Even though some earphones are designed to let you hear some outside
sounds when listening at normal volume levels, they still can present a
traffic hazard.
OPERATION
Your SkyTronic Metal Detector distinguishes between ferrous and
nonferrous metals. Ferrous metals contain iron, while non-ferrous metals
such as gold, silver, copper, platinum, aluminum, lead, and zinc do not.
When the detector senses a metallic object, the meter reading changes and
the detector might sound a tone. The actual reaction depends on what
metal is detected.
PREPARING THE DETECTOR
Turning On the Detector
Hold the detector in a comfortable position, then rotate VOLUME away from OFF to the
desired sound level. Set OPERATE/BATT TEST to OPERATE to detect.
Tuning the Detector
TUNE fine-tunes the balance between the detector’s receiver and
transmitter circuitry to provide consistent pointer and tone indications.
Follow these steps to set TUNE.
1. Rotate VOLUME to the 11 o’clock position.
2. Set DISCRIMINATION to its midpoint.
3. Hold the search coil about 1 foot away from the ground and any metal
object, hold down the red button on the handle, and slowly rotate TUNE
left and right until the pointer on the viewmeter rests at or near 0, then
release the red button.

ISÆTNING AF BATTERIER.
Der skal bruges 6 stk penlight (AA) batterier. Brug altid batterier af god
kvalitet evt. genopladelige. De 6 batterier SKAL desuden være af samme
slags.
5. Drej volumeknappen helt mod venstre (OFF).
6. Fjern batteridækslet.
7. Placer batterierne i henhold til den viste polaritet.
8. Sæt dækslet på igen.
HUSK! Hvis metaldetektoren skal henligge i længere tid uden at blive brugt,
bør batterierne fjernes.
BATTERITEST.
Hvis metaldetektoren ikke længere virker optimalt og lyden er lav/dårlig er
det fordi batterierne skal udskiftes. Batterierne kan testes på følgende
måde.
