Long Range Wireless RSM with Mobile Mic Bluetooth Gateway – No Charger

The Motorola Long Range Wireless Remote Speaker Microphone Kit (RLN6552B) is a professional wireless audio solution designed for users who depend on a high-power Motorola mobile two-way radio but frequently need to work outside of their vehicle. Combining a wireless Remote Speaker Microphone (RSM) with a Mobile Microphone Bluetooth Gateway, the RLN6552B allows workers to stay connected to their vehicle-mounted radio without being physically tethered to the vehicle.

The RLN6552B provides an impressive wireless operating range of up to 100 meters (approximately 328 feet) line-of-sight from the mobile radio. This extended range makes the system especially valuable for utility crews, transportation personnel, construction teams, public works employees, and other mobile workers who regularly leave their trucks or service vehicles while still needing immediate access to radio communications.

Motorola designed the system for fast and straightforward deployment using touch pairing between the Wireless RSM and the Bluetooth-enabled Mobile Microphone Gateway. Once the gateway microphone is connected to the compatible mobile radio, users can align the wireless microphone with the designated pairing point and use voice prompts to complete the connection. The plug-and-play design allows the wireless system to be set up in seconds without complicated pairing procedures.

The Wireless RSM provides the familiar controls users expect from a professional Motorola speaker microphone, including fast Push-to-Talk operation, volume control, a task light, and a large protected emergency button. Its omnidirectional microphone and integrated speaker allow the user to communicate naturally while remaining away from the vehicle-mounted radio.

Built for professional field use, the Wireless RSM features an IP55 rating with the dust cover closed and is tested to MIL-STD-810F standards for shock and vibration. The removable rechargeable lithium-ion battery supports extended operating periods, making the system suitable for long work shifts and demanding field operations.

The RLN6552B kit includes the Wireless Remote Speaker Microphone with battery and the Mobile Microphone with Bluetooth Gateway, but does not include a charger. A compatible Motorola vehicular or desktop charger must be purchased separately when required. This configuration is especially useful for organizations that already have compatible charging equipment or want to select a charging solution separately.

Important: The RLN6552B is not compatible with Motorola MOTOTRBO Connect Plus mode of operation. Organizations operating Connect Plus systems should verify system compatibility before purchasing.
