Entel DTEx Series

Intrinsically Safe Commercial Marine Portables

Business Critical Communications

The DTEx Series is available in either VHF or UHF display and non-display models, setting the benchmark for next-generation onboard intrinsically safe portables. Standard features include both analogue and digital* modes of operation, a high visibility OLED display, high torque ergonomic controls designed for gloved-hand use, and an industry-leading IP68 2m 4 hours submersible rating, providing 100% reliability and usability even in the most extreme conditions.

Loud and Clear Audio

The DTEX Series delivers loud and intelligible audio, essential when working in high ambient noise environments. The accessory range incorporates a robust locking plug, high-grade cable, and intelligent speech tailoring technology that automatically optimises the audio for the type of accessory connected, always ensuring the best performance.

IP68 2 Metres, 4 Hours Submersible

The DTEx Series delivers a class-leading IP68 2 metres for 4 hours submersible rating, the highest IP rating of any manufacturer. This rating ensures protection against corrosion and likely hazards encountered in life at sea.

Intrinsically Safe Approved

  • ATEX Approved IIC - The DT900 Series of ATEX certified portables meet the IIC gas group, the most stringent ATEX rating as per EU Directive 2014/34/EU.
  • ATEX Approved IIB - The DT800 Series of ATEX certified portables meet IIB gas group.
  • IECEx Approval IIB - The DT500 range of intrinsically safe certified portables are suitable for those users who do not need to comply with the European ATEX standard.

Voice Annunciation (non-display models only)

This programmable feature is available on non-display models only. It assures the user that they've selected the correct channel, allowing them to focus on the task at hand. This feature also gives confirmation of button settings, e.g. 'Keylock On', 'Keylock Off', battery level status, and warns the user when the battery is low.

Easily Reprogram your radios...even at sea!

With Entel's free, unique, and simple-to-use PC app, you can easily reprogram a DTEx radio whilst still onboard. The user-friendly app makes it easy to drag and drop a new programming file, sent from your Entel Dealer by email, to your DTEx radio(s). This simple and intuitive process can be carried out by non-technical personnel.

Benefits of Digital

Aside from the exceptional audio, you will also benefit from increased usable range with no degradation of quality or interference. There are two digital modes: 6.25KHz Digital and DMR (see table below). DTEX Series can uniquely be programmed to operate in either of the digital modes or analogue mode. Digital operation is only approved for use on the UHF marine band.

Mode Vessel Flag VHF or UHF
Analogue EU and non-EU VHF or UHF
6.25KHz Digital EU and non-EU UHF
DMR Digital non-EU UHF

Industrial Grade Construction

Every aspect of the DTEx radio industrial grade design has been meticulously considered, from the high contrast OLED display, readable in all light conditions, to the high torque controls and the ultra-tactile front buttons that ensure reliable operation even when using gloved hands.

Intelligent Batteries

Entel's intelligent Lithium-ion batteries are designed to deliver optimum performance and safety. In digital mode, the duty cycle of the DT900 radios is more than 18 hours from a single charge!

Extensive range of accessories

From headsets to speaker microphones and advanced bone conduction technology, Entel offers a complete portfolio of accessories to ensure you stay connected.

High-Grade Accessory Interface

The rugged, multi-pin interface and Micro-USB socket are submersible and gold-plated to minimise any risk of damage and protect against corrosion. To ensure the integrity of intrinsically safe protection levels and safeguard against non-compliant accessories usage, any accessory connected to the handset automatically undergoes a validation process. All DTEx accessories incorporate a robust locking connector to safeguard the user further.
