Calls to other ships

To call another ship or a coast station, you simply enter their dedicated Maritime
Mobile Service Identity (MMSI) number, select your chosen VHF working channel
and send the call - it's like using a telephone. Both your radio and the one you are
calling automatically switch to the chosen channel for conversation.

Group calls

When groups of ships need the same information (yacht races, club rallies etc.) a
special group-call identity can be used to enable restricted broadcast messages.

Safety broadcasts

Safety broadcasts from coast stations and other shipping automatically generate
an alert (ring tone) to ensure that this vital information is not missed.

Distress alerts

At the touch of a button, you can send your ships identity, your position and the
nature of your distress. The position given will be precise and the alert will be
heard immediately by all DSC equipped vessels and coast stations within range.
The message is automatically repeated at approximately 4 minute intervals until
it is acknowledged either by a coast station or a vessel within radio range.
To transmit precise positions, the radio must be interfaced to your Global
Note:
Positioning System (GPS). Otherwise, regular manual position updating is required.
1.3 Can I use the Ray240 as part of an integrated
system?
Your Ray240 can receive position information, e.g. latitude and longitude, using
either of the following protocols:
• National Maritime Electronics Association (NMEA) 0183.
• SeaTalk
enabling DSC integration with other instruments.
You can also add an additional handset and active speaker to the standard
Ray240, giving two fully functional stations with an intercom function. This is
particularly useful where your boat has dual helms or a second navigation station.
