Controls - Fisher Labs F75 User Manual

ON-OFF & VOLUME Knob (Under the elbow)
This knob turns the machine on or off, and controls speaker volume and headphone
volume. Knob position has no effect on detector's sensitivity or susceptibility to noise
from electrical interference
The F75 has two controls on the front panel, MENU and SETTINGS.
MENU Pushbutton (Red button on right of the front panel)
Push the MENU button to:
1. Step through the menu selections on the display.
With each push of the button, the next menu selection will be highlighted.
The SETTINGS knob then allows you to change values for the highlighted
selection.
2. Recall the last setting which you adjusted.
After you have adjusted a setting, an indicator will remain highlighted next to this
menu selection. One push of the button will recall that selection and display the
stored value.
This recall function is useful for a value you want to adjust frequently, such as the
ground balance setting. In order to adjust a stored value with the SETTINGS
knob, you must first press the MENU button to reactive the user interface.
SETTINGS Knob (On the left of the front panel)
Rotate the SETTINGS knob to:
1. Change the setting (or value) of the highlighted menu selection you have chosen.
2. Select the operating MODE when the top line of the menu is highlighted.
When used to switch back and forth between the DISCRIMINATION mode and
ALL METAL modes, the detector changes modes as soon as the corresponding
selection is highlighted. The All Metal modes are used to detect all metal objects,
including small or deep objects. Use the Discrimination mode to ignore trash metal
such as nails, foil, or pull-tabs.
NOTE: When the menu selection highlight disappears , the SETTINGS knob is
deactivated. If settings values do not change when the SETTINGS knob is rotated, press
the MENU button to reactivate the user interface.
TRIGGER SWITCH (Under the display in front of your hand)
While the trigger is pulled back, metal objects are temporarily detected without the need
for searchcoil motion. This aids in pinpointing the exact location of objects which were
found while searching in the Discrimination or All Metal modes.
When the trigger is pushed forward, FASTGRAB automatic ground balancing is activated.
The internal computer measures the magnetic properties of the soil in order to cancel
interference from naturally-occurring minerals in the ground. After the detector measures
the soil in this manner, the detector then uses this information to control operation in both
the All Metal and Discrimination search modes.
