The GNS 480 provides an internal COM transceiver that can be interfaced to an audio panel or connected
directly to a speaker. The PTT input is used to enable the Com MIC audio and cause the Com
transceiver to transmit on the active frequency. Optional external inputs are available to allow the user to
toggle the active and standby Com frequencies, and select Com frequencies from a user-defined
frequency list.
Refer to Appendix D for interconnect information.
Refer to section 3.2.1.5 for information on setting the RF squelch and mic gain values.
