Ready for work sites

The two-pack delivers two Motorola RMU2040 radios built for security, maintenance, distribution and construction crews who need reliable voice communication across a 250,000 square-foot area. Each unit operates on 99 UHF business-exclusive frequencies with 219 PL/DPL codes, including six customizable options. The 1500MW speaker cuts through high-noise environments without feedback. No display or keypad keeps operation simple in harsh conditions.

Drop-in charging and hands-free kit

Each radio ships with a rechargeable lithium-ion battery, drop-in tray charger, power supply and belt holster so the devices are ready for a full shift without extra wiring. The bundle adds two HKLN4604 swivel earpieces with in-line microphones and push-to-talk buttons, letting staff communicate discreetly while keeping hands free for tools or machinery. A microphone cleaning spray is also included for hygiene maintenance.

Military-grade sealing for sustained use

The chassis meets military specifications for resistance to dust, wind, shock and vibration, so performance stays consistent through long days on construction sites or factory floors. The fixed 1500MW audio output maintains clarity during extended transmissions rather than fading under thermal load. FCC ID AZ489FT4913 confirms narrowband compliance for ongoing regulatory use. Buyers needing VHF bands, trunking protocols or GPS tracking should consider other platforms.

The 1500 mW speaker is built for noisy industrial environments and the rugged chassis meets military specs for heat, dust and vibration during extended use.

Yes, each swivel earpiece with in-line microphone and push-to-talk connects directly to the radio's accessory port — no extra adapters required.
