Putting into operation

For standard underwater use the detector may be used in its short version. For normal
land use or when working in underwater vegetation the extension rod can be fitted to the
threaded end of the detector handle if the slope is inserted into the extension rod.
How to put the detector into operation
ON/OFF
®
Hold UWEX 722 detector at the search head joint and unscrew handle. Insert a fresh
PP3 battery into the battery compartment. Watch polarity, as detector would not work as
long as polarity is inversed. Refit handle to detector without applying force.
To switch detector ON turn handle by 180° in clockwise direction until the white dots at
the handle and at the search head flange are matching and you notice an audio signal in
the single sided headset. To switch it OFF turn half turn in anti-clockwise sense until
and white dot match
Tuning the sensitivity
Release sensitivity control knob at search head joint by anticlockwise rotation. Hold
search head clear from metal. Sliding control knob towards the search head increases
sensitivity, sliding it towards detector handle reduces sensitivity. Maximum sensitivity is
tuned when knob is positioned at a point where the audio signal in the headset is 'just'
suppressed. When search approaches a metal object the detector will start to give an
audio alarm in the headset.
