MTP6550 TETRA Rugged Portable Radio

Designed for tough environments, the MTP6550 ensures communications availability through a rugged, water-submersible design. The radio also provides unmatched communications clarity, ensuring minimum audio distortion even at high volume through the in-built speaker or an attached remote speaker microphone.

A TEDS-ready radio, the MTP6550 offers comprehensive data connectivity and local storage options to provide mobile workers with on-demand access to critical information. With integrated Bluetooth, the MTP6550 allows users to connect an array of Bluetooth audio accessories and data devices without an external adapter.


Communications Lifeline

With best-in-class receiver sensitivity, operational range can be extended by up to 14%. With 2W audio through the loudspeaker as well as through the IMPRES remote speaker microphone, you can benefit from loud, clear and undistorted audio to ensure reliable communication.

Mission-critical Design

Frontline personnel need to trust their equipment. To ensure ruggedness our radios meet and exceed stringent MIL-SPEC test standards in addition to meeting the requirements of ETSI mechanical tests. In addition to optimized ergonomics, the MTP6000 series is IP67 compliant meaning it will continue to operate even after being submerged in water.

Harness Intelligence

Instantly share intelligence with frontline officers through TEDS data connectivity, flexible Bluetooth v2.1 wireless technology or using the micro SD card for multimedia content storage

Automate the Backoffice

Simply dock the radio in its charging cradle to seamlessly share evidential images and mission briefings between the radio and backoffice systems.
