Midland Radio RG2B, RG2W manual USE with GPS, Digital Selective Calling DSC

7 USE WITH GPS

7.1Function

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. 10.6.

7.2GPS 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.

7.3Customized 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.

8 DIGITAL SELECTIVE CALLING (DSC)

8.1Introduction

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.

ITo 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.

IIn European inland waterways DSC-function is not allowed.

8.2Mobile Marine Identification Service (MMSI)

2Important! 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. 10.10.

8.3Navigating 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.

2Once inside a sub-menu, you can return at any time to the main menu by pressing the C- button and terminating the current operation.

8.4Individual 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 preprogramed MMSI directory. For further details on programming the MMSI directory, see par. 10.5.
