Benefits
Enhanced coverage, battery life, and audio quality aren't the only advantages of Motorola's new Digital On-Site Two-Way Radios. No license is required to operate Motorola 900 MHz units. And for enhanced security, Motorola added Frequency Hopping Spread Spectrum (FHSS) with 100 non-overlapping groups. Unlike analog radios, multiple group communications can occur simultaneously on the same channel with Motorola Digital On-Site Two-Way Radios.
In addition to these overall benefits, Motorola Digital On-Site Two-Way Radios allow you to take advantage of many leading-edge operational features that were never available previously.
Because the digital technology of the Motorola DTR550™ portable enables each unit to have its own unique 11-digit identification, you get a new level of radio communication versatility with these calling options:
Digital One-to-Many Calling
Public Group Call
All other Motorola DTR Series™ radios on the same group ID and channel hear communications, similar to an analog radio operation.

Transmit ID
Receiving DTR Series™ radios display the radio ID of the transmitting unit and, if listed in the receiving radio's contact list, the transmitting unit's radio name.
Scroll List
Can display frequently used group and private IDs for easiest access on your Motorola DTR Series™ radio. You can view a recent-calls list, showing the source and target of the last 20 transmissions with the time and date information.
Exceptional Durability
Rest assured that the Motorola DTR410 Digital On-Site Two-Way Radio will hold up under demanding conditions. U.S. Military 810 C, D, E, and F Standards are used in the design process to simulate the very harshest environments, including:
- Blowing rain
- Salt fog
- Blowing dust
- Vibration
- Shock
- Temperature storage
