Motorola RMU2040 Radio

The RMU2040 delivers reliable coverage across up to 250,000 square feet or 20 floors indoors. For outdoor use, you can expect a range of 1–2 miles, depending on terrain and environmental conditions. This makes it well-suited for warehouses, construction sites, multi-floor office buildings, and large retail environments.

The RMU2040 comes with 4 channels, allowing you to organize separate teams or departments without signal overlap. Need more channels? Consider the RMU2080, which offers 8 channels for larger, more complex operations.

The RMU2040 operates on 99 UHF business-exclusive frequencies (450–470 MHz) and features 219 PL/DPL codes, including 6 customizable codes. These business-exclusive frequencies keep your communications private and interference-free—so your conversations stay between your team, not the entire job site.

Yes. Because it operates on UHF frequencies, the RMU2040 is designed to penetrate walls, floors, and other physical barriers—making it equally effective indoors and outdoors. UHF signals are ideal for environments with obstacles, such as warehouses, hospitals, and multi-story buildings.

The RMU2040 ships with a standard 2,150 mAh lithium-ion battery that delivers up to 12 hours of use per charge—enough to cover a full shift without interruption. Need more power for extended operations? The Ultra-High Capacity 3,200 mAh Battery extends runtime even further, giving your team more time between charges.

Every RMU2040 ships with a drop-in stand-up charging tray and wall charger—so your radio is always ready when your team is. For larger fleets, the Motorola PMLN6384 6-Unit Charging Tray keeps multiple radios powered and organized from a single station.

Built tough and proven durable. The RMU2040 meets Military Standard 810C/D/E/F/G and IP54/55 specifications—certifications that confirm its ability to withstand dust, moisture, vibration, and shock. Beyond industry standards, every RMU2040 undergoes Motorola's exclusive Accelerated Life Testing (ALT), which simulates up to 5 years of real-world field use, including:

• 30 minutes of blowing rain exposure on all surfaces
• 9 hours of continuous vibration testing
• 48 hours in a salt fog environment
• 6 hours of blowing dust exposure
• Temperature extremes from -67°F to 160°F In short: accidental drops, dust, and moisture are no match for this radio.

The RMU2040 is water resistant, rated to IP54/55. It handles rain, moisture, and humid environments without issue. However, it is not rated for submersion. If the radio is submerged, turn it off immediately and allow it to dry thoroughly before use.

Yes. The RMU2040 features an antimicrobial coating that helps prevent the growth of mold and germs on the surface of the radio. This is especially useful in shared-use environments—such as restaurants, medical offices, and retail settings—where multiple team members handle the same device across different shifts.

Yes. The RMU2040 features Advanced Voice Activation (VOX), which enables fully hands-free communication—with or without optional accessories. This is particularly useful for workers who need to keep their hands free while communicating, such as warehouse staff, construction workers, or event coordinators.

Yes. The RMU2040 supports NOAA Weather Radio alerts, allowing you to dedicate a channel to monitoring weather and receive automatic notifications when severe conditions are in the area. This is a valuable feature for outdoor teams and construction crews who need to react quickly to changing conditions.

Yes. The RMU2040 is compatible with Motorola's HTML-based Customer Programming Software (CPS), which allows you to customize channel assignments, frequencies, and advanced features such as channel announcements. To program your radios, you'll need the Motorola HKLN4027 Programming Cable. The CPS software is available as a free download from Motorola's website.

This feature lets users know exactly which channel they're on—without ever looking at the radio. Using the Customer Programming Software, you can assign each channel a custom announcement from 16 pre-recorded work functions (e.g., "Security," "Customer Service," "Cashier"). This eliminates confusion in fast-moving environments and keeps your team focused on the task at hand.

The RMU2040 is backed by a 2-year replacement warranty that covers defective or malfunctioning units. It's a reflection of how much confidence Motorola has in this radio's build quality.

• Earpieces: D-style, swivel, surveillance, and temple transducer options
