Channels - The DX582M-IS Marine can be programmed with both analogue and digital channels, which is clearly indicated on the display together with the frequency. If a semi duplex channel is programmed the word “Repeater” will be displayed instead of the frequency.

Benefits of digital - Digital mode gives significantly better audio quality, extended range and longer battery life in comparison to analogue radios.

Voice annunciation – This programmable feature announces either the channel position selected or a marine channel number (alias) – this gives further assurance to the user that they’ve selected the correct channel allowing them to focus on the task in hand.

Environmental protection to IP68 (2 Meters for 4 hours) - The DX582M-IS offers the highest submersibility rating of any manufacturer. This protects against corrosion, withstanding total immersion in water to a depth of 2 meters for 4 hours to protect against the hazards encountered in extremely wet environments.

Robust accessory socket – DX582M-IS accessory socket has been specifically designed so that when an accessory is secured to the portable, the connection can withstand use in a robust environment with punishment from simple dropping to careless misuse. The rugged, multi-pin interface and Micro-USB socket are both submersible and gold-plated to minimize any risk of damage and protect against corrosion. To ensure the integrity of Intrinsically Safe protection levels any accessory connected to the handset automatically undergoes a validation process to safeguard against non-compliant accessories being used. All DX582M-IS accessories incorporate a robust locking connector to further safeguard the safety of the user.

Li-ion battery technology & improved talk time – DX582M-IS radios are supplied with the latest intelligent Lithium-ion battery technology as standard. One key advantage of Lithium-ion battery technology is the way it eliminates ‘memory effect’, meaning that there is no need to fully discharge your battery before recharging. As a result of this, you are assured of a full charge each and every time you take your Entel battery from its charger.

Superior Audio - DX582M-IS portables deliver loud & crisp audio no matter what environment you are in. All of the DX582M-IS's compatabile accessories incorporate a robust locking plug and high-grade cable featuring Entel’s proprietary “Smart Speech Tailoring” technology. This automatically detects the type of accessory connected and optimises the audio accordingly to deliver the very best performance.


Simple on-board reprogramming app - With our free, unique and simple to use PC app, you can easily re-program a DX585M-IS radio whilst still on-board. The user friendly app makes it easy to drag and drop a new programming file from an email to your DX585M-IS radio(s).

This is a simple and intuitive process that can be carried out by non-technical personnel.

Keylock - To avoid accidental operation, your radio's keys & controls can be locked.

Programmable channel monitor button - If you have channel protection enabled on your DX585M-IS portable, all signals other than your own networks will be filtered out. This can be temporarily disabled allowing you to monitor all signals on your channel.

Audio Accessories - Entel offer an extensive range of accessories, most popular for Fire Fighters is the CXR bone conductive throat and skull microphones which eliminate ambient noise, further enhanced by DX585M-IS's speech tailoring technology, together delivering intelligible communications first time, every time.

Scan - a programmable button allows channel scanning, allowing you to keep in contact with other users across your network.
