User manual KENWOOD TM-V71E

[. . . ] A maximum of 280 memory channels are available, 140 each for VHF and UHF. “Visual Scan” graphically and simultaneously shows the conditions of up to 147 frequency channels. The Dual Band RX feature allows two frequencies to be simultaneously received. A large, dot matrix LCD with alpha-numeric display capability is positive and negative reversible. [. . . ] After becoming comfortable with how to use all types of Scan, the monitoring flexibility gained will increase your operating efficiency. This transceiver provides the following conventional scans in addition to “Visual Scan” {page 41} that may be new to you. When using with CTCSS and/or DTSS: • • While using CTCSS, Scan stops and the squelch opens only when received signals contain the matching CTCSS tone. However, if the signals do not contain the matching DTSS code, the squelch does not open. When both CTCSS and DTSS are ON, Scan stops for signals that contain the matching CTCSS tone. However, if the signals do not contain the matching DTSS code, the squelch does not open. • Scan Type VFO Scan Memory Scan Program Scan MHz Scan Call/VFO Scan Call/Memory Scan Scan Range All frequencies tunable on the band Frequencies stored in the memory channels All frequencies in the range selected on the band All frequencies within 1 MHz range Call channel plus the current VFO frequency Call channel plus the memory channel last used Note: x Remember to adjust the squelch threshold level before using Scan. x 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. 40 VISUAL SCAN While you are on the air, Visual Scan allows you to monitor frequencies near the current operating frequency. Visual Scan graphically and simultaneously shows how all frequencies in the selected range are busy. You will see up to 14 segments, for each channel, that represent 7 S-meter levels (2 segments per level). You determine the scan range by selecting the center frequency and the number of channels. The default number of channels is 49. S-meter level 7 6 5 4 3 2 1 s Selecting the Number of Channels 1 Press [MNU] to enter Menu mode. Downward scan: Turn the Tuning control counterclockwise or press Mic [DWN]. 4 To quit VFO Scan, press [BAND SEL] for the band being scanned or [VFO]. • When scanning the TX band, you can also press Mic [PTT] to quit Scan. 4 To quit Memory Scan, press [BAND SEL] for the band being scanned or [MR]. • When scanning the TX band, you can also press Mic [PTT] to quit Scan. Note: The squelch must be closed for Scan to function. Note: x At least 2 or more memory channels must contain data and must not be locked out. While Scan is being interrupted, the channel number blinks. 44 s Locking Out Memory Channels Memory channels that you prefer not to monitor while scanning can be locked out. Lock out any memory channel with the following procedure: 1 Select the desired band. 3 Turn the Tuning control, or press Mic [UP]/[DWN] to select the desired memory channel. 4 (Memory). CALL PWR 8 Press [MNU] again to exit Menu mode. • "L" appears beside the memory channel number to indicate that the channel has been locked out. CALL PWR 1 2 3 2 VOL SQL 4 5 6 Lockout for an individual channel can be canceled by repeating the above procedure. Note: The L1 to L3 and U1 to U3 memory channels cannot be locked out. 7 8 9 10 VOL SQL 2 11 12 6 Press [s], then select item No. 1 (Lock Out). CALL PWR 13 14 15 VOL SQL 2 1 16 17 18 19 20 21 7 Press [SET] to toggle Lockout ON or OFF (default). 45 PROGRAM SCAN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Program Scan is similar to VFO Scan except that you select the frequency range of the scan. s Setting Scan Limits You can store up to three scan ranges on each band, using memory channels L1/U1, L2/U2, and L3/U3. 2 Turn the Tuning control, or press Mic [UP]/[DWN], to display the desired lower limit. 4 Turn the Tuning control, or press Mic [UP]/[DWN], to select channel L1, L2, or L3. 6 Turn the Tuning control, or press Mic [UP]/[DWN], to display the desired upper limit. 8 Turn the Tuning control, or press Mic [UP]/[DWN], to select channel U1, U2, or U3. • If you have selected for example L1 in step 4, select U1. 9 Press [MR]. • The upper limit is stored in the channel. 10 To confirm the stored scan limits, press [MR], then select the L and U channels. Note: x The lower limit must be lower in frequency than the upper limit. x The lower and upper limits must be selected on the same band. 5 Press [MR]. • The lower limit is stored in the channel. 46 s Using Program Scan 1 Select a frequency equal to or between the programmed scan limits. [. . . ] Nothing appears on the display. Probable Cause 1 The power cable was connected backwards. 2 One or more of the power cable fuses are open. Corrective Action 1 Connect the supplied DC power cable correctly: Red © ( + ); Black © ( – ). After inspecting and correcting any problems, install a new fuse(s) with the same ratings.
