About Digital Selective Calling

Digital Selective Calling

DSC is a technique used by marine radio systems to augment calling the another station by voice. It permits other vessels to be called up by keying in a unique identity number known as the MMSI. It also provides a button that will generate a distress alert identifying the vessel in distress, the nature of the problem and a position derived from an installed, optional Global Positioning Satellite (GPS) device.

The feature was implemented in February 1999 as an integral part of the Global Maritime Distress and Safety System (GMDSS).

Digital Selective Calling (DSC) lets mariners instantly send automatically formatted distress alerts to rescue authorities anywhere in the world. Digital selective calling also lets mariners initiate or receive distress, urgency, safety and routine radiotelephone calls to or from any similarly equipped vessel or shore station, without requiring either party to be near a radio loudspeaker. DSC acts like the dial and bell of a telephone, allowing you to “direct dial” and “ring” other radios, or allow others to “ring” you, without having to listen to a speaker.

Your radio's DSC Call feature lets you transmit and receive DSC Calls based on ITU-R M.493-11. For a detailed discussion of this standard, you can refer to the following web site document: http://www.gmdss.com.au/ITU%20DSC%20tech%20spec.pdf and read a full explanation on line.

If you have an optional GPS installed, you can send a distress message in an emergency situation which includes your position. You can also send and receive position data to and from other vessels. Additionally, you can set up and use a directory of other vessels with DSC radios.

The radio's NMEA input and output feature lets you display and use vessel

information. When equipped with an optional GPS, the UM625c can send and receive DSC calls that include the following information: distress, individual, individual ack(nowledgement), all ships, group, position request, position reply, and position send. DSC calls to your radio can receive include distress ack, geographic, distress relay, and distress relay ack.

Mobile Maritime Service Identity (MMSI)

This refers to a unique nine digit identification number designated for each qualified vessel or shore station. It is in a way, a maritime equivalent of a telephone number. You must obtain your personal MMSI before you can program and or transmit data mentioned above. If you have access to the web, open either http://www.boatus.com and navigate to the convenient MMSI application form provided. Or, go to http://www.seatow/boatingsafety/mmsi/mmsiRegister.asp and complete the on-line form provided. If you do not have web access, you can call, toll free, BoatUS, in Alexandra, VA at 1-800 563-1536 and request that the MMSI form be mailed or faxed to you. This presumes you use a recreational vessel in domestic U.S. waters and that you are not otherwise required to be licensed. Because BoatUS is set up to take advantage of an electronic registration system, using standard mail or fax will be much slower. You can also call the FCC Forms Distribution Center at 1-800 418-3676 who then will provide you with the form types they require.

Understanding Your Radio

About This Manual

The screen displays used in this manual are representations of what might appear when you use your radio. Since what you see depends on the frequencies for your area and the settings you select, you might notice some differences between what is in this manual and what appears on your radio's display. Buttons you press appear in BOLD type, icons that

appear on the display appear in BOLD REVERSED type, and text that appears on the display appears in italic type.

How The Radio’s Controls Appear in This Manual

To help navigate the radio's menus, the steps shown in this manual describe the displays you see and the keys you press or control you operate to get a desired result.

This example shows you how to use the radio's menu to program a user MMSI for the first time. The MMSI is a unique nine digit identification number allocated to each vessel or shore

station. It is analagous to a normal telephone number. This example shows you the button to press (PUSH/SELECT) to view a series of choices, the control to use (PUSH/SELECT) to view and select more choices, and the correct options to select (SETUP and USER MMSI) as you rotate PUSH/SELECT. It also instructs you to press PUSH/SELECT to select the options.

Important: If you have already set the user MMSI, DO NOT CHANGE IT unless you have received a new user MMSI. After you program a user MMSI for the first time, you can only change it once more. If you try to change the user MMSI a third time, the radio will not accept the change. To change the user MMSI again, you must

return the radio to Uniden for reprogramming.

1.Quickly press and release PUSH/SELECT. A screen appears containing options you can select to work with the radio's

features.

2. Rotate PUSH/SELECT to select SET UP, then press

PUSH/SELECT to select it.

3.Press PUSH/SELECT to select INITIALIZE.

4.Rotate PUSH/SELECT to select USER MMSI, then press PUSH/SELECT to select it.

If a user MMSI has already been programmed once or twice, it appears on the screen.

Stop here.

Understanding Your Radio

Otherwise, if a user MMSI has not been programmed, the first digit of the blank user MMSI flashes.

5.To enter the first digit of the user MMSI, rotate PUSH/SELECT until the digit appears, then press PUSH/SELECT. The digit you entered appears on the display and the flashing cursor moves to the next position.

6.Repeat Step 5 for each of the user MMSI's digits.

7.If the displayed user MMSI is correct, rotate PUSH/SELECT to select YES, then press PUSH/SELECT again to confirm it. The setup menu appears.

