52 FT-817 Operating ManualThis transceiver contains a wide variety of scanning capabilities. Whether you are in theVFO mode or one of the memory modes, scanning operation is fundamentally identical inall configurations, but with the following differences: In the VFO mode, scanning causes the transceiver to sweep up or down the band,pausing or halting on any signal encountered; In the Memory mode, the scanner will scan the programmed memories, and can beinstructed to skip certain memories during scanning; In the Programmable Memory Scan (PMS) mode, the scanner will scan the bandwithin user-programmed frequency limits.Scanning Operation1. Set the knob to the point where background noise is silenced. A typical setting,for effective scanning operation, will be at 12 o’clock or slightly clockwise from thisposition.2. Set the transceiver into the operating configuration in which you wish to scan (VFO orMemory; PMS will be described later).8. Press the key momentarily, then rotate the knob, as needed, until OperatingFunction Row [SCN, PRI, DW].3. Press the (SCN) key momentarily to start upward scan (toward higher frequenciesor higher memory channel numbers).4. Rotate the knob or knob counterclockwise to toggle the scanning directiondownward.5. The scanner will now cause the transceiver to increment in the chosen direction until asignal is detected. When a signal is encountered which opens the Squelch, In the FM/AM modes, the scanner will pause until the signal disappears (at the end of the otherstation’s transmission), at which point scanning will resume. While the transceiver is inthe “Pause” condition, the decimal points in the frequency display area will blink. See“Scan-Resume Choices” on the next page for details of how to customize the resumptionof scanning, In the SSB/CW modes, the scanner will slow down (but doesn’t stop).6. Press the PTT switch on the microphone to cancel scanning.You may also press and hold in either the [UP] or [DWN] key on the microphonefor 1/2 second to initiate upward or downward scanning, respectively, if Menu #37(MIC SCAN) is set to “ON.”SCANNING O PERATION
