Channel Selection In order to communicate with other GMRS/FRS units, both transmitting and receiving party must be on the same frequency. The GMRS122-2CH has 22 channels (frequencies) (1-22) indicated by the large digits on the LCD display panel. Channels 1 through 7 are the shared GMRS/FRS channels. Channels 8-14 are FRS only channels,while channels 15-22 are assigned GMRS only channels.
To change the CTCSS Sub-channel, - From GMRS/FRS standby mode, press the MODE twice; a flashing oF or sub-channel number is displayed. - Press the Up or Down button to select the desired sub-channel for use (1-38). - Press the PTT or Power On/Off button to confirm selection. The CTCSS mode can be turned off by selecting the oF icon as the setting. NOTE: To communicate with other GMRS/FRS units, they must be switched to the same channel and CTCSS subcode.
