SCAN Scan is a useful function for hands-off monitoring of your favorite frequencies. By becoming comfortable with how to use all types of Scan, the monitoring flexibility gained will increase your operating efficiency. The transceiver provides the following types of Scan: Scan Type Purpose Program Scan Monitors frequencies in the range that you select. All-channel Scan Monitors all RX frequencies that you store in the Conventional memory channels. Memory Scan Monitors all RX frequencies Group Scan stored in the Conventional memory channels of the desired group. PROGRAM SCAN Program Scan monitors the range between the start frequency and the end frequency that you store in Conventional memory channels 90 to 99. For a refresher on how to store Program Scan limits, refer to "STORING FREQUENCY RANGES" {page 43}. You can select a maximum of 10 memory channels and sequentially scan the ranges that you previously stored in those channels. Program Scan starts with the smallest channel number and repeats the sequence as shown below. 14.150 (Start freq.) Ch 93 14.300 (End freq.) 7.030 (End freq.) Ch 95 7.070 (Start freq.) 21.200 (Start freq.) Ch 97 21.350 (End freq.) 1 Press [A/B] to select VFO A or VFO B. 2 Press and hold down [SCAN], then using the numeric keys enter the second digit of each memory channel you desire to scan, i.e. 3 for Ch 93, 357 for Ch 93/Ch 95/Ch 97, etc. 3 Release [SCAN] to start Program Scan. • Releasing [SCAN] before entering channel numbers selects the channels that you selected last time for Program Scan. • To jump to the desired frequency while scanning, turn the Tuning control or MULTI/CH control, or press Mic [UP]/[DWN]. • When in a mode other than FM, turning the RIT/XIT control clockwise decreases the scan speed, and counterclockwise increases the speed. "P1" to "P9" on the display show the current speed (P1: maximum, P9: minimum). • When in FM mode, Scan automatically stops on a channel in which a signal is present. The transceiver remains on the same channel for either a short time (Time-operated mode) or until the signal drops (Carrier-operated mode), depending on which one you select via Menu No. 10. Refer to "MEMORY SCAN" for further information. 4 To stop Scan, press [SCAN] or [CLR]. Note: ◆ If you have turned the SQL control clockwise far beyond the squelch threshold when in FM mode, Scan may fail to stop at a channel in which a signal is present. If this happens, turn the SQL control slightly counterclockwise. ◆ If you press [SCAN] before storing any frequency range, then the lower and upper frequency limits of the transceiver are stored in memory channel 90, and Program Scan is activated using this channel. ◆ When the current receive frequency is within one of the ranges that you select by channel numbers, Scan starts with the current frequency. The operating mode stored in the channel with that range is used. ◆ When the current receive frequency is outside all the ranges that you select by channel numbers, Scan starts with the start frequency stored in the smallest channel number. ◆ Operating mode can be changed during scanning, but the memory channel is overwritten with the changed mode. ◆ When the current Scan range is smaller than a single step of the MULTI/CH control, turning this control clockwise causes Scan to jump to the start frequency, and counterclockwise to the end frequency. ◆ Starting Program Scan switches OFF the RIT and XIT functions. ◆ When in FM mode, Program Scan monitors rounded off frequencies regardless of the Menu No. 05 selection. SCAN HOLD This function stops Program Scan for approximately five seconds and then resumes Scan when you jump to the desired frequency by turning the Tuning control or MULTI/CH control, or pressing Mic [UP]/[DWN]. To use this function, access Menu No. 09, and select ON. The default is OFF. 46
