6 USE WITH GPS
6.1 Function
If connected to a GPS receiver, the transceiver will display the vessel position
(latitude and longitude), as well as time data. If information regarding position data
are not received, in the normal radio mode, time data does not appear and a minute-
long warning tone will sound (can be deactivated by pressing any button). This tone
will sound every 4 hours, reminding the user that position data needs to be inserted.
The user may also insert the coordinates manually as described in par. 9.6.
6.2 GPS information on the display
Refer to the following illustrations:
1. Position indicator
Displays GPS or manually inserted co-ordinates.
2. Time indicator
Shows data supplied by the GPS or the transceiver’s clock.
6.3 Customized setup
Some GPS receivers may require a change in the manner the radio processes the
GPS data. Pressing GPS selection diplays CHECKSUM ON/OFF selection.
If no GPS receiver is connected, using WARN BEEP ON/OFF allows the user to
defeat the audible warning that new position data is required. Press C button to
return to menu. Display On/Off button controls the presence of the automatic display
announcing that the position data is over 4 hours old.
7 DIGITAL SELECTIVE CALLING (DSC)
7.1 Introduction
Digital Selective Calling is a semiautomatic method for controlling VHF, MF and HF
radio calls. It was also designed as part of the global marine security and
emergency response system (GMDSS). It is likely that DSC will eventually replace
audio calls on emergency frequencies and will be used to send urgent and routine
radio-transmitted maritime security information. This new service will allow crafts to
send/receive calls of an emergency, urgent, security, or routine nature to/from
vessels equipped with a DSC transceiver.
, To avoid accidentally sending a distress call or a call sent incorrectly, contact your
vendor or local authorities for updates on DSC operating and emergency
procedures.
, In European inland waterways DSC-function is not allowed.
7.2 Mobile Marine Identification Service (MMSI)
Important! To send/receive DSC calls, the user must program his personal MMSI code
into the transceiver. This is a nine-digit number used by marine transceivers equipped for
DSC digital selective calling. This number is used much like a telephone number for
contacting other, specific vessels. For further details on programming your MMSI, see
par. 9.10.
7.3 Navigating the DSC menu
REGATTA 2 offers many DSC functions. For this reason it was created a specific
menu of settings and activations accessible via the function keys as follows:
1. Access the “CALL”-Menu by pressing the related function key.
2. Press the function key corresponding to the word “Type” to select
the type of desired call.
Once inside a sub-menu, you can return at any time to the main menu by pressing the C-
button and terminating the current operation.
7.4 Individual call (Routine To)
The user can carry out an individual call to a specific DSC station (a vessel or a
costal station). To carry out calls, you have to enter the MMSI code manually or
recall it from the pre-programmed MMSI directory. For further details on
programming the MMSI directory, see par. 9.5.
