SCANS 8 ■ Preparation For a Programmed scan: Program scan edge frequencies into Program Scan Edge channels "P1" and "P2," in the same manner as programming Memory channels (p. 70) For a Memory scan: Program two or more Memory channels. (Program Scan Edge channels will not be scanned.) (p. 70) For a Select Memory scan: Set two or more Memory channels as Select Memory channels. (p. 80) For a ∂F scan: Set the ∂F span (∂F scan range) in the "SCAN" screen. (p. 81) • Scan Resume function You can select the scan to resume or cancel, after detecting a signal, in the Scan Set mode. The Scan Resume function must be set before starting a scan. (p. 77) • Scan speed The scan speed can be set to high or low, in the Scan Set mode. (p. 77) • 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 opens. The scan resumes, or is cancelled, depending on the "Scan Resume" setting. (p. 77) When the tuning step is 5 kHz or more: If Scan Resume is ON, the scan pauses when a signal is detected, then resumes. If the Scan Resume is OFF, the scan does not resume. For a 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. (p. 77) ■ 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. 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. • The VSC function is available for phone modes (SSB, AM and FM). • The VSC function resumes the scan on unmodulated signals, regardless of whether the Scan Resume function is set to ON or OFF.
