The Motorola DTR550 use digital technology to provide benefits never before available in on-site two-way radios. Most important is the ability to call individual radios (digital one-to-one calling) and defined groups of radios as well as all DTR Series™ radios within range (digital one-to-many calling). The digital series provides greater coverage than comparable analog radios. Up to 300,000 square feet or 25 floors indoors with extended antenna that is included. 

The DTR550 meets U.S. Military 810 C, D, E and F specifications and Motorola standards for durability and reliability. Plus the DTR550 is affordably priced and offer exceptional value. Range is not a problem with the Motorola DTR series. Typically, the DTR550 provides 20% more coverage than a standard UHF two way radio. As with all 2-way radios, coverage will vary based on terrain and conditions - see our "2-Way Tips" for more info.

Motorola DTR550 two way radio uses 900 MHz digital frequency hopping technology to ensure crisp, clear and private communications. This technology uses a different set of frequencies than standard two way radios and can be used without purchasing a license. The silent vibrate feature allows stealth operations when it is best for quiet notification, this works great with the text SMS features.

The Motorola DTR550's enhanced text display even shows you exactly who is calling with its caller ID feature. Enhanced call forwarding allows you to automatically notify a caller that you are unavailable and forward their call to another radio. As an added convenience, the DTR550 is capable of sending and receiving 5 preset text messages, such as "I'll call you back in 5 minutes" and allows for keyed-in custom messages. DTR550 also allows you to define up to 20 groups. Call an entire group at once, like with standard radios, or you can call an individual radio.

Because the digital technology of the DTR550 enables each unit to have its own unique 11-digit identification, you get a new level of radio communication versatility. The DTR550 is capable of sending and receiving 10 preset messages, It also allows for keyed in custom messages to meet more specific needs.

The newly enhanced Motorola DTR550 with VIBRACALL is easily programmed with Customer Programming Software (CPS), which supports front panel programming and cloning with optional cable. Enable DTR Short Messaging Service (SMS) – a PC tool which allows users to text message a fleet. You can download the CPS Software HERE.

The digital performance of the DTR550 enables you to build bridges that expand the capabilities of individuals and teams, enabling them to get the job done right, fast and safely. That means powerful productivity that's perfect for your business, office or school.
