Warning messages are shown at the bottom of the display. Messages that may appear are
as follows:
Overload
It appears on the display simultaneously with the overload alarm. This happens when the
search coil encounters a near surface or a very large object. The device reverts back to
normal operation if you lift the coil up. If the alarm and the message continue along a long
line, you may be over a long metal such as a pipe.
In case of high mineralization, the device may overload. If the cause of overloading is not
a large metal, it may be the ground itself and this situation may be overcome by lowering
the gain.
NOTE:
You can increase or decrease the overload volume with the on/off button. When the
volume of the device is at maximum, the overload volume will be low. As the volume of the
device is lowered, the overload volume wil increase.
Pump the Coil
This message appears when the trigger is pushed forward for ground balancing. It does not
indicate any error or problem. It only indicates what should be done.
Check Coil
It indicates an interruption in the search coil transmitter signal. The search coil connector
may be unattached, loose or disconnected. If you own another detector with the same coil
connector, please be sure that you have not attached the wrong coil by mistake. If none of
the above exists, the search coil or its cable may have a defect. If the issue continues when
you change the search coil, there may be an issue in the coil control circuit.
