Motorola DM4000

Versatile and powerful, MOTOTRBO combines the best of two-way radio functionality with the latest digital technology. DM4000 Series radios integrate voice and data seamlessly, offer enhanced features that are easy to use, and deliver operations-critical advantages like integrated Bluetooth® and Intelligent Audio.


When it comes to exceptional audio clarity, the quality of digital can’t be denied. With the DM4000 Series mobiles, you get digital quality plus unique features to help your employees hear and speak clearly, wherever they work. With Intelligent Audio, the radio volume automatically adjusts to compensate for background noise so workers don’t have to adjust their radio volume to avoid missing a call in loud situations or disturbing others when they move into quiet places. Increased background noise suppression filters out unwanted external clamour – from road traffic to the roar of engines. Bluetooth® audio, built in to the radio, provides voice communication with exceptional clarity – giving your people the freedom to move without wires. Also, IMPRES™ audio accessories enhance noise suppression and improve voice intelligibility for smarter audio than they’ve ever experienced before


DM4000 Series radios are available with integrated GPS that enables location tracking of mobile work teams and text messaging between radios enables communication when voice isn’t feasible. The large, full-colour display operates in day or night mode, for easy viewing of contact lists, text messages and work order tickets even in bright sunlight. Models are also available that feature integrated Bluetooth enabling the radio to wirelessly interface with Bluetooth-enabled devices such as barcode scanners and magnetic card readers to facilitate the collection of critical information in the field.


Because MOTOTRBO uses TDMA digital technology, you get integrated voice and data, twice the calling capacity and clearer voice communications. Also, the smart IMPRES™ technology in our high-powered accessories enables easier communications – everywhere your people travel.


DM4000 Series radios offer plenty of features your business seeks – including enhanced call signalling, basic and enhanced privacy-scrambling, option board expandability, the Motorola-unique transmit interrupt suite to prioritise critical communication the moment you need it and compatibility with SCADA solutions for utility and public service monitoring and alarms. Programmable button features appear on the display for easy viewing and quick access. And when workers can’t be distracted, customisable voice announcement provides audible confirmation of channel and zone changes as well as programmable button features, eliminating the need to view the display.


Your work crews are on the go – picking up loads, dropping off cargo, repairing roads or restoring power after a storm. That’s why you need the far-reaching performance of MOTOTRBO. IP Site Connect helps to dramatically improve customer service and productivity by using the Internet to extend coverage to create a wide area network, enhance single site coverage or link geographically dispersed locations. Capacity Plus provides single-site trunking expanding capacity to over 1,000 users. Combining the benefits of both solutions, Linked Capacity Plus is an entry-level, multi-site trunking solution that expands capacity and extends coverage so large work teams can stay connected across a wide area. So whether you want expanded coverage at a single site or across multiple ones, MOTOTRBO can be scaled to your needs.


Keeping operations running smoothly during a change in communication systems is vital to business. It’s easy to migrate to digital with DM4000 Series radios because they operate in analogue and digital mode while the dynamic mixed mode repeater functionality streamlines automatic switching between analogue and digital calls. So you can begin using MOTOTRBO radios and repeaters on your existing analogue system, and when your time and budget allow, move to digital at your own pace.


DM4000 Series mobile radios undergo Motorola’s unique Accelerated Life Testing to help ensure they will stand up to the hard knocks of everyday use. For even greater peace of mind, they are backed by a two-year Standard Warranty.
