NULSTILLING AF DREJESPOLE-INSTRUMENT.
Det kan være nødvendigt at finjustere instrumentets nulpunkt. Det gøres
ved at slukke for metaldetektoren og dreje på skruen lige under
instrumentet med en passende skruetrækker, således at viseren står
præcis i midten (på nul)
HOVEDTELEFON.
Det er muligt at tilslutte en hovedtelefon, dette gøres i den lille jackbøsning
(3,5mm) mærket HEADPHONE. Brug af hovedtelefon forlænger
batteriernes levetid og gør det samtidig lettere at høre mindre variationer i
lyden.
Den indbyggede højttaler kobles fra når hovedtelefon-stikket sættes i.

USING HEADPHONES
You can connect a pair of stereo headphones (not supplied) to the detector
so you can listen to it privately. Using headphones also saves battery power
and makes it easier to identify subtle changes in the sounds you hear, for
better detection results. Your local SkyTronic store has a wide selection of
headphones.
To connect headphones to the detector, insert the headphones’ 1/8-inch
plug into the HEADPHONE jack on the side of the control housing.
The detector’s internal speaker disconnects when you connect
headphones.
Listening Safely
To protect your hearing, follow these guidelines when you use headphones.
♦ Set the volume to the lowest setting before you begin listening. After
you begin listening, adjust the volume to a comfortable level.
♦ Do not listen at extremely high volume levels. Extended high-volume
listening can lead to per-manent hearing loss.
♦ Once you set the volume, do not increase it. Over time, your ears adapt
to the volume level, so a volume level that does not cause discomfort
might still damage your hearing.
Traffic Safety
Do not wear headphones while operating your detector near high-traffic
areas.
Even though some headphones are designed to let you hear some outside
sounds when listening at normal volume levels, they still can present a
traffic hazard.
OPERATION

ferrous metals. Ferrous metals contain. Iron, while non-ferrous metals such
as gold, silver, copper, platinum, aluminum, lead and zinc do not.