If the displayed user MMSI is not correct, rotate PUSH/SELECT to select NO, then press PUSH/SELECT to confirm it. Then repeat Steps 4 through 6 to enter the correct user MMSI.

If you are new to using a marine radio, be sure to read “About Digital Selective Calling” on Page 5 for a quick DSC technology background. First you need to connect an antenna and power to the radio. Then you need to install the radio aboard your vessel. For help with this operation, see “Connecting the Antenna” on Page 13, “Connecting Power” on Page 13, and “Installation” on Page 13.

Setting Up The Radio

Connecting the Antenna

Your UM625c has been designed to accommodate all of the popular marine VHF antennas. However, the selection and the installation of the antenna is the responsibility of the user or installer. A variety of antennas are available from a number of quality suppliers. In general, we recommend an 8' antenna rated at 6dB for powerboats, and a 4' antenna rated at 3dB for sailboats.

In general, you can increase your communication range by using a high-gain antenna placed as high as possible above the water line. Locate the antenna away from metal objects. Keep coax feed cables as short as practical.

The FCC has determined that excessive radiation poses a health risk to people near radio transmitting antennas. Therefore, the antenna used with this radio should be installed using the following guidelines to ensure a suitable distance between the antenna and persons close by.

•Small whip antennas (3 dB or smaller) should be installed keeping at least 3 feet separation distance between the radiating element and people.

•Larger antennas (6 dB or 9 dB) should be installed with at least a 6 feet separation distance.

•No person should touch the antenna or come closer than the separation distance when the radio is transmitting.

To connect the antenna to the radio, screw its connector onto the antenna jack on the back of the radio.

Connecting Power

1.Connect the red wire of the supplied power cord to the positive (+) side of your distribution circuit or battery.

2.Connect the black wire of the supplied power cord to the negative (-) side of your distribution circuit or battery.

Note: The power cord is equipped with a fuse to protect the radio. Use only a six (6) amp fast blow fuse for replacement.

3.Connect the power cord to the keyed connector on the power “pigtail”.

Installation

Caution: The UM625c is designed to use a nominal 13.8 volt negative ground battery system for power. Do not use a positive ground battery system to power the UM625c.

Keep in mind the flexibility designed into the UM625c so that you can most conveniently use it. Features which should be considered are:

•The universal mounting bracket may be installed on either the top or bottom of a shelf, on a bulkhead, or for overhead mounting.

Setting Up The Radio

13

•The remote speaker wires can be used with an auxiliary speaker.

•All connections are “plug-in” type for easy removal of the radio.

•By using an optional WHAM or WHAM x 4 (Wireless Handheld Access Microphone), the UM625c can be mounted completely out of the way.

•An accessory flush mount bracket (FMB321) is optional.

Choosing a Location

Here are some important factors to consider in selecting the location for your UM625c.

•While the UM625c is completely waterproof, it will last longer if protected from spray and splash.

•Connect the UM625c directly to the battery for best operation. Always keep the battery leads as short as possible. If a direct connection can not be made with the supplied power lead, any extension should be made using #12-14 AWG wire. Use larger gauge wire for longer extensions.

•Keep the antenna lead-in wire as short as possible. If you must use a long lead-in wire as in the case of a sailboat masthead antenna installation, we recommend you upgrade your lead-in wire according to the following table:

Use RG-58 for distances less than 20 feet.

Use RG-8X for distances less than 35 feet.

Use RG-8U for distances less than 60 feet.

•Locate your antenna as high as possible and clear of metal objects. The reliable coverage range is a direct function of the antenna height.

•Select a location that allows free air flow around the heat sink on the rear of the radio.

•Select a location well away from the ship's compass. Auxiliary speakers also should be located away from the compass.

Engine Noise Suppression

Interference from the noise generated by the electrical systems of engines can sometimes be a problem with radios. The UM625c has been designed to be essentially impervious to ignition and alternator noise. However, in some installations it may be necessary to take

measures to further reduce the effect of noise interference. The UM625c radio DC battery wires, antenna lead, and accessory cables should be routed away from the engine and engine compartment, and from power cabling carrying high currents. In severe cases of noise interference, it may be necessary to install a noise suppression kit. Contact the dealer from whom you purchased the radio for more information.

Installing the Radio

After you have carefully considered the various factors affecting your choice of location, follow these steps to install the radio.

1.Position the radio (with the bracket, microphone, power cord, antenna and any auxiliary cables installed) into the selected location to assure there is no interference with the surrounding items.

14	Setting Up The Radio

2.Mark the location of the mounting bracket.

3.Remove the bracket from the radio. Then use the bracket as a template to mark the holes to be drilled for the mounting hardware.

4.Drill the holes and mount the bracket with hardware compatible with the material of the mounting surface.

Note: Do not use mounting knobs other than the ones supplied. Do not insert the knobs without attaching the bracket.

5.Connect all other auxiliary cables and accessories.

