Long Range Wireless RSM with Mobile Mic Bluetooth Gateway & Vehicular Charger

The Motorola Long Range Wireless Remote Speaker Microphone Kit with Vehicular Charger (RLN6551B) is a professional wireless communications solution designed for users who rely on a Motorola mobile two-way radio but frequently need to work outside of their vehicle. Combining a Long Range Wireless Remote Speaker Microphone (RSM), Mobile Microphone Bluetooth Gateway, and vehicular charger, the RLN6551B provides a complete in-vehicle solution for maintaining radio communications while working away from the driver's seat.

The RLN6551B provides a wireless operating range of up to 100 meters (approximately 328 feet) line-of-sight, allowing workers to communicate through their vehicle-mounted mobile radio while performing tasks outside the vehicle. This extended range is especially valuable for utility crews, transportation personnel, construction teams, public works employees, maintenance technicians, and other mobile professionals who regularly move between their vehicle and nearby work areas.

Motorola's Mobile Microphone Bluetooth Gateway connects to the compatible mobile radio and establishes the wireless link with the Remote Speaker Microphone. Simple touch-pairing technology allows the Wireless RSM to be paired with the gateway quickly, while voice prompts help guide users through the connection process. Once paired, the RSM provides convenient access to radio communications without a physical cable connecting the user to the vehicle.

The Wireless RSM provides the familiar controls professionals expect from a Motorola speaker microphone, including a prominent Push-to-Talk (PTT) button, integrated speaker and microphone, volume controls, a task light, and an emergency button. This allows employees to carry essential radio functionality with them while their more powerful mobile radio remains securely installed in the vehicle.

Built for demanding professional environments, the Wireless RSM features a rugged construction designed for field use. Its rechargeable battery supports extended operating periods, while the wireless design eliminates the restrictions of a traditional corded mobile microphone when employees need to exit the vehicle and continue communicating.

Unlike the RLN6552B configuration, the RLN6551B includes a vehicular charger for the Wireless RSM. The charger allows the microphone and battery to be conveniently charged inside the vehicle, helping ensure the RSM remains ready for use throughout the workday. This makes the RLN6551B an excellent all-in-one configuration for organizations deploying the long-range wireless system in fleet vehicles.

Important: The RLN6551B is not compatible with Motorola MOTOTRBO Connect Plus mode of operation. Organizations operating Connect Plus systems should verify their radio and system configuration before purchasing.
