery connections. Ensure that they are tight and the batteries
are securely clipped into place.
(b) Loose search head cable connection - tighten.
(c) Radio interference (see above).
The Detector Drifts Out Of Tune
(a) Temperature drift caused by change in air temperature when a machine is moved from a
house or car into the open. The greater the change in temperature the more the drift, and in
severe conditions 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.
