CTCSS/DCS
Your ALAN HP 446 extrá can operate in two modalities:
• OPEN CHANNEL : all signals transmitted on the selected channel will be
heard. The status LED will glow green.
• GROUP MODALITY CTCSS/DCS: CTCSS and DCS tones are “access
tones” that allow you to receive only calls from parties using same chan-
nel and code.
The status LED will glow green when signals with the correct
CTCSS/DCS code are received, it will glow amber if signals with the
incorrect CTCSS/DCS code are received.
