[. . . ] Marine Radio OWNER'S MANUAL UM-525 Maritime Radio Services Operation Maritime transmitter Warning!ThisRade Opwill operate on channels/frequencies that have restricted use in the United States. The channel assignments include frequencies assigned for exclusive use of the U. S. Operation on these frequencies without proper authorization is strictly forbidden. [. . . ] The radio descrambles incoming scrambled voice transmissions if the transmitting radio is set to the same scrambler code. If the scrambler is turned on, the radio can communicate only with other radios set to the same scrambler code. You must install an optional scrambler board in the radio and set a scrambler code (see "Setting a Scrambler Code" on Page 43) to use the scrambler. SCRAM disappears. Using the Weather Function The FCC (Federal Communications Commission) has allocated channels for use by the National Oceanic and Atmospheric Administration (NOAA). Regulatory agencies in other countries have also allocated channels for use by their weather reporting authorities. NOAA and your local weather reporting authority broadcast your local forecast and regional weather information on one or more of these channels. To hear your local forecast and regional weather information, press WX/ALERT. Your radio scans through the weather band then stops on the first active weather frequency, and WX appears on the display. The radio returns to the last channel you tuned before you selected the weather channel. Using Weather Alert To set the radio so it alerts you if it receives a weather alert, hold down WX/ALERT for 2 seconds. Note: You cannot listen to weather broadcasts while the weather alert mode is active. Basic Operation 23 Using SAME Alert The National Weather Service precedes each weather alert with a digitally encoded SAME (Specific Area Message Encoding) signal, then a 1050 Hz tone. The SAME signal includes a FIPS (Federal Information Processing Standard) area code, and an event code that corresponds with the type of alert being sent. You can configure your radio to operate in SAME Standby mode, where it monitors a selected weather radio station for SAME alerts for areas you specify. You can program your radio with up to 30 FIPS codes for the areas you desire. The National Weather Service maintains a current list of FIPS codes at http://www. nws. noaa. gov/nwr/. If the radio receives a SAME alert tone, it checks the tone against any FIPS codes you stored (see "Setting FIPS Codes" on Page 38 for more information). Press any key to turn off the tone Performing a Radio Self Test Selecting this menu item performs a complete self test on the radio. · · · Hail Speaker Condition (Connect or Not Connected) GPS Condition (OK, Not Connected, No Data Flow, Sentences Not Supported) Battery Condition (OK, Voltage Too Low, Voltage Too High) To run the self test, select SELF TEST then press PUSH/SELECT. For more information about items that did not pass the test, rotate PUSH/SELECT to select the item, then press PUSH/SELECT to select it. DSC Operation Sending a DSC Distress Call Important: Never test your radio's distress feature under any circumstances. It is unlawful to send a false distress signal even for testing purposes. Your radio's distress feature lets you send a distress call using maximum (HI) power. If you momentarily press DISTRESS, the channel you were on at the time immediately changes to 16 and your power level changes to HI. At the end of 5 seconds, a condition screen appears listing several distress condition choices. [. . . ] When these sentences are received, the radio displays latitude/longitude, date, time, course, and speed. If any sentence except an RMC or GLL sentence is received, the radio uses the information based on the following priority order. Status:RMC > GLL > GNS > GGA Latitude/Longitude:RMC > GLL > GNS > GGA UTC Time :RMC > GLL > GNS > GGA > ZDA Date:RMC > ZDA Speed / Course:RMC Notes: · · If the radio received only a GLL sentence, the radio does not display the current speed, course, and date. If the radio received RMC and GLL sentences, the radio uses only the RMC sentence. Status data is used to check which GPS data is valid or invalid. NMEA Output When the radio receives a DSC Call (Distress, Position Reply, Position Send), it outputs a DSC/DSE sentence from the NMEA output port. [. . . ]
