Enable Ground Balance

The Enable GB option toggles between on or off as indicated by the green tick
in the check box to the right of the option. By default, the Enable GB option is
selected when the menu opens, and the check box is empty indicating that Ground
Balance is off.
1. Press Select to confirm Enable GB selection.
A green tick will appear in the check box and Ground Balance is enabled.
2. Press Select again to remove the green tick and disable Ground Balance.

Perform Auto Ground Balance

Ground Balance must be enabled to perform Auto Ground Balance.
1. Find a metal free location near the area being detected. This may not be easy in a
cluttered environment.
2. With the Ground Balance Quick Menu displayed, use the down arrow button to
highlight the Start GB option and press Select.
A message will be displayed to confirm Ground Balance in progress.
3. Lift the coil to approximately 1 foot (30 cm) above the ground, then lower it again
until it almost touches the ground. Repeat this movement several times.
Audio will provide feedback during the GB process. The audio should quickly get
quieter and upon successful completion will be totally quiet.
A second message will advise you when the GB process is complete.
4. If a complete Ground Balance is not achieved, repeat steps 2 and 3.
