The DTR650™ digital on-site portable radio delivers all the great features of the DTR550 along with managerial capabilities. The radio features operates at 900 MHz and offers enhanced communication options such as Digital One-to-Many Calling (Public Group Call and Private Group Call). It also provides enhanced performance with greater coverage — up to 350,000 square feet or 30 floors (with long whip antenna) — as well as longer battery life and digital audio quality that is clear and crisp within coverage areas.
Maintaining order and enhancing student safety are priorities for any
school. DTR Series™ radios keep everyone in touch—from teachers
and administrators to crossing guards and maintenance personnel.
That enables a quick response to any situation, often preventing
small problems from escalating into bigger ones.
Responsive service is essential to sales and customer satisfaction.
DTR Series radios make responsiveness easier to provide, whether
it’s an answer to a customer’s question, a price check, a clean-up
or an emergency. With clear, constant communication ensured,
customer satisfaction can be taken to the next level.
Success in industry depends on two things…efficiency and responsiveness.
Clear communication, often in noisy environments, is
essential to avoid downtime—and to enable the fastest response to
production problems or injuries. The DTR Series delivers. Its rugged
construction stands up to industrial environments, and its long battery
life meets the demands of overtime and multi-shift operations.
With DTR Series radios, building managers, maintenance
technicians, groundskeepers and security personnel can respond
fast to tenant needs or emergencies, minimizing costs and enhancing
Excellent service and customer satisfaction are the keys to loyalty
and repeat business. DTR Series radios keep your staff connected,
from the front desk and concierge to event planners and maintenance
personnel. That means a more productive staff and fast
response to guest needs, special events, spills and emergencies.
To keep any construction project on track, you need timely
coordination from management to foremen, subcontractors, and
individual tradespeople. DTR Series radios make it easy, helping
keep projects on schedule, avoid errors, meet deadlines and keep
costs on budget.
Digital One-to-One Calling
Allows you to 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 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 20 transmissions with time and
It all adds up to a superb combination of features for your convenience, management, and
productivity all at an extraordinary value.
