How It Works 12 Turning on the radio T urn the VOLUME-PWR knob clockwise to turn on the radio. 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.
13 How It Works NOTE: Y ou are required to monitor channel 16 whenever your boat is under- way . Y ou should have either T riple Watch or Dual W atch on at all times. In addition to the two main operation modes, the UM425 also provides two differ- ent “watch” modes which you can activate during any of the two basic modes.
How It Works 14 T able 5 - Normal mode status messages Message Meaning GPS Data OK The radio is receiving valid GPS data. Check GPS The radio is not receiving valid GPS data: check the GPS status screen and the GPS connection.

How It Works 16 Scan mode Y ou can save channels into memory and then use scan mode to monitor those channels. When the radio detects a signal on a channel, it pauses on that channel as long as the signal is received; when the transmission stops, the radio will continue scanning.
17 How It Works T o remove a channel from memory , set the radio to that channel, then • press and hold the SCAN-MEM button for two seconds. Memory will no longer show on the display . T o activate scan mode, press the • SCAN-MEM button. Press the SCAN- MEM button again to return to the previous mode.

Using Digital Selective Calling (DSC) Features 24 What is DSC? Digital Selective Calling or DSC is a standard that allows you to call other stations using their unique identication code (the Maritime Mobile Service Identity or MMSI number), just like you would call a phone number .
25 Using Digital Selective Calling (DSC) Features Getting an MMSI number In order to use DSC features, you must be assigned an MMSI number and program that number into your radio. There are two kinds of MMSI numbers: individual numbers for use by single boats and group numbers for use by eets, boating organizations, event coordinators, etc.
Using Digital Selective Calling (DSC) Features 26 3. Use the CHANNEL UP and CHANNEL DOWN buttons to change the rst of the nine digits; the CHANNEL UP button increases the number and the CHANNEL DOWN button decreases the number . 4. When the rst digit is correct, press the SELECT button.

Using Digital Selective Calling (DSC) Features 30 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.
31 Using Digital Selective Calling (DSC) Features When the other station accepts the call, both radios switch to the se- • lected response channel for voice transmission. If the other station cannot respond on the channel you selected, the • radio displays Not support CH .
Using Digital Selective Calling (DSC) Features 32 Making an automatic distress call If you have programmed your MMSI number , the UM425 can transmit an automated distress call with your current location and nature of the distress.
33 Using Digital Selective Calling (DSC) Features Receiving a DSC call If your radio receives an individual DSC call from another station, it sounds an incoming call tone and displays the name or MMSI number of the station calling you.

51 Maintenance and T roubleshooting Maintenance and T roubleshooting Due to its rugged design, the UM425 requires very little maintenance. Howev- er , it is a precision electronic instrument, so you should follow a few precau- tions: If the antenna has been damaged, you should not transmit except in • the case of an emergency .
Maintenance and T roubleshooting 52 Problem Things to T ry 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.
53 Maintenance and T roubleshooting 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.
