Appendix B – Mode 2 Operation
Overview
The C-5000 has the capability to control the RT-5000 in such a way that the user can monitor both the
main and the Guard (ITM) channel at the same time. This mode of operation is more difficult to use than
MODE 1.
The Home Page
The only visible difference in the HOME PAGE from Mode 1 operation is in the Main/Guard status fields.
The illustration below depicts the HOME PAGE for a system comprised of two digital RT-5000 radios.
Both radios are configured to operate in Mode 2. The Main transceiver is the active transceiver on radio
1. The digital transceiver (Guard) is the active transceiver on radio 2. The active transceiver is the one
that will transmit when the push-to-talk switch is depressed.
