Irving, TX – April 21, 2010 – EF Johnson Technologies, Inc. (NASDAQ: EFJI) announced today that it will unveil its new 51FIRE ES portable radio at the Fire Department Instructors Conference (FDIC) April 22-24 at the Indiana Convention Center in Indianapolis, Indiana.

“With the 51FIRE ES, we have designed and packaged a portable radio especially for the firefighting industry,” said Michael Jalbert, president and chief executive officer of EF Johnson Technologies, Inc. “After conducting market research, we developed a feature set that we believe meets the specific needs of firefighters with the primary focus on safe and reliable communications.”

“The 51FIRE ES includes standard features such as yellow housing, immersibility and a factory mutual intrinsically safe rating to withstand the extreme and hazardous conditions experienced by firefighters. Also, we are offering an upgrade to the new AMBE+2 v 1.6 Vocoder which substantially filters out background noise even in the presence of a personal alert safety system (PASS) and an intuitive out of range (OOR) feature that alerts a firefighter when out of communications range when used with EFJohnson’s IP25™ Conventional system,” Jalbert added.
