MMSI NUMBER

When you power up your radio for the first time, MMSI Not Entered appears, followed by a Marine mode screen. To use DSC features, you must be assigned an individual User MMSI number and program that number into your radio. User MMSI numbers are unique and cannot be entered more than once.  If you choose to not enter your specific MMSI number at the initial start-up, you can still use many of your radio’s features. However, some radio functions will be impacted, and you will not be able to use any DSC features.

You can get more information on MMSI numbers at these resources:

  • The dealer where you purchased the radio
  • Recreational boaters can obtain an individual MMSI number from the Boat Owner’s Association of the U.S. (BoatUS or call 800-563-1536) or SeaTow Services International  https://seatow.com/
  • Commercial boaters need a ship station license to get an MMSI number. For more information, visit the Federal Communications Commission (FCC) website at http:// wireless.fcc.gov/marine/ fctsht14.html.

Tip:
Before you begin this process, have your MMSI number available and familiarize yourself with the menu navigation on Page 10. Be sure you have the correct User MMSI number before entering it in the radio. The radio only allows you to enter the User MMSI once. If you need to re-enter the User MMSI number, visit support uniden for assistance.

OPERATING THE RADIO

To customize your radio to your specific needs, it is important to understand its basic operation. Your radio has three main operation modes:

UM725GBT Marine VHF Radio 28

DIGITAL SELECTIVE CALLING (DSC)

WHAT IS DSC?
Digital Selective Calling (DSC) is a standard that allows you to quickly and easily call specific radios or groups of radios using their unique MMSI (Maritime Mobile Service Identity) number. The four basic call types are:

  • Distress Calls – Use in emergencies only! The Distress message alerts all ships that you need assistance and sends your current position.
  • Individual Calls – Calls a single station using the User MMSI. Use when you want to talk to another station
  • Group Calls – Calls all ships with the same Group MMSI. Use it to talk with your whole group at the same time.
  • All Ships Calls – Calls all ships within range of your radio. Should.

HOW DOES DSC WORK?
The DSC standard dedicates a VHF channel—channel 70—to digital transmissions only. Because digital transmissions require less bandwidth than voice transmissions, channel 70 avoids the problems of busy voice channels. The radio uses channel 70 to transmit your MMSI number to the other station along with a voice channel. If the other station accepts your call, both radios automatically switch to the requested voice channel so you can talk to the other station.

DSC also provides a system for automated distress calls. At the touch of a key, the radio can transmit your MMSI number, the nature of your distress, and your current position based on data from your GPS receiver. The radio repeats the distress call every few minutes until it receives an acknowledgment. Much like familiar “contacts” and “group text” functions of modern phones, your UM725 lets you save individual contacts in your Individual Directory and groups in your Group Directory.

Suppose you are coordinating safety for a sailboat race. Before the race starts, you instruct all the racers to enter your group MMSI number into their radios. During the race:

  • Throughout the race, you use group calling to update the racers on the time, race status, and any course corrections.
  • A powerboat full of spectators comes too close to the race path. You use individual calling to contact the power boat and advise them to stay clear of the race.
  • You see a rowboat entering the area, but since it doesn’t have a radio, you can’t communicate with the rowboat. You use all ships calling to alert all the other ships in the area of the possible danger.

Note:
Automatic acknowledgment automatically transmits your current position in response to position requests. Most boaters activate automatic position replies for safety reasons or because they subscribe to a marine towing service. Sometimes—for example, in some competitive situations—you may not want other ships to get your position without your manual confirmation.

SETTING UP DSC INDIVIDUALS AND GROUPS
Much like traditional contacts in a phone, DSC directories let you store up to 100 individual MMSI numbers of other ships and 50 group MMSI numbers. From the directories, you can add, edit, or delete MMSI numbers.

TO MANAGE A GROUP DIRECTORY

Unlike the user MMSI number, you can create a group MMSI number yourself, and You can also change the group MMSI number as often as you want. You don’t have to get a group MMSI number from a specific organization. For example, if you are part of a boating club,

Note:
To modify an existing group, press EDIT in Step 3 and select the group name from the list that appears. To delete a group from your directory, select DELETE, select the group, and then confirm.

NAVIGATION

WAYPOINTS AND ROUTES
You can search the internet for latitude and longitude for the location you want. For example, search for “Key West Naval Hospital coordinates.” You can save up to 250 waypoints in your Waypoint Directory. You can also use the position stored in MK POS and MOB.

Note:
The Waypoint selected for the 01 position will be the first point to which your radio will navigate. When you reach that waypoint, the radio will navigate to the next waypoint (02), and continue through the list of waypoints.

BASIC RADIO GUIDELINES
You should familiarize yourself with the rules on marine radios and be aware of which rules apply to your ship. Complete guidelines for all ship and marine radio types can be found at the US Coast Guard website under the topic Radio Info for Boaters (the direct link is http://www.navcen.uscg.gov/?pageName=mtBoater. Here are a few guidelines that affect nearly all boaters.

  • If you have a VHF radio on your ship, you must maintain a watch on channel 16 (156.800 MHz) whenever the radio is not being used to communicate. Starting in 2004, if a radio is carried, it must be on and set to channel 16 whenever your ship is underway.
  • If you hear a distress call, wait a few minutes to let a shore station or Coast Guard ship respond. If no other station has responded after 5 minutes, you must respond to the distress call.
  • Do not make false mayday or distress calls as a prank or to test your radio. (This is essentially like making a false 9-1-1 call; you may be subject to fines.)
