Basic Operation
This section covers the fundamentals of PX3
operation. Once you're familiar with the PX3,
please go on to Advanced Operating Features
(page 17).
Using Tap/Hold Switches
Most PX3 switches have two options. Tapping
(pressing for less than 1/2 second) activates the
function labeled in white on the switch. Holding
(pressing for more than 1/2 second) activates the
function labeled in yellow below the switch.
Initial Power-Up

Figure 2 on page 8 or Figure 3 on page 9.

see a spectrum or combined spectrum and
waterfall display. If a KX3 is connected via the

frequency at the top center of the display.
