WARNING
The DSC (Digital Selective Calling) system is a protocol applied all over
the world that uses channel 70 (156.525 MHz) to send and receive
digital messages. The communications take place between VHF radios
equipped with DSC system and are programmed for emergency calls,
individual or collective. The users of VHF DSC radio can contact other
ships equipped with DSC system, avoiding unnecessary radio traffic
and improving the communications from ship to ship.

WARNING
For channel selection or special function instructions, please refer to the
radiotelephone Manufacturer’s manual.
S
CAUTION
The DSC-call should only be performed if the yacht is in a real distress
situation. Otherwise, to send a DSC-call with no need is considered as
an infringement.
