DETAILED OPERATING INSTRUCTIONS
M (Mono) changes the way the coil transmits and receives its signals.
Operating in Mono, the coil has some of the characteristics of a
Monoloop coil. Use of Mono will often increase the sensitivity of the
detector but may also be a little more unstable in heavily mineralised
ground. Pinpointing will be off to the left of centre.
Cancel changes the electromagnetic field of the coil so that it is
particularly stable in areas of electrical interference. This position is ideal
in areas where the operator wants to detect close to suburbia
or under power lines etc.

Figure 5.1
Tuning should be done initially with the Coil switch in Double D or in
M (Mono). If the interference is still severe after completing the tuning
operation, change the Coil switch to Cancel and then re-tune the
detector again.
• Hold the detector at waist height and the coil vertical.
• Keeping the coil vertical, slowly move it through a half-circle around
your body.
• Listen for an increase in interference as you move the coil.
• When the interference is loudest, stop moving the detector, hold it
motionless in that position and momentarily press the Tune switch.
The detector will then scan through the available range of
transmission frequencies and automatically select the frequency that
results in the greatest reduction of noise from electromagnetic
interference.
• The end of tuning process (which takes approx. 60 sec.) is
announced by three beeps.
NOTE While the detector is selecting the preferred
frequency, the coil must be kept motionless and clear of
metal objects.

IMPORTANT
When tuning detector in close
proximity to other detectors, each
operator needs to take turns
tuning. Do not try to tune two
detectors at one time.
