Power Button with Operating LED:
Push the Power Button to switch on the Control Unit. At first,
the Operating LED starts blinking for about 2 seconds before it remains
green
permanently. If
the LED blinks rapidly before turning off, the internal battery is too low and must be charged (see
chapter "4.1 Charging the Control Unit" on page 13).
If you are using Bluetooth Headphones, you see its pairing state by looking at the Operating LED.
If the LED is
blue
the headphones are properly connected and ready to use as output source for
any acoustic signals. More details about Bluetooth Headphones and the LED indications can be
found in chapter "3.4 Bluetooth Headphones" on page 12.
To switch off the Control Unit, push the Power Button for at least 3 seconds until the Operating
LED turns off.
Volume Knob
(black cap): This knob regulates the volume
of the acoustic output. Turning the knob to the left low-
ers the volume, turning it to the right raises the volume.
If the value reaches its minimum or maximum, addition-
al turning in the same direction will have no decreasing
or increasing effect. In this case, you will hear a double
tone that indicates you reached the end of the adjustment
range.
In case you need to connect Bluetooth Headphones, the
Volume Knob can be utilized for pairing purposes. Please
read chapter "Pairing new Bluetooth Headphones" for
more information.
Sensitivity Knob
(gray cap): This knob is used to regulate
the sensitivity of the Search Coil. The higher the sensitivity
the deeper you may find underground objects but the more
noise and disturbances you may receive alongside metal
signals.
Turning the knob to the left lowers the sensitivity, turning
it to the right raises the sensitivity. If the value reaches
its minimum or maximum, additional turning in the same
direction will have no decreasing or increasing effect. In
this case, you will hear a double tone that indicates you
reached the end of the adjustment range.
If the sound output gets to noisy, you may apply a ground
balance by pushing the Sensitivity Knob downwards. Read
chapter "Ground Balancing" for more details about bal-
ancing your metal detector.
