RM780 IMPRES IP68 HAZLOC Remote Speaker Microphone with Radio Controls

Control essential radio functions and communicate clearly in demanding environments with the Motorola RM780 IMPRES Remote Speaker Microphone. Its powerful 102-phon speaker helps users hear radio traffic over crowds, machinery, vehicles and emergency-scene noise.

The RM780 places frequently used controls directly on the microphone, including a glove-friendly push-to-talk button, top-mounted volume control, orange emergency button and two programmable side buttons. This allows users to operate key radio functions without reaching for the radio.

Motorola Wind and Water Shielding technology helps reduce interference from wind and severe weather. The IP68-rated housing is tested for immersion at up to two meters for four hours, while Work-When-Wet drainage helps the microphone continue delivering clear audio following water exposure.

A standard, non-threaded 3.5 mm audio jack supports compatible receive-only earpieces for discreet communications. The PMMN4128A is also HAZLOC approved for use as part of a properly configured Motorola intrinsically safe radio system.
