Product features:
DMR – analogue and digital DMR Tier II/III operation with AES256 encryption support and wrong battery alert 
Full numeric keypad with 6 programmable buttons and a 1.7" (132 x 90 px) color display 
ATEX/IECEx intrinsically safe certified for Gas Zone 1/21, Zone 2/22, Dust IIIC, and Mining M2 hazardous environments 
Advanced audio architecture with a 2.5 W speaker, Dual Click volume control with Volume Boost (up to 108 phons), and AI noise suppression 
Rugged construction certified to ATEX IP66/IP68 (submersion up to 2 m for 2 hours) and disinfectant-resistant housing • Product description
The MOTOTRBO R7Ex FKP is engineered to provide maximum safety for personnel working in high-risk, potentially explosive environments. Fully certified to ATEX and IECEx standards, it prevents potential ignition risks when flammable gases, vapors, mists, or conductive dusts are present. Its distinctive blue accents allow immediate visual identification of ATEX-safe devices in the field, while a built-in sensor alerts users if a non-ATEX battery is attached.
Equipped with a full numeric keypad and a crisp 1.7" color screen, the R7Ex FKP enables workers to compose freeform text messages, manage contact lists, and utilize Text-to-Speech readout. Designed for extreme noise, its 2.5 W speaker with dynamic Volume Boost delivers speech loudness up to 108 phons. AI-trained noise cancellation filters out heavy machinery, fan, and pump background noise.
The R7Ex FKP undergoes stringent ATEX IP66 and IP68 testing, including thermal endurance and impact conditioning before water submersion tests. Worker protection is reinforced through Fall Alert (Man Down), Lone Worker, a prominent emergency button, and location tracking via GNSS and Bluetooth 5.2. Integrated Wi-Fi supports over-the-air programming (OTAP) and seamless integration with ATEX-certified headsets.
The MOTOTRBO R7Ex FKP portable radio is designed for chemical engineers, maintenance technicians, process operators, and emergency responders in hazardous environments requiring text input and ATEX compliance.
Oil & gas operations & refineries: intrinsically safe communication across Gas Zone 1 / Zone 21 areas with worker tracking.
Chemical & pharmaceutical manufacturing: easy text messaging via full keypad and disinfectant-resistant casing.
Mining & heavy processing: dust-tight performance in conductive dust environments with loudness up to 108 phons.
