Yaesu FTA-310 Operating Manual

FTA-310 OperATing MAnuAl32scannIng operatIonThe FTA-310 allows you to scan automatically in theVFO1 , Main Memory, “Book” Memory, or WeatherChannel2 modes. It pauses on signals encountered, soyou can talk to the station(s) on that frequency, if you like.1: In the VFO mode, the automatic scanner is onlyavailable in the COM band (118.000 ~ 136.975MHz); when the scanner reaches the uppermostfrequency in the COM band, it will revert to the bot-tom end of the COM band and repeat the scanningprocess until you cancel the scanning process.2: USA version only.If you wish to scan in the NAV band (108.000 ~ 117.975MHz), you can do so manually, as described at the right.Scanning operation is basically the same in each of theabove modes. Press and hold in the[SCAN (DW)] key for2 seconds to start theautomatic scanner up-ward (toward a higherfrequency or a higherchannel number). When the scanner encounters a signal, scanningpauses and the radio remains on that channel untilone second after the signal disappears, after whichscanning will resume. While the scanner remains paused on a frequency,the decimal point of the frequency display blinks.The display will be illuminated unless the ScanLamp Feature is turned off. To change the scan di-rection, turn the DIALselector knob one clickin the opposite direction. To stop the automaticscanner, press the PTTswitch or press down-ward on the VOLUME knob momentarily. You mayalso just press the [SCAN (DW)] key.The FTA-310’s automatic scanner is not operational in theNAV band (108.000 ~ 117.975 MHz), because the NAVstations (ILS, etc.) transmit constantly (thereby causingthe scanner to stop repeatedly). However, you can scanmanually in the NAV band, per the following procedure: Press and hold the [SCAN (DW)] key to start themanual scanner. Scanning will continue as long asthe key is depressed. Release the [SCAN (DW)] key to stop the manualscanner immediately.
