Conventional Channels
If your radio is programmed for Talkback Scan, pressing PTT while a channel is 

active during the scan delay time remains, will cause the radio to transmit on the 

transmit frequency of the received channel. The "RX" indicator will be shown in the 

display while scan delay time remains.
Talkback Scan will not work if Priority Scan is on and your radio is also programmed 

to transmit on the Priority 1 channel. (See Priority Scan.)

Conventional and Trunking Channels
Dual Mode scan provides the ability to scan trunking and conventional channels 

simultaneously. 
When Dual Mode Scan is turned on the 

 icon is displayed and the radio scans all 

channels in the dual mode scan list.
Dual Mode Scan can be assigned to a button or menu list item. For best operation, 

Dual Mode Scan should be assigned in both conventional and trunking global 

settings with the PC Radio Editor.
