6 Press the Tuning control again to reset the PM channels. • Press [TONE] (BACK) to return to the previous display. • To exit without resetting the PM channels, press [F] (ESC). 41 SCAN Scan is a useful feature for hands-off monitoring of your favorite frequencies. Becoming comfortable with all types of Scan will increase your operating efficiency. This transceiver provides the following types of scans: Scan Type Scan Range Scans all frequencies on the current band. Scans all frequencies stored in the Memory channels. Scans the frequencies in the Memory channels which belong to the group you have specified. Scans all frequencies within the programmed range, on the current band. Scans all frequencies within a 1 MHz range from the originating frequency. Scans the Call channel as well as the currently selected VFO frequency or Memory channel. VFO Scan Memory Scan Group Scan Program Scan MHz Scan Call Scan Note: u Adjust the squelch level before using Scan. Selecting a squelch level too low could cause Scan to stop immediately. u While using CTCSS or DCS, Scan stops for any signal received; however, you will hear audio only when the signal contains the same CTCSS tone or DCS code that you selected. u When using S-meter Squelch, Scan stops when the received signal strength matches or exceeds the S-meter setting. Scan resumes 2 seconds after the signal level drops below the S-meter setting. u Pressing and holding [PTT] causes Scan to temporarily stop if it is functioning on a non TX band. u Starting Scan switches the Automatic Simplex Checker OFF. 42 SELECTING A SCAN RESUME METHOD The transceiver stops scanning at a frequency or Memory channel on which a signal is detected. It then continues scanning according to which resume mode you have selected. You can choose one of the following modes. The default is Time-operated mode. • Time-Operated mode The transceiver remains on a busy frequency or Memory channel for approximately 5 seconds, and then continues to scan even if the signal is still present. • Carrier-Operated mode The transceiver remains on a busy frequency or Memory channel until the signal drops out. There is a 2 second delay between signal drop-out and scan resumption. • Seek mode The transceiver remains on a busy frequency or Memory channel even after the signal drops out and does not automatically resume scanning. Note: To temporarily stop scanning and monitor weak signals, press the microphone PF key assigned to the Monitor function {page 66}. Press the PF key again to resume scanning. 1 Enter Menu mode and access Menu 514 (SC.RESM) {page 20}. 2 Set the Scan Resume mode to TO (Time-Operated), CO (Carrier-Operated) or SEEK. VFO SCAN VFO Scan monitors all frequencies tunable on the band, using the current frequency step size. 1 Select your desired band. 2 Press [VFO] (1s). • Scan starts at the current frequency. • The 1 MHz decimal blinks while scanning is in progress. • To reverse the scan direction, turn the Tuning control clockwise (upward scan) or counterclockwise (downward scan). You can also press microphone [UP]/ [DWN]. 3 To quit VFO Scan, press [VFO] again. 43 MEMORY SCAN Use Memory Scan to monitor all Memory channels programmed with frequency data. 1 Select your desired band. 2 Press [MR] (1s). • Scan starts at the current frequency. • The 1 MHz decimal blinks while scanning is in progress. • To reverse the scan direction, turn the Tuning control clockwise (upward scan) or counterclockwise (downward scan). You can also press microphone [UP]/ [DWN]. 3 To quit Memory Scan, press [MR] again. Note: u At least 2 Memory channels must contain data and must not be locked out of scan. u The L0/U0 to L9/U9 Memory channels will not be scanned. u You can also start Memory Scan when in Channel Display mode. While Scan is paused on a channel, the channel number blinks. n Locking Out a Memory Channel You can select Memory channels that you prefer not to monitor while scanning. 1 Press [MR], then rotate the Tuning control to select your desired channel. 2 Enter Menu mode and access Menu 202 (L.OUT) {page 20}. 3 Set the lockout to ON to lock the channel out of the scanning sequence. • To cancel lockout, set the lockout to OFF. • The icon appears on the display for a channel that has been locked out. Note: The L0/U0 to L9/U9 Memory channels cannot be locked out. 44 GROUP SCAN For the purpose of Group Scan, the 1000 Memory channels are divided into 10 groups, with each group containing 100 channels. Group Scan monitors only the 100 channels which belong to the specific group you are scanning. The channels are grouped as follows: 5 500 ~ 599 6 600 ~ 699 7 700 ~ 799 8 800 ~ 899 9 900 ~ 999 Memory Group Channel Range Memory Group Channel Range 0 0 ~ 99 1 100 ~ 199 2 200 ~ 299 3 300 ~ 399 4 400 ~ 499 1 Press [MR], then rotate the Tuning control to select a channel in your desired group. 2 Press the Tuning control (1s). • Scan starts at the current channel. • The 1 MHz decimal blinks while scanning is in progress. •...
