Keeping operations running smoothly during a change in communication systems is vital to your operation. Now you can transition to digital with great confidence and low risk at a price you can afford. It’s easy to migrate because the XiR M6660 operates in both analog and digital modes. Analog and digital channels can be configured concurrently on the same radio, and scanning can be digital, analog or dual-mode. So you can use your existing analog system and move to digital when time and budget allow.

Connect More people, More productively

Whether your people are delivering packages or transporting students, you’ll appreciate our mobile’s easy scalability. All it takes is a simple software upgrade to add key features like transmit interrupt suite to prioritize critical communication.
And when you want to expand capacity or coverage, rely on IP Site Connect which uses the Internet to extend coverage to employees anywhere in the world.

Get durability that endures

The XiR M6660 is made to last. It is backed by a two-year standard warranty and a minimum one-year warranty for Motorola-branded accessories. It is rated IP54 (waterproof, virtually dustproof), so it can be used even in harsh environments. Moreover, the design has been proven tough in Motorola’s grueling Accelerated Life Test program, in which the radio must survive a simulated 5 years of hard service before it is accepted. You can be confident in the durability of your XiR M6660 radios.
