UM425 VHF DSC Marine Radio UM425 VHF OM.indd 1 28/9/11 11:55:11 AM Making a distress call NOTE: There is no official VHF DSC shore infrastructure in Australia. Vessels fitting VHF DSC equipment should realise that this equipment can only be used for vessel - to - vessel alerting in the Australian region. There is no official shore-based infrastructure but there are a number of volunteer marine rescue (VMR) stations that have installed VHF DSC and a check with your local VMR should be made. Making a DSC DISTRESS Call Lift the red cover. Press and hold the DISTRESS button for three seconds. The UM425 transmits your boat’s location every few minutes until you receive a response. NOTE: If the radio displays ENTER USER MMSI, cancel the automatic distress call and make a normal voice distress call. Making a voice distress call Lift the red cover and press the DISTRESS button. Speak slowly -- clearly -- calmly. For future reference, write your boat’s name & call sign here: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. Make sure your radio is on. On the microphone, press the 16/9-TRI button to switch to Channel 16 (156.8 MHz). (If the corner of the display does not show 16, press the 16/9-TRI button again until it does.) Press the PUSH TO TALK button on the microphone and say: "MAYDAY --MAYDAY-- MAYDAY." Say "THIS IS {name or call sign of your boat}." Say "MAYDAY {name or call sign of your boat}." Tell where you are: (what navigational aids or landmarks are near, or read the latitude and longitude from your GPS). State the nature of your distress, e.g. are you sinking, medical emergency, man overboard, on fire, adrift, etc. Give number of persons aboard and conditions of any injured persons. Estimate present seaworthiness of your ship, e.g. how immediate is the danger due to flooding or fire or proximity to shore. Briefly describe your ship (length, type, color, hull). Say: "I WILL BE LISTENING ON CHANNEL 16." End message by saying "THIS IS {name or call sign of your boat}, OVER." Release the PUSH TO TALK button and listen. If you do not get an answer after 30 seconds, repeat your call, beginning at step 3, above. 2 UM425 VHF OM.indd 2 28/9/11 11:55:11 AM Making a distress call 3 UM425 VHF OM.indd 3 28/9/11 11:55:11 AM

As it powers on, the radio displays the user MMSI number; if there is no MMSI set, the radio displays MMSI not entered. When it powers on, the radio selects the last channel used. Setting the UIC channel mode (USA/CAN/INT) NOTE: This menu selection is hidden by default. To access this feature; Turn on the radio while holding down SCAN and ▲buttons. The feature will be hidden again from the menu when power is turned off. The radio comes preset to use the UIC channels assigned for International waters. If you are operating in an area that uses Canadian or United States UIC channels, you will need to change the channel mode. 1. 2. 3. 4. Press the MENU-PA button to display the menu, and choose the Setup sub-menu. Select USA/CAN/INT. The screen displays the UIC channel setup. Highlight the channel mode you want to use: US (USA mode), Canadian (Canada mode), or international (Intl mode). Press the SELECT button. The radio activates the new channel mode and exits the menu. How It Works The UM425 has two basic modes of operation: Operation mode What it does: Use it when: To turn it on/off: Normal mode Monitors a single marine radio channel and lets you talk on that channel. You want to talk to another station on a specific channel. (default mode) Scan mode Monitors all the channels you save into memory. You have a small group of channels you use most often and want to check them for traffic. Press the SCANMEM button. 12 UM425 VHF OM.indd 12 28/9/11 11:55:15 AM How It Works In addition to the two main operation modes, the UM425 also provides two different “watch” modes which you can activate during any of the two basic modes. In the watch modes, the radio briefly checks for activity on a specific channel, then returns to its previous mode. Watch mode What it does: Use it when: To turn it on/off: Triple Watch Checks for activity on channels 16 and 9 every two seconds. You want to monitor a channel yet maintain a watch on channels 16 and 9. Press and hold the 16/9-TRI button for two seconds. Dual Watch Checks for activity You want to monitor on channel 16 every a channel yet two seconds. maintain a watch on channel 16. Change Triple Watch to Dual Watch in the setup menu, then press and hold the 16/9TRI button for two seconds. NOTE: You are required to monitor channel 16 whenever your boat is underway. You should have either Triple Watch or Dual Watch on at all times. Normal mode operation Normal mode monitors whatever channel you select, and you can transmit on that channel also. While using normal mode, the display lets you see the following information (not all indicators will display at the same time): Channel mode (USA, CANadian, or INTernational) Transmit power (1 W or 25 W) Current channel is stored in memory Status messages (see the status message table) 25 25 Watts INT Memory GPS Data OK Marine Operator Current channel number Current channel name (if the name is too long, the name line scrolls) 13 UM425 VHF OM.indd 13 28/9/11 11:55:15 AM How It Works Table 5 - Normal mode status messages Message Meaning GPS Data OK The radio is receiving valid GPS data.

