TM-V7A/E in detail: Dual-mode reversible LCD A world first: the cool-blue LCD panel -- capable of displaying dot-matrix characters -- can be switched between positive and negative display modes to ensure optimum visibility in all conditions. The control panel is large (51.5 x 105 mm) and features four multifunction keys -- with key function display -- for improved operating ease. "Four-in-one" programmable memory The TM-V7A/E has a multiple "personality" to suit different conditions. Its programmable memory can store four 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, frequency range, and memory mode. Dual receive on same band (f2) In addition to simultaneous receive on VHF and UHF bands, the TM-V7A/E can receive two frequencies on the same band. Monoband use is also possible. Up to 280 multi-function memory channels There's capacity as well as versatility: up to 280 memory channels for storing important data -- transmit and receive frequencies (independently), frequency step, tone frequency, etc. (180 channels when using Memory Name function.) Memory Name function For greater convenience, you can choose to identify each channel with up to 7 alphanumeric characters. In this mode, the number of memory channels available is 180. Visual scan with pause By automatically checking above and below the frequency currently in use, and graphing the results on the LCD (147 channels max.), this new feature is convenient for searching out open channels. Multi-scan functions Full band and programme band scans, memory scan with memory channel lock-out, MHz scan and call scan are all available. For each band there are TO (time-operated) and CO (carrier-operated) scan stop modes. DTSS selective calling with page function Built-in DTSS (Dual-Tone Squelch System) allows DTMF access: the squelch is opened only when a specific 3-digit code has been received. The page function alerts you to incoming calls and opens the squelch if the receiver has been programmed to accept a DTMF tone group. And even during normal reception (squelch open), the TM-V7A/E can be on the alert for a predetermined code. Built-in CTCSS encoder/decoder The CTCSS (Continuous Tone Coded Squelch System) encoder/decoder enables operation of the 38 EIA-standard CTCSS subtone frequencies. Auto simplex checker ASC will automatically check whether it is possible to switch from a repeater to simplex communications. Advanced Intercept Point You can choose either high sensitivity for simplex/weak-signal work, or a high intercept point -- using Kenwood's own AIP circuitry -- to minimize intermod or adjacent channel interference. 6-pin mini DIN connector for 1200/9600 bps packet The front panel features a connector for hooking up to a TNC, enabling either standard 1200 bps or 9600 bps high-speed packet communications. Quick-release detachable front panel kit (option) To enhance security, simply remove the compact front panel whenever the car is left unattended. If the optional quick-release kit is used, the panel can be mounted virtually anywhere since the microphone cable connects directly to the main unit. Guide function There's no need to carry the manual with you -- the friendly guide function displays simply operating instructions at the touch of a button.
