Power signals:- radiated by loaded, unbalanced cables.
These signals are also found on other nearby conductors
that 're-radiate' the power signal.
Radio signals:- originate from distant radio transmitters.
These penetrate the ground and are re-radiated by buried
conductors. However, they are not always present.
Genny signals:- present on buried conductors that have had
a Genny signal applied. There are various ways of applying
the Genny signal (see Locating with the C.A.T

Turn Function Switch to A (AvoidanceScan

area for conductors radiating Power, Radio or Genny signals.
In this mode the depth button will not be active (CAT+)
