11. Operation

a) Functions and display

Push button (reset) (7)
TUNE dial (9)
VOLUME dial
DISC dial (15)
LED battery indicator (11)
Analogue display (12)
Speaker (13)
Headphone socket (14)
b) Switching on and off
• Turn the VOLUME dial (10) clockwise to switch on the metal detector. The metal detector switches on when the dial
clicks into place. When you start searching for metals, move the dial to the fourth point on the scale.
Do not move the dial to the maximum position, otherwise the metal detector will beep continuously at a
high volume.
• Turn the VOLUME dial (10) anticlockwise to switch off the metal detector. The metal detector switches off when the
dial clicks into place in the "OFF" position. The LED battery indicator (11) will briefly switch on and off.

c) Basic setting - TUNE

This setting needs to be configured to ensure that the metal detector gives consistent results and to prevent
interference or false signals. The metal detector should be retuned each time it is switched on.
• Keep the detection probe (1) away from metal objects and other overground sources of interference (e.g. fluorescent
tubes). Keep the search probe (1) at least 30 cm above the ground and hold it in an open space.
• Turn the VOLUME dial (10) clockwise to switch on the metal detector.
• Turn the VOLUME dial (10) clockwise to 11 o'clock.
• Turn the DISC dial (15) to the centre position.
• Press and hold the push button (7) on the handle with your finger and slowly turn the TUNE dial (9) clockwise until
the pointer on the analogue display (12) points to zero. If necessary, move the dial backwards and forwards slightly
until you find the correct position.

Together with the TUNE dial (9), this push button is designed to configure/
adjust the zero position of the display pointer.
Together with the push button, the TUNE dial (7) is designed to configure/
adjust the zero position of the display pointer.
This dial (together with the DISC (15) and TUNE (9) dials) is used to balance
the internal electronics and the search probe (1). This setting affects the
volume of the signal played by the speaker (13) and the headphones in an
indirect, non-linear way. Turn the dial until the signal is barely audible in the
default setting.
Configures the metal discrimination of the detection probe (1). The metal
discrimination setting also affects the sensitivity of the metal detector.
Turns on when the battery voltage is low (< 7 V/DC).
Displays the approximate material type (right = non-ferrous metal, left = steel/
iron)
Audio signals
Connect a suitable headset to the 3.5 mm jack socket. The speaker (13) will
switch off automatically.