Important: Do not remove the protective rubber cover from any of the connectors on the back of the radio unless you are connecting another cable to them. These rubber covers are designed to prevent water from entering the radio.

6.Install the radio in the mounting bracket and connect all cables and accessories to the appropriate jacks and connectors.

Using a WHAM or WHAM x 4 Microphone With the Radio

To connect a WHAM or WHAM x 4 microphone to the radio, follow the steps listed in “Using the WHAM and WHAM x 4 Sub Menus” on Page 41. Then, follow the steps listed in “Setting a WHAM Base ID” on Page 42, and “Changing the Radio Link Channel for a WHAM x 4” on Page 42. Otherwise, if you are connecting a WHAM x 4 microphone, follow the steps listed in “Setting a WHAM x 4 Base ID” on Page 41, “Setting the WHAM x 4 Sub Radio Mode” on Page 41, and “Changing the Radio Link Channel for a WHAM x 4” on Page 42. Then refer to the owners manual provided with the WHAM or WHAM x 4 microphone for more information about connecting it to the radio.

Important: If you want to use an external antenna for your WHAM x 4 with your UM625c marine radio, it must be installed by a professional installer. Do not attempt to connect an external antenna to a radio yourself.

Note: You cannot use a WHAM or WHAM x 4 wireless microphone to set the user MMSI, WHAM setup, system setup, or self test on the radio. You cannot use a WHAM wireless microphone to use the scrambler, intercom, GPS display, channel tag, or status message display on the radio.

Using One or Two Hailer Horns With the Radio

Connect one or two hailer horns to the radio as shown in “Hailer Connector/Cable” on Page 12. Then follow the steps listed in “Using Hail” on Page 20.

Note: The hailer horns you connect to the radio should have a rated power output of at least 35 Watts and an impedance of 2 ohms.

You can access each of the main screens by applying power, waiting about 4 seconds, then pressing the PUSH/SELECT control once to reach the menu selector screen. Rotate the PUSH/SELECT control until you see the desired screen highlighted. Then press the control to bring up the screen. The examples shown presume that you have connected an optional GPS unit.

The RADIO screen (1) displays the selected channel and the channel name as well as other data you can select during setup. In this example, channel 16 is the Coast Guard/Distress/Hailing channel.

The XTRACK screen (2) displays direction, and bearing as well as Estimated Time Enroute if you have received a Distress, a position send from another vessel, or a position reply. The scale at the bottom is a guide to how far off course you might be. If the MMSI you receive has an associated name in your Directory, that name is automatically displayed.

The COMPASS screen (3) dynamically shows your heading and bearing. It is easily read rapidly as a convenience.

The DIGITAL screen (4) displays basic data regarding your vessel’s movement, direction, ETE, and distance.

You can display a fifth screen (5) that is similar to screen 4 starting from the RADIO screen. Press and hold the PUSH/SELECT control for approximately 2 seconds. The screen to the right appears. To return to the RADIO screen, press and release the PUSH/SELECT control.

Basic Operation

Turning the Radio On and Off

Press PWR to turn on the radio. The radio sounds a tone and a screen showing the user MMSI appears if previously set.

If you have not set a user MMSI, see “Setting Up a User MMSI” on Page 34.

Note:If the radio is turned on for at least 3 seconds after you select a channel, it remembers the last channel you tuned when you turn it off.

Press PWR again to turn off the radio.

Selecting a Channel

Rotate PUSH/SELECT to select a channel. Rotating PUSH/SELECT clockwise tunes forward through the channels, while rotating PUSH/SELECT counterclockwise tunes backward through the channels. The currently-tuned channel appears on the display.

If the radio is set to marine mode, channel numbers appear as two digits. If the radio is set to WX mode, channel numbers appear as one digit.

Note: If A appears next to a channel number, this indicates the channel is in a simplex mode on the ship station transmit side of an international duplex channel.

Transmitting and Receiving

To transmit, hold down PTT on the microphone. TX appears on the display. Release PTT to receive. TX disappears.

Notes:

•If the channel is set to transmit at low power, you can change it to transmit at high power by pressing HI/LO/SCRAMBLER. If you are attempting to transmit on a normally power restricted channel while transmitting, press HI/LO/SCRAMBLER while holding down the PTT switch to overide the restriction. No other key except HI/LO/SCRAMBLER works.

•If you transmit continuously for longer than 5 minutes, TX and the channel number blink and the radio stops transmitting. This warns you that PTT might be stuck. To resume transmitting, release PTT then press it again.

•The radio cannot transmit on Channel 15 (USA).

•If you hold down PTT while turning on the radio, the radio sounds an error tone and TX and the channel number blink. No key except HI/LO/SCRAMBLER works.

•You cannot transmit while the radio is set to WX mode or Scan mode. If you press PTT while the radio is set to Scan mode, the radio cancels that mode but does not transmit.

•The radio cannot transmit voice data on Channel 70. Only DSC data such as a Distress Call can be transmitted on Channel 70.
