DTEx Series
Intrinsically Safe Land Portables

The ultra durable DTEx Series is the latest addition to our range of Intrinsically Safe radios. The rugged DTEx delivers exceptionally loud audio coupled with outstanding audio clarity and the ergonomic controls are specifically designed for gloved hand use. By combining the latest DMR digital technology with the highest Atex gas group ratings the DTEx series delivers best in class range, safety and reliability. Exceeding MIL-STD-810 and a market leading IP68 rating (2-meters 4-hours) the fully submersible DTEx can be depended on to withstand the most extreme and hostile of environments.

Simple to Advanced Configuration
The fully featured and versatile DTEx radios can be configured for simple press to talk operation or the more advanced features that you'd expect of a high tier two way radio. You can even customize the hi-contrast OLED display to show either basic large character display or more detailed information.
Superior Audio
Using the latest noise reduction technology Entel's DTEx portables deliver loud & crisp audio no matter what environment you are in. All of the DTEx range of accessories incorporate a robust locking plug and high-grade cable and benefit from Entel's proprietary "Smart Speech Tailoring" technology. This automatically detects the type of accessory connected and optimizes the audio accordingly to deliver the very best performance.

Safety Features You Can Rely On
DTEx radios support Digital mode Lone-Worker, Man-Down* and Emergency Button features with call interrupt. This, dealer programmable, 3 levels of safety ensures an alarm is raised as soon as is possible (even if the channel is already busy). *optional

IP68 2 Metres, 4 Hours Submersible
The DTEx Series offers the highest submersibility rating of any manufacturer. This protects against corrosion, withstanding total immersion in water to a depth of 2 metres for 4 hours to protect against the likely hazards encountered in wet environments.

Intrinsically Safe
ATEX Approved IIC - The DT900 series of ATEX certified portables meet IIC T4 - the most stringent ATEX ratings as per EU directive 94/9/EC.
ATEX Approved IIA - For those users not restricted to the IIC 1 watt regulatory classification, the DT800 series of ATEX certified portables meet IIA T4 with 4 watts of transmitter power.
IECEx Approval - The DT500 series of intrinsically safe certified portables are suitable for those users who do not need to comply with the European ATEX standard. (Outside Europe).

Migrate to Digital Your Way
DTEx radios utilize both Analogue and DMR Digital technologies. Supporting both technologies ensures backwards compatibility with existing Analogue radio systems and a simple migration path to the many benefits of Digital communications.
Intelligent Batteries, Audio Accessories & BA Support
Entel's intelligent batteries and accessories are designed to deliver optimum performance and safety. In Digital mode the battery endurance on DT900 radios is more than 18.5 hours from a single charge!
A vast range of Entel original audio accessories is available from a simple earpiece to bone conductive options for extremely high noise environments. In addition, 3rd party Breathing Apparatus comms kits are also supported.
Entel's Sure SpeechTM intelligent speech tailoring technology optimises audio to match the connected accessory, ensuring the very best clarity, volume and natural sounding audio.

Simple End User Programming
With Entel's unique and simple to use FREE PC app there is no longer any need for a user to return a handset to their dealer to re-program or update. With the user friendly app you can simply transfer programming data, future proofing software updates or add new features to your DTEx radios.
High Grade Accessory Interface
The rugged, multi-pin interface and Micro-USB socket are both submersible and gold-plated to minimise any risk of damage and protect against corrosion.
To ensure the integrity of IS protection levels any accessory connected to the handset automatically undergoes a validation process to safeguard against noncompliant accessories being used.
All DTEx accessories incorporate a robust locking connector to further safeguard the safety of the user.

Why digital?
· Better coverage · Significantly louder and clearer audio · Longer battery life, longer duty cycles · Far superior privacy
DMR is split into three types of service, from short-range license free to National I International connected networks:
Tier 1 - Tier 1 is for commercial and leisure use with direct mode operation (no repeaters allowed), fully approved for use within Europe and no license is required.
Tier 2 - Tier 2 is for small to medium size licensed systems. Radios can be used in direct mode or with a repeater if significantly extended range is required. Tier 2 repeaters can be networked to increase the coverage area even further.

Double the Channels
Using two slot simplex the DTEx radios split each channel in two, delivering double the number of Digital Channels at no extra cost. For example, if you are using a single analogue channel, the same channel in digital mode will yield two channels.
