REPLACING THE COIL
Attention!
Before you replace the coil, find a clean section of ground, be-
cause after a coil replacement a ground balance is required.
Or, if a clean place cannot be found, have a piece of ferrite, or use a piece
of red brick. Secure the desired coil on the rod, wrap the wire around the
rod and plug the connector into the control box.
Hold the device at a distance of half a meter between the coil and the
ground and away from metal objects, turn on the unit while holding
down the button
on the instrument panel. Keep the button
pressed until
the detector stops playing the melody, and
the screen for a
short time will display the value of the work-
ing frequency of the coil.
Attention!
The exact frequency displayed can vary depending on the coil
and software and is automatically calculated by the device. For example a
Coil with a frequency 7.0 kHz, can vary ± 20 Hz.
After this, your device will automatically navigate into the ground bal-
ancing mode. (Fig. 15) Perform the auto ground balance on the clean
area of ground you located prior to changing the coil. Refer to
appropri-ate
paragraph
under section “Ground Balance”.
Alternatively if a section of clean ground cannot be located perform the
balance proce-dure using
piece of ferrite orred brick. Refer to the
instruction
pertaining to this under the section “Ground Balance”
Pressing
exits the balancing mode to work with the new coil.
