OPERATION
Turn the detector on by setting the power switch to
the forward or back on position. The green alert light
will illuminate and an audio alert or brief vibration will
indicate the unit has been turned on. The green alert
light will remain on until the unit is turned off.
When the detector is operating, it will detect metal
only while it is in motion. Move the instrument within
approximately one inch from the person (object) being
inspected. A sound will be heard or vibration felt and the
red alert light will illuminate whenever metal is detected.
Operation is completely automatic. No "retuning" is
ever necessary. All conductive metals will be detected,
including ferrous, non-ferrous and stainless steel.
Audible Operation
– Press the power switch forward and
a clear alert signal will be heard, either through the
speaker or through an optional earphone, whenever
the metal detector detects metal. The forward-most red
alert light will also appear upon detection of metal.
Silent Vibrating Operation –
Press the power switch
backward and the detector handle will vibrate whenever
metal is detected, but no sound will be heard. The red
alert light will always appear upon detection of metal.
NOTE: Do not affix metallic labels (or any
material that might cause the detector to
alarm) to the detection area of the metal
detector. Doing so might cause an imbalance
within the detection field and thereby reduce
scanning effectiveness.
SERVICE
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 metal detector is to be stored more than
30 days, remove the battery.
INTERNAL SENSITIVITY ADJUSTMENT
Some applications may require a sensitivity setting other
than the nominal factory setting. This may be achieved
by choosing an appropriate test target and utilizing the
internal sensitivity adjustment as follows:
Turn on the metal detector. Roll back the grip cover
just below the nameplate. Insert a small flat or
Phillips screwdriver into the potentiometer located
within the exposed hole. Rotate the potentiometer
counterclockwise to decrease sensitivity, or rotate the
potentiometer clockwise to increase sensitivity, until the
desired detection of the test target is achieved.
An excessive sensitivity setting may result in unstable
operation (chatter) and excessive detection of
surrounding metal.
NOTE: This sensitivity adjustment potentiometer
is set to the nominal center (12 o'clock) position
by the manufacturer.
CAUTION! Always verify that the detector is set
to the desired sensitivity level by testing with
appropriate targets any time the sensitivity
adjustment is changed.
