Using the Scrambler The radio's optional scrambler makes voice transmissions unintelligible to other radios without a scrambler or that are not set to the same scrambler code, and 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 39) to use the scrambler. Note: You cannot use a WHAM wireless microphone to use the scrambler. Hold down HI/LO/SCRAMBLER for 2 seconds to turn on the scrambler. SCRM appears on the display. To turn off the scrambler, hold down HI/LO/SCRAMBLER for 2 seconds. SCRM 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. Rotate PUSH/SELECT to select another weather channel. To stop listening to the weather broadcast, press WX/ ALERT again. 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. ALT appears. If the radio receives a weather alert, it sounds a tone and ALT blinks. You can turn off the tone by pressing any key. To turn off weather alert, hold down WX/ALERT for 2 seconds. ALT disappears. 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 34 for more information). If the radio finds a match, it sounds a tone and ALT flashes. Press any key to turn off the tone 24 Basic Operation
