The Jetfon JR-4011 (Y3) is a commercial-grade remote handheld speaker-microphone (RSM) engineered to deliver robust, high-clarity voice communications for professional two-way radio fleets. Enclosed in a high-impact, ergonomically contoured black composite casing, this heavy-duty accessory features a responsive side-mounted speech-listening key (PTT button) designed for rapid, low-latency transmission triggers. It serves as an essential field hardware asset for security personnel, tactical squads, and industrial plant coordinators who require immediate communications without removing their transceivers from utility belts.
Engineered to optimize field functionality, the JR-4011 (Y3) features a front-facing speaker acoustic grille carrying the official screen-printed Jetfon logo layout, paired with an integrated high-sensitivity electret microphone module. The chassis is outfitted with a high-resistance curly coiled cable extension to prevent physical wire strain during sudden operator movements. For operations requiring discrete monitoring, the lower casing houses an auxiliary earphone jack input protected by a secure rubber sealing flap. Terminated with a specialized multi-pin “Y3” type hardware connector, this model ensures a stable mechanical lock and low electrical resistance.