Making a voice MAYDAY call (see inside front cover) Setting the volume Turn the volume knob clockwise to increase the speaker volume; turn it counter-clockwise to decrease the volume. Setting the squelch level The squelch feature reduces the level of static on the speaker by filtering out the background channel noise. At the lowest squelch level, the speaker plays all radio signals, including any noise on the channel. Setting the squelch level higher filters out channel noise and lets only actual radio transmissions through. Strong signals Weak signals Noise No Squelch Medium Squelch High Squelch 19 UM425 VHF OM.indd 19 28/9/11 11:55:16 AM Using Your Radio While listening to a channel, adjust the SQUELCH knob until the noise is filtered out and you can only hear the transmission. If you switch to a channel with a lot of noise or with a weak transmission, you may need to adjust the squelch level again. NOTE: Setting the squelch level too high may prevent you from hearing weaker transmissions. If you are having difficulty hearing a transmission, try setting the squelch level lower. Changing the channel Press the CHANNEL UP or CHANNEL DOWN buttons briefly to scroll through the channels one channel at a time. Press and hold the channel up or down button to quickly scroll through the channels. Making a transmission To make a transmission, press and hold the microphone PUSH TO TALK button. Release the PUSH TO TALK button when you're finished talking to let the other party respond. • To prevent stuck microphone problems or situations where the PUSH TO TALK button is pushed accidentally, the radio limits your talk time to 5 minutes in a single transmission. If you talk for over 5 minutes continuously, the display shows RELEASE MIC BUTTON. • For the best sound quality, hold the microphone about two inches away from your mouth. • You cannot transmit while the radio is in scan mode. • See the channel list on page 57 for a list of receive-only channels. Boosting the transmission power In most situations, the 1 Watt transmission power is all you need. If you find yourself far away from other stations and have trouble getting a response, you may need to boost the transmission power from 1 Watt to 25 Watts: 1. Select the channel you want to transmit on. 2. Push the 1/25W button. The display shows 25 Watts in the upper left hand corner. 3. The transmit power remains at 25 Watts until you change the setting back. Push the 1/25W button. The display shows 1 Watt. NOTE: Don’t forget to change the transmission setting back to 1 Watt when you move closer to other stations. 20 UM425 VHF OM.indd 20 28/9/11 11:55:16 AM Using Your Radio NOTE: By default, when you change to channel 16, the radio automatically boosts the power to 25 Watts. Be sure to change the power back to 1 Watt if you are not making an emergency transmission. Some channels limit the power of transmission to 1 Watt so that there is less interference between boaters attempting to use the channel at the same time. If you switch to one of these channels, the radio changes back to 1 Watt automatically. See the channel list on page 57 for a list of power-restricted channels. Choosing Triple Watch or Dual Watch In Triple Watch mode, the radio briefly checks channels 16 and 9 every two seconds. In Dual Watch mode, the radio checks channel 16 only. Generally, Triple Watch is used in areas where channel 9 is used as a hailing frequency, while Dual Watch is used in areas where channel 16 is used for distress and hailing. Your radio comes set to use Triple Watch; if you want to use Dual Watch instead, you will have to select it in the setup: MENU Setup SELECT Dual/TriWatch Dual/TriWatch Dual Watch Triple Watch SELECT [Exit] 88 1.

Digital Selective Calling or DSC is a standard that allows you to call other stations using their unique identification code (the Maritime Mobile Service Identity or MMSI number), just like you would call a phone number. To call another station, just enter that station’s MMSI number and choose the voice channel you want to talk on. The radio uses channel 70 to transmit your MMSI number to the other station along with the voice channel you requested. 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 provides a system for automated distress calls. At the touch of a button, 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 acknowledgement. The DSC standard dedicates a VHF channel—channel 70—to digital transmissions only. Since digital transmissions require less bandwidth voice transmissions, channel 70 avoids the problems of busy voice channels. Advanced DSC features The UM425 supports the following DSC features: Feature Menu Item Function Individual Call Individual Contact another vessel from your directory. Group Call Group Contact all vessels that share your group MMSI code. All Ships Call All Ships Broadcast to all vessels within range (used for safety or advisory messages.) Position Request POS Request Request the current location of another vessel. Position Send Position Send Transmit your current location to another vessel. Test Call Test Make sure your radio is working and configured correctly Name and MMSI Directory Directory Store a list of 20 names and MMSI identification codes for DSC calls. Standby Mode Standby Automatically respond to all DSC calls with an “Unavailable” status.

