Motorola DM4601 Professional Mobile Radio | Durable DMR Digital Vehicle-Mounted Radio
Motorola DM4601 DMR digital mobile radio offers secure long-range communication for commercial fleets, retail, and public safety. Professional-grade design with reliable performance for daily operations.
Main features
DMR Tier 2 Digital
As a true DMR vehicle radio, the Motorola DM4601 doubles channel capacity with dual-timeslot TDMA technology, while delivering clear digital voice and integrated data—requiring no additional hardware. Analog/digital hybrid mode means no upgrades required.
45 Watts VHF / 40 Watts UHF Output Power
The high-power model delivers up to 45 watts of transmit power in the VHF band and up to 40 watts in the UHF band, providing communication range far exceeding any analog vehicle radio, ensuring workers stay connected even on highways or deep in quarries.
Intelligent Audio, Automatically Adjustable
Background noise suppression and automatic volume adjustment adjust in real time, so drivers no longer need to fumble for knobs when switching from a quiet cab to a noisy construction site.
Full-Color Day/Night Display
The 2-inch QVGA screen provides clear display of caller ID, SMS tickets, GPS coordinates, and channel icons even in bright sunlight or complete darkness—a feature unmatched by traditional Motorola car radios.
Integrated Bluetooth and GPS
Pair with wireless headsets for hands-free compliance or data transfer to tablets. Built-in GPS offers positioning accuracy of <5 meters for fleet tracking, geofencing, and Automated Vehicle Location (AVL).
Scalable Architecture – From Single Site to Nationwide
IP Site Connect, Capacity Plus, and Linked Capacity Plus allow you to scale from a single site to over 1,000 users across continents without replacing hardware, ensuring your Motorola mobile radio investment is future-proof.
MIL-STD-810 G and IP54 Protection Rating
Withstands temperatures from -30°C to +60°C, thermal shock, vibration, salt spray, and a 1-meter drop impact sufficient to damage typical consumer-grade radios. The cast aluminum casing also serves a heat dissipation function, ensuring continuous operation.
