Advanced Tactical Control for Mobile Radio Systems

THIS PRODUCT IS EOL (END-OF-LIFE)

The Icom HM221T is a high-performance mobile speaker microphone specifically engineered for the F5400D and F7500 series digital mobile radios. In demanding public safety and industrial dispatch environments, the ability to perform complex tasks directly from the microphone is essential. This microphone solves that need by integrating a full DTMF keypad, allowing operators to make private calls, access telephone interconnects, and send numeric commands without reaching for the radio main-unit. This product is no longer available, the replacement product is the ICOM HM220T

Equipped with an IP55 weather-resistance rating, the Icom HM221T is built to withstand the moisture and dust exposure common in vehicle-based operations. It features a dedicated emergency button on the top of the housing, providing a critical safety lifeline that allows users to trigger a distress signal instantly. With its heavy-duty coiled cord and reinforced waterproof plug, this microphone ensures that your mobile communication remains clear and functional even in the most punishing field conditions.
