Hands-Free Remote Push-to-Talk Foot Switch
Heavy-Duty Floor-Mounted Mobile Radio PTT Controller
Keep your hands safely on the steering wheel and maintain absolute control over your fleet dispatches with a rugged vehicle floor-mounted PTT pedal switch.
The genuine Motorola RLN4856A is a commercial-grade Motorola RLN4856A Remote Push-to-Talk Foot Switch for CM200D mobile transceivers engineered to maximize driver safety and operating focus. Integrating the Motorola RLN4856A into your commercial or public service vehicle layout allows operators to instantly engage system transmission lines without taking their hands off primary steering controls or heavy machinery joysticks. This vehicle accessory features a heavy-duty mechanical foot pedal actuator designed to withstand repeated hard stomping in rough field environments. The Motorola RLN4856A is the updated version of the Motorola RLN4856.
Perfect for long-haul logistics drivers, waste management operators, public transit captains, and utility repair crews, the Motorola RLN4856A resolves the critical safety hazard of fumbling for a handheld mobile microphone while navigating active traffic or rugged worksites. Hardwiring directly into the accessory port matrix located on the rear chassis of compatible mobile transceivers, it anchors firmly down onto the vehicle’s floorboard. Pairing this remote foot switch assembly with an overhead visor microphone transforms any cab into a completely hands-free, high-productivity mobile workspace. For optimal performance, pair the RLN4856A with the Motorola GMMN4065 omni-directional visor microphone to unlock the full potential of your communication setup.
The durable internal micro-switch mechanism provides crisp tactile and acoustic feedback to ensure the operator knows precisely when the radio line is active. The out-of-the-way floor routing shields the heavy-gauge interface cable from snagging loose gear or interfering with the driver's standard pedal cluster. When installing the component, always route the wire harness away from high-heat zones and moving steering column shafts to prevent mechanical shearing or jacket insulation melting over long-term usage cycles.

Frequently Asked Questions
Can I use this foot switch concurrently with a standard handheld mobile microphone?
Yes, the rear-accessory port mapping generally allows the foot switch to operate parallel to a front-mounted palm mic, meaning you can use the pedal to transmit via an overhead visor mic while leaving the standard palm microphone available for alternative crew use.
Does this foot pedal assembly require specialized programming software to activate?
In most standard mobile radio configurations, the rear accessory pins for external PTT are plug-and-play. However, some advanced models may require checking your radio's customer programming software (CPS) to ensure the accessory port logic is mapped to "External PTT."
Is the housing waterproof enough to handle wet and muddy work boots?
Yes, the Motorola RLN4856A is ruggedized for low-level floor environment deployment, meaning it easily repels mud, water drops, and debris tracked into a vehicle cab. However, it should not be subjected to pressurized washdowns or left submerged in standing water.
