Motorola yesterday announced the introduction of the MTP750, a TETRA-based portable radio that integrates voice, data and encryption functions with multiple language support in English, traditional and simplified Chinese, the company said. The MTP750 also offers improved ergonomics, more “intuitive” usage and faster response times, the company said. The MTP750's four-way “game-pad-like” navigation pad enables instant access to the radio’s menu and faster scrolling, as well as a compact talk-group knob that prevents accidental re-adjustment, enabling the user to stay in the selected talk group, according to Motorola. In addition, the MTP750 offers an enlarged emergency button that is designed and located so it can be triggered in “no-look” situations, Motorola said.
