optimum performance on a particular site. The level is adjusted by rotating the
MENU/SCROLL control. An incorrect setting will result in a fluctuating signal on the RADAR
display and frequent ‘0’ targets on the ID display. To find the optimum ground setting, raise
and lower the head above an area of ground free from any targets then adjust the ground
setting for minimum audio fluctuation and ID indications. An alternative method is to set the
Pin Point gain to 8 and then lower the head to an area of ground free from any targets. If the
audio level increases then decrease the ground setting, if it decreases, (goes quiet), then
increase the ground setting.
NOTE: If BEACH is selected then an incorrect ground setting will result in frequent ID targets
in the range 3 to 6 depending on beach conditions. Adjust the ground setting as described
above.
