44 FT-1900R OPERATING MANUALBASIC S CANNER O PERATIONBefore activating the scanner, make sure that the Squelch is set to silence the backgroundnoise when no signal is present. Scanning is not possible while the Squelch is open (if noiseor signals are being heard).Scanning may be started or stopped using the microphone’s [UP] or [DWN] button. Thefollowing techniques are used for scanning: Pressing and holding in either the [UP] or [DWN] button for one second in the VFOmode will cause upward or downward band scanning, respectively, to begin. Pressing and holding in either the [UP] or [DWN] button for one second in the Memorymode will cause memory channel scanning toward a higher- or lower-numbered memorychannel, respectively. Scanning pauses when a signal opens the squelch, and the decimal point on the displaywill blink. You can choose one of three scan-resume modes (described later). To halt the scan manually, the easiest way is to push the PTT switch on the microphonemomentarily (no transmission will occur while you are scanning). The scan may also behalted manually by pressing the microphone’s [UP] or [DWN] button, or the [D/MR(MW)] key.In the factory default setting, the scanner sweeps all frequencies while the VFOmode and all memory channels while the Memory mode. You may change thesweep range of the VFO mode to ±1 MHz, ±2 MHz, or ±5 MHz, or sweep only thoseMemory Channels with the same “first” or “first” and “second” digits of the alpha/numeric tag as the first channel on which scanning started, using Set Mode items “28MEM.SCN” and “56 VFO.SCN.” See pages 77 and 82 for details.S CANNING
