CTCSS/DCS (CTC/DCS)
There are two types of tone offered; CTCSS abbreviated CTC and DCS.
Both these tones work in conjunction with the channel to prevent
interference from other users who may be working on the same channel.
To change the CTC or DCS tone press "FCN" once, the CTC/DCS display
will flash. Use the up/down keys to select the CTC/DCS tone you require
and press the "ENTER" key to save your setting. DCS tones are located
after CTCSS 38.
Note : If two groups are communicating within range of each other using the same
channel, despite using different tone codes only one group can use the same
channel at any one time. When the channel is being used by a different group
the green LED will flash, but no speech will be heard from the speaker.
If using this feature please ensure that all users in the system have the
same tone code programmed.
