Entel DT985M UHF ATEX IIC OLED Walkie-Talkie

Product description

Entel DT985M: ATEX IIC UHF communication for demanding maritime environments

Intrinsically safe for professional operations

The Entel DT985M is a UHF walkie-talkie from the DTEx Marine series, designed to maintain communications in maritime and industrial environments where intrinsically safe equipment is required.

Its ATEX II 2G Ex ib IIC T4 Gb classification allows it to be used in the potentially explosive atmospheres covered by this certification, provided that the applicable safety conditions are met.

The IIC gas classification is its main difference compared to the ATEX IIB models in the same range.

Analogue and digital communication in the UHF band

The equipment operates in the UHF band from 450 to 470 MHz and supports both analogue and digital operation, facilitating adaptation to different professional radio communication systems.

In digital mode, it offers 6.25 kHz and DMR communication options, subject to the relevant regulations and conditions of use. The manufacturer states that digital operation of this range is approved for the marine UHF band.

The transmission power of 1 W complies with its ATEX IIC classification.

OLED display for viewing channels

The high-contrast OLED display makes it easy to identify the selected channel and view operating information.

The unit can display the channel number and frequency, or the channel name and number, depending on the configuration used.

The robust controls and front-panel touch-sensitive buttons are designed to ensure reliable operation even when wearing gloves.

Clear audio in noisy environments

The DT985M incorporates noise reduction technology to ensure clear communications in high levels of ambient noise.

This feature is particularly useful during deck operations, port work and industrial activities where users need to convey instructions clearly.

IP68 protection for extreme conditions

Its marine- and industrial-grade construction is built to withstand demanding working conditions. The IP68 rating certifies resistance to submersion of up to 2 metres for 4 hours, in accordance with the manufacturer’s specified conditions.

It also meets the shock and vibration resistance requirements associated with MIL-STD-810 C/D/E/F/G, contributing to the device’s durability during professional use.

Its operating temperature ranges from -20 °C to +40 °C.

Battery life for long working days

The smart lithium-ion battery offers a specified battery life of up to 16.5 hours in analogue mode and 19.5 hours in digital mode, under a 5/5/90 duty cycle.

These figures allow for the planning of extended shifts, although actual battery life depends on operating conditions and the radio’s configuration.

Accessories and simplified programming

The Entel DT985M features a locking multi-pin accessory interface, designed to provide a secure connection with compatible accessories from the DTEx range.

The accessory validation system helps to maintain the equipment’s safety standards. It also features a Micro-USB connection that is protected against immersion.

Using the Entel PC programming application, it is possible to update the radio’s settings without the need for complex technical interventions.

Use cases and compatibility

The Entel DT985M is suitable for commercial vessels, port operations, industrial maintenance and work in potentially explosive atmospheres requiring an ATEX IIC-certified UHF radio.

Its analogue and digital operation allows it to be adapted to various compatible radio communication networks. It can be used with Entel DTEx accessories approved for the device, including certain microphones, headsets and professional communication systems.

The selection of channels, modes and accessories must comply with the applicable radio regulations and the safety requirements of each installation.
