device. Getting started remove from the your pockets and outfit any
items that contains semi-conductive components.
Carry out searching operation with maximal receiver sensitivity.
Use ATT button to activate this mode (see fig. 10 for reference).
The receivers sensitivity is determined by real noise environment
situation right on spot, for instance, by extraneous emission activity
and/or non-lineal junctions that cannot be removed from the area
under control.
