Channel and Sub Codes
• You must set your radios with the same channel and sub code setting to enable communication
with other radios.
• The channel setting controls the radio frequency. To avoid jamming, you can select a channel that
is not used by others in your area. For more information on selecting unused channel, see Scan on
page 21.
• Match the sub code setting on the transmitting and receiving radios. Otherwise, the receiving radio
blocks the received signals. This feature helps you to mute unwanted voices from other radio users
transmitting on your channel.
• When sub code is set to zero, radio does not block any signals. Everything that is picked up on
the channel is sent to the speaker. Motorola Solutions recommends setting your sub code to zero if
you are using T600 series radios with radios that do not support the sub code feature. For detailed
instructions on ways to change settings, see Navigating the Menu Pages on page 16 .
• You can copy channel and sub code settings from one radio to multiple radios simultaneously with
the Easy Pairing feature. For ways to copy channel and sub code settings, see Radio Overview on
page 9.
