Features:
Enhanced coverage, battery life, and audio quality aren't the only advantages of our new digital on-site two-way radios. No license is required to operate our 900 MHz units. And for enhanced security, we added Frequency Hopping Spread Spectrum (FHSS) with 50 non-overlapping groups. Unlike analog radios, multiple group communications can occur simultaneously on the same channel.
In addition to these overall benefits, you’ll be able to take advantage of many leading-edge operational features that were never available previously.
Because the digital technology of the DTR650 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-One Calling
Call and talk privately with a specific user's radio. A private call recipient can receive an alert either an audible or vibrating signal. And the recipient's unit displays the caller's ID.

Digital One-to-Many Calling
Public Group Call. All other DTR Series radios on the same group ID and channel hear communications, similar to an analog radio operation.

Private Group Call. Program your DTR Series radios to communicate with specific sets of group members. Caller ID displays group identification.

Call Forwarding to Other Radio IDs. Notify others that you're unavailable and allow them to speak to another contact for assistance.
Transmit ID. Receiving 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.
Short Message Service (SMS) Text Messaging. For added convenience, the DTR550 is capable of sending and receiving 15 preset messages and also allows for keyed-in custom messages to meet more specific needs.
Scroll List. Can display frequently used group and private IDs for easiest access. You can view a recent-calls list, showing the source and target of the last 20 transmissions with the time and date information.
