CTCSS/DCS The dealer can set CTCSS/DCS on the radio channels to ignore calls on the same channel from irrelevant radios. If a channel has been set with CTCSS/DCS, the squelch will be activated only when it receives the proper CTCSS/DCS signals. And only the radios set with the same CTCSS/DCS signaling as those on yours can hear your call. Note: Using a CTCSS/DCS channel doesn’t mean your calls are private. If the CTCSS/DCS tones of other radios are identical with those on yours, they can hear your calls.
PAGE 21
During scanning, if the priority channel has been set on the radio, when the priority channel receives signals the radio will automatically switch to the priority channel even the normal channel is receiving signals at that time.
