Entel DT885M ATEX IIB T4 DTEx DMR Digital UHF Marine radio

Entel designed the industrial-grade DTEx DMR Digital Series to meet the highest standards of durability and performance. This ATEX-certified portable radio is built for extreme environments, delivering exceptionally loud and clear audio, even in the harshest conditions. Its ultra-tactile buttons and high-torque controls ensure ease of use, even while wearing gloves.

The DTEx Series sets a new benchmark for onboard radios, offering a market-leading IP68 submersible rating, allowing it to be submerged up to 2 meters for 4 hours. This ensures reliability in hostile marine environments and under daily rigorous use.

The DT885M Marine model can operate in both analogue and digital modes, with 99 channels clearly indicated on the display, alongside the frequency. If a semi-duplex channel is programmed, the word "Repeater" will appear instead of the frequency, allowing users to differentiate easily.

Key benefits of digital mode include superior audio quality, extended range, and improved battery life compared to analogue radios. These features make the DT885M ideal for use in environments where reliable communication is essential.

The DT885M also provides the highest level of environmental protection, with its IP68 submersibility rating ensuring it can endure total immersion in water, safeguarding it against corrosion in extremely wet conditions.

Durability is a core feature, with the DT885M's robust accessory socket designed to withstand tough handling, ensuring a secure connection even under harsh conditions. Both the multi-pin interface and Micro-USB socket are submersible and gold-plated, minimizing the risk of corrosion. Additionally, the device automatically validates connected accessories to ensure compliance with IS protection standards, further enhancing user safety.

The high-contrast white-on-black OLED display offers exceptional readability in varying light conditions, making it easy to use in low visibility.

With the latest Lithium-ion battery technology, the DT885M delivers improved talk time and eliminates the ‘memory effect,’ ensuring a full charge every time without needing to fully discharge the battery. This provides up to 17 hours of operation in digital mode and 14 hours in analogue mode.

Superior audio is a hallmark of the DT885M, with clear, loud sound in any environment. The Smart Speech Tailoring technology optimizes audio based on the accessory connected, ensuring peak performance.

Reprogramming the DT885M is simple, thanks to the onboard PC app, which allows non-technical personnel to drag and drop programming files while still onboard. This makes updates seamless and user-friendly.

The keylock feature prevents accidental operation, and the programmable channel monitor button allows users to temporarily disable channel protection, enabling monitoring of all signals on the channel. The memory scan feature lets users create or modify their own scan lists, enhancing flexibility during operation.

Entel also offers a range of high-quality accessories for the DT885M, including Draegor BA and CXR bone-conductive microphones. These accessories, combined with Entel’s speech tailoring technology, ensure clear communication by eliminating ambient noise.

The DT885M is ATEX IIB T4 approved, meeting the strictest ATEX standards as per EU directive 2014/34/EU, making it safe for use in hazardous environments.
