SERVICE INFORMATION
Battery Replacement
Slide back the battery cover (do not
attempt to remove it), tilt the detector and
battery will slip out. Replace with fresh
battery. Because the battery cover will
not slide back if the battery is inserted
improperly, never force the cover. When
the SuperScanner is to be stored more
than 30 days, remove the battery.
Threshold Adjustment - Turn on the
SuperScanner. Roll back the grip cover
just below the nameplate. Insert a small
flat blade screwdriver in the exposed
hole and turn slightly to adjust. Sound
should be barely silent when the detector
is tuned on but not detecting metal.
Maximum sensitivity is achieved when
threshold is set just below audible level.
A decrease in sensitivity can be achieved
by further rotation.
