Chapter 2 APX Mobile Dual-Radio Operation
2.1
Overview
The APX Dual-Radio contains two APX Mobile radios, single O7 Control Head, two speakers, and
associated cabling (see
control two radios. One radio is designated as the Primary Radio, while the other is designated as
the Secondary Radio.
Only one radio is accessible from the control head at any one time. The accessible radio is referred
to as the Selected Radio, while the other radio is referred to as the Unselected Radio. The O7
Control Head indicators and display always reflect the state of the Selected Radio. In general, button
presses like Push-to-Talk (PTT) only affect the Selected Radio, unless otherwise noted throughout
this document. The Unselected Radio is normally in the receive, scan, or emergency state.
Customers connect the two APX Mobile radios to each other via a short CAN cable, and connect an
O7 Control Head to one of the radios.
One speaker connects to the O7 Control Head and plays audio from the Primary Radio, and another
speaker connects to the Secondary transceiver via a speaker extension cable and plays audio from
the Secondary Radio.