However, it is a precision electronic instrument, so you should follow a few precautions: • If the antenna has been damaged, you should not transmit except in the case of an emergency. A defective antenna may cause damage to your radio. • You should arrange for periodic performance checks with your Uniden dealer. Common questions Problem Things to Try The radio won’t power on. Check the power connections. Check the fuse. Check the master battery switch and branch circuit that connect to the radio. The radio won’t transmit. Make sure you are not in scan mode. Make sure you are not trying to transmit on a receive-only channel (see the channels and frequency tables starting on page 57). Make sure you are transmitting at the correct power level for this channel (see the channels and frequency tables starting on page 57). Make sure the duration of each transmission is less than 5 minutes. Noise comes out of the speaker all the time Adjust the squelch level; it is probably too low. I can’t hear anything (no volume) from the speaker. Adjust the squelch level; it is probably too high. I can transmit, but no one can hear me. Check your UIC channel settings (see Setting the UIC channel mode (USA/CAN/INT) on page 12). I can’t read the display. Adjust the contrast and backlight brightness level (see page 22) The display is too bright at night. Adjust the backlight brightness level. (see page 22) I can’t see any words on the display. Reset the radio back to the default contrast level: turn off the radio; hold the menu key and turn it back on. 51 UM425 VHF OM.indd 51 28/9/11 11:55:22 AM Maintenance and Troubleshooting Problem Things to Try I’m not getting any GPS data on my display. Make sure your GPS receiver is correctly connected (see Connecting to a GPS receiver). Make sure your GPS receiver is working properly. Make sure that your GPS receiver supports the NMEA parameters described in NMEA Operation on page 63. I can’t make Group DSC calls. Make sure the Group MMSI was entered correctly. Where can I find my radio’s serial number? Look on the bottom side of the radio The radio won’t let me enter my User MMSI. What do I do? Contact customer service by visiting the customer support page on www.uniden.com.au or www.uniden.co.nz. 52 UM425 VHF OM.indd 52 28/9/11 11:55:22 AM Maintenance and Troubleshooting Engine Noise Suppression Interference from the noise generated by the electrical systems of engines is sometimes a problem with radios. The UM425 has been designed to be essentially impervious to ignition noise and alternator noise. However, in some installations it may be necessary to take measures to further reduce the effect of noise interference. The UM425 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 where you purchased the radio for more information. 53 UM425 VHF OM.indd 53 28/9/11 11:55:22 AM Specifications Specifications Table 9 - Radio specifications (All specifications are subject to change without notice.)

DSC: Frequently Asked Questions The following information is sourced from the Australian Maritime Safety Authority's DSC FAQ. What is the status of VHF DSC coverage in Australia? In Australian waters, VHF DSC is for ship-to-ship alerting. There is no official shore-based infrastructure but there are a number of volunteer marine rescue (VMR) stations that have installed VHF DSC and a check with your local VMR should be made. VHF DSC for small craft is primarily for distress, urgency and safety purposes. How should VHF DSC be used? In Australian waters, Channel 70 should be used for DSC distress alerts only. Once an alert has been sent the party in distress should monitor Channel 16, the distress and calling channel. Parties receiving the DSC distress alert should switch to Channel 16 and acknowledge the MAYDAY call by voice giving their identity and signalling “Received MAYDAY”. If the party in distress does not receive an acknowledgement to their DCS alert they should transmit the standard MAYDAY call by voice on Channel 16. There are still quite a number of boats that do not carry DSC radios. Because Channel 16 is the distress and calling frequency it should only be used for general traffic to raise another party. Once contact has been made, all routine traffic should be passed on another agreed VHF channel. Is a call sign or Maritime Mobile Service Identity (MMSI) needed? An MMSI is a unique nine-digit code set into your DSC terminal to identify your vessel. You need only one of these if you have multiple DSC radios. You use the same MMSI for all radios on board the one vessel as it is a ship’s identity. Because VHF radios now operate under a Class License there is no requirement for an official call sign but an operator must have a Maritime Radio Operators Certificate of Proficiency (MROCP). 64 UM425 VHF OM.indd 64 28/9/11 11:55:23 AM Regulations and Safety Warnings How can a MMSI be applied for? The Australian Maritime Safety Authority allocates MMSI. To apply for an MMSI complete the MMSI Application form available for download via www.amsa.gov.au/mmsi. This page has important information about MMSI and DSC radio. What qualifications are needed to operate a VHF DSC radio? The minimum qualification to operate a VHF radio with or without DSC is a Marine Radio Operator’s VHF Certificate of Proficiency (MROVCP). VHF radios are covered by a Class License so an individual station license is no longer required. The Marine Radio Operator’s Handbook produced by the Australian Maritime College provides further information about qualifications, licensing and DSC operations. It is available at www.amcom.amc.edu.au Antenna Selection and Installation Your UM425 has been designed to accommodate all of the popular marine VHF antennas. However, the selection and the proper installation of the antenna is the responsibility of the user or installer. The antenna used with this radio should be installed using the following guidelines to ensure a safe distance between the antenna and persons close by. • Small whip antennas (3 dB) or smaller should be installed with at least 1m away from any area where people are likely to be. • Larger antennas (6 dB or 9 dB) should be installed with at least 2m away. • While the radio is transmitting, do not come closer to the antenna than the recommended safe distance. • Do not touch the antenna when the radio is powered on and might begin transmitting. 65 UM425 VHF OM.indd 65 28/9/11 11:55:23 AM Two Year Limited Warranty UNIDEN UM425 VHF IMPORTANT Satisfactory evidence of the original purchase is required for warranty service Please refer to our Uniden website for any details or warranty durations offered in addition to those contained below.
