Motorola’s DTR Series is the perfect partner for small business communications.

DTR Series – The Digital Difference

What makes the DTR Series perfect for your on-site operation? Digital technology. It enables coverage extended by 20% up to 45% longer operation on a single charge, and digital audio quality—which stays loud and clear everywhere you have coverage.

Each unit has its own unique 11-digit identification, bringing you new group calling options:


Public group call—all other DTR Series™ radios on the same group ID and channel hear communications, similar to analog radios.


Call and talk privately with a specific user. A private call recipient can receive an alert—either an audible or vibrating signal (DTR550 only). And the recipient’s unit displays the caller’s ID.

Individual unit identification also enables:
  • Call forwarding to other radio IDs—notify others that you’re unavailable and allow them to speak with another contact for assistance.
  • Transmit ID—receiving radios will display the radio ID of the transmitting unit and if listed in the receiving radio’s contact list, the transmitting unit’s radio name.
The DTR410™ and DTR550™ also feature:
  • Short message service (SMS) text messaging—with a total of ten preset messages for example, “I’ll call you back in 5 minutes,” and support for keyed-in custom messages – via an optional keyboard or SMS software loaded on your PC – to meet more specific needs.
  • Scroll list—you can view a recent-calls list, showing the source and target of the last 20 transmissions with time and date information

The DTR410™ digital on-site two-way radio presents a better way for small businesses to communicate. It also offers enhanced performance with wide coverage, longer battery life and clear, crisp audio. Digital one-to-many calling networks with other DTR radios on the same group ID and channel, for enhanced compatibility.

The DTR550™ digital on-site portable two-way radio operates at 900 MHz and offers enhanced communication options, including Digital One-to-One Calling and Digital One-to-Many Calling (Public Group and Private Group). It also provides enhanced performance with greater coverage, longer battery life and digital audio quality that is loud and clear everywhere you have coverage.
