16、 VFO, PM) DUAL RECEIVE ON SAME BAND (VxV, UxU) In addition to simultaneous receive on VHF and UHF bands, the TM-V708A can receive two frequencies on the very same band. This means, for example, that you can have both the call channel and local channel, or the repeater channel and local channel, on t

17、he same band. “FIVE-IN-ONE” PROGRAMMABLE MEMORY To suit different situations, the TM-V708A has a programmable memory that can store five entire operating profiles, ready for instant recall at the push of a button. Each profile includes such settings as positive/negative display mode, dimmer level, f

18、requency range, and memory mode. 200 MULTIFUNCTION MEMORY CHANNELS Enjoy capacity as well as versatility: there are 200 split memory channels for storing essential data transmit and receive frequencies, frequency step, tone frequency, etc. And for greater convenience, you can opt to identify each ch

19、annel with up to 8 alphanumeric characters (Memory Name function). MULTIPLE SCAN In addition to VFO scan, program scan, MHz scan, memory scan and call scan, the TM-V708A has a memory bank scan that allows you to select which of the 10 memory banks to scan. Another attractive feature is visual scan:

20、by automatically checking above and below the frequency currently in use, and graphing the results on the LCD, this is handy for searching out open channels. Also featured are scan resume (time-operated, carrier- operated, and seek), memory channel lockout, tone scan, CTCSS scan, and DCS scan. 104-CODE DIGITAL CODE SQUELCH In addition to CTCSS (38 EIA Standard subtone frequencies) and 1750MHz tone burst, the TM-V708A is equipped for DCS (Digital Code Squelch, 104 codes). Pick a DCS code and you can be sure that the squelch will only open for reception when the other party uses the same code.
