Power On/Off Tune Switch (1)
This rotary control switches the detector on and adjusts the level of audio tune to the
user’s preference and the level of meter tune when in the Manual Control modes (see
below).
Sensitivity/Battery Check (2)
In the fully anticlockwise switched position the Battery Check is enabled with the battery
condition displayed on the meter (8).
When turned clockwise the control will adjust the sensitivity of the detector to metal
objects.
By increasing the sensitivity by tuning this control clockwise, the detector will be more
prone to drift, erratic signals, ground interference etc. Where there is no ground effect or
outside interference the SENSITIVITY control can be operated at higher levels.
When the signal becomes unsteady or erratic, the sensitivity level should be reduced to
obtain a clear, steady tuning threshold. Only when the tuning is constant and steady will
the detector operate at the optimum depth penetration.
The recommended starting point is midway, i.e. “12 O’clock” position.
