Selecting the channel

The PT-1016 is pre-programmed with 16 channels. It is recommended to use the first eight
channels (1..8) as these are a combination of a radio frequency combined with a DCS sub-
channel code. This way, there will be less interference of other PMR 446MHz users on your
channel.Last eight channels (9..16) are the eight different radio frequencies and will allow you to
speak/listen to users who are using PMR 446 MHz radio's that are not using sub-channel codes.
