ADVANCED FEATURES
CTCSS
➤ Continuous Tone Coded Squelch System (CTCSS) is a feature that allows a
group to talk to each other without hearing other users on the same
channel.
Uniden discourages the use of CTCSS feature until the Australian
Communications Authority (ACA) grants the use of CTCSS on CB
frequencies.
VOX
➤ Built-in Voice Activated Circuit (VOX) feature enables the user to
transmit automatically by speaking on the microphone of the VOX headset
(not supplied) without pressing the PTT switch.
