The Motorola i325 IS handset is billed as the first intrinsically safe phone for off-network use. A Direct Talk function lets users outside a Nextel coverage area manually transfer to a two-way radio-to-radio communication mode. The handset is approved for use where there may be flammable gases or vapors and also meets military specifications (810 B tests) for resistance to blowing rain, dust, shock, vibration, high/low temperatures and pressure, solar radiation, humidity, and salt fog. It has a rubber overmold, a sealed bottom connector cover to protect from liquid or dust damage, and a fixed antenna for durability. Java technology lets users run and download applications, and GPS is included as well.
