radios on the same group ID and channel hear communications,
similar to analog radio operation.
• Private group call—enables you to program DTR Series radios to communicate with specific sets of
group members. Caller ID displays group identification.
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 DTR550 and DTR650 also feature:
• Short message service (SMS) text messaging—with ten preset messages (five on DTR550) for example,
“I’ll call you back in 5 minutes,” and support 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 also view
a recent-calls list, showing the source and target of the last 10 transmissions with time and date
information.
