SCANS 11 ■ Preparation For a Programmed scan: Program scan edge frequencies into Program Scan Edge channels "1A-3A" and "1b-3b." (p. 148) For a Memory scan: Program two or more Memory channels. (Program Scan Edge channels will not be scanned.) (p. 140) For a Mode Select scan: Program two or more Memory channels, all with the same operating mode. (p. 43) For a Select Memory scan: Program two or more Memory channels as Select Memory channels. (p. 151) For a ∂F scan: Set the ∂F span (∂F scan range) in the "SCAN" screen. (p. 152) • Scan Resume function You can select the scan to resume or cancel when detecting a signal in the Scan Set mode. The Scan Resume function must be set before operating a scan. (p. 147) • Scan speed The scan speed can be set to high or low in the Scan Set mode. (p. 147) • [MAIN DIAL] function How the [MAIN DIAL] functions during a scan, can be set in the Scan Set mode. (p. 147) • Squelch status ❍ The scan starts with the squelch open For a programmed scan: When the tuning step is 1 kHz or less: The scan continues until it is stopped manually- it does not pause*, even if signals are detected. * The scan is paused when the squelch is closed and then opened. The scan resumes, or is cancelled, depending on the Scan Resume setting. When the tuning step is 5 kHz or more: If Scan Resume is ON, the scan pauses on each step when a signal is detected, then resumes. If the Scan Resume is OFF, the scan does not start. For memory scan: If Scan Resume is ON, the scan pauses on each channel when a signal is detected, then resumes. If Scan Resume is OFF, the scan does not start. ❍ The scan starts with squelch closed The scan pauses when signals are detected. The scan resumes, or is cancelled, depending on the Scan Resume setting. ■ Voice Squelch Control function (Mode: SSB/AM/FM) This function is useful when you do not want unmodulated signals pausing or cancelling a scan. When the Voice Squelch Control (VSC) function is ON, the receiver checks received signals for voice components. The scan pauses, or is cancelled, if a received signal includes voice components, and the tone of the voice components changes within 1 second. See "Squelch status" as described above. The scan resumes if the received signal includes no voice components, or the tone of the voice components does not change within 1 second. q P ush [SSB] or [AM/FM] once or twice to select the operating mode. w P ush [MENU] to display the "M2" screen (Menu 2). e P ush [VSC](F-5) to turn the VSC function ON or OFF. • " " appears when the VSC function is ON. • Push [MENU] to return to the previous display.
