lar area around the position of the locator in which the erase
button was pressed. This circular area, referred to as the erase
zone, may be affected by the magnitude of the magnetic field
of the fence and the distance from the fence when the button
was pressed. In extreme cases, there may be a point where
you may have to press the Erase button again as you ap-
proach the fence.
If you inadvertently erase the object you are directly over,
simply move the locator to one side and activate the Erase
button and return to a normal search procedure.
Battery Replacement: Turn the power off. Unscrew the
thumb screw on the battery cover between 2-5 turns. Lift the
cover off until the tab at the rear of cover clears the slot it is
located in. Remove the batteries by raising the batteries at
the junction or contact point of each set of two batteries. This
is the point where the two batteries contact each other. You
may prefer other methods of your choosing. Dispose of the
weak batteries properly. Insert the new batteries observing
the polarity markings located inside the battery wells. Install
the cover in the reverse manner. Do not over tighten the thumb
screw. Do not replace the batteries under raining conditions,
whereby allowing water to enter the battery compartment.
Dead Batteries should be removed immediately-espe-
cially before storage of the locator. Dead batteries are prone
to leakage and may potentially damage the locator.
Replace all six batteries at once. Never selectively re-
place batteries.
In the event the "Low Battery" indicator is not displayed,
no visual indications appear on the LCD window and no
sound is heard after pressing the power ON Switch-the bat-
teries may be completely dead. Check the battery compart-
ment immediately.
Personal Items: Your magnetic locator is not only sensitive
to buried magnetic objects-it will also respond to items in your
possession. Ferrous objects such as steel tipped shoes, a
pocket knife, some wrist watches, key chains and other mag-
netic objects will cause false signals during your search.
