Mobile Radio Station Kenwood TK-D740E
VHF DMR Mobile Radio operates in DMR Digital and FM Analogue modes, even on the same channel.
Introducing the new TK-D740/D840 mobile radio stations with impressive DMR system line-up. Thanks to compliance with MIL-STD and IP54 environmental standards, they can be relied on through thick and thin.
As well as handling both analogue and digital communications, these user-friendly DMR radios can even operate in direct mode, without a repeater. They also offer KENWOOD Call Interrupt and also benefit in having KENWOOD enhanced audio quality. These truly resourceful team members will enable you to make the most of your legacy analogue equipment while also benefitting from digital communications.
Belonging to the DMR Tier II category, which covers licensed conventional systems, these radios are specified for 2-slot Time Division Multiple Access (TDMA) operation in 12.5 kHz channels. This means they can offer greater spectrum
Two in One - Digital & Analogue
These DMR radios can operate in both digital and FM analogue modes, switching automatically as needed. Interoperability with legacy analogue radios allows organizations to migrate to full digital at their own pace.
Dual-Slot Direct Mode
Up to two simultaneous direct-mode subscriber calls can be supported in a 12.5 kHz channel, without requiring a repeater, thus doubling channel capacity.
In an emergency or whenever a user needs to interrupt a call, Call Interrupt is available in both direct and repeater modes, while encoding or decoding. Also featured are emergency functions to help protect staff in remote areas, etc.
These TK-D740/D840 mobile radios conform to MIL-STD C/D/E/F/G standards for ruggedness, and are IP54 rated for water & dust intrusion, making them more than capable of withstanding harsh operating conditions. *Applies only when using a microphone KMC-35 or KMC-36.
2-Digit LED Channel Display with Brightness Control
The large 2-digit LED display provides a clear indication of which channel is being used, and the brightness level can be adjusted (high/low) to suit the time of day and ambient light conditions. The front panel also features 9 programmable function keys for enhanced operating ease.
Programmable Blue LED
The blue LED indicator can be customized to provide useful status information. For example, it can be used in combination with the orange LED for Selective Call differentiation.
Clear, Powerful Audio
A radio’s most important quality is clarity – being able to hear, loud and clear, what the other party is saying, and these mobiles deliver just that. For instance, the AMBE+2™ VOCODER technology accurately replicates natural human speech nuances for superior voice quality, even with high levels of ambient noise. Additionally, Voice Announcement can confirm the channel number, so there is no need to look at the display. English is the default language, but Spanish, French, German, Italian, Dutch and Russian are also available.
A series of programmed audio tones is used to specify one or more radios and initiate a conversation; all other radios will remain muted. Several signalling formats are available.
