The GMRS-3000PK has 22 channels (frequencies) indicated by the large digits on the LCD display panel. Channels 1-7 are shared GMRS/FRS channels; channels 8-14 are FRS only channels, while channels 15-22 are assigned GMRS only channels. If an FRS only channel (8-14) has been selected, the HI or LO icon will not be displayed on the LCD panel; otherwise, for channels 1-7 (GMRS/FRS) and 15-22 (GMRS only), the HI or LO icon will be displayed. Communication with Audiovox GMRS/FRS and compatible units is possible on these 22 channels. Before transmitting on the selected channel, press the Monitor (M) Button to check the activity on that channel.
