General

Channels - This non display VHF marine portable can be programmed with up to 16 channels.

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 DT542 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 likely hazards encountered in extremely wet environments.

Robust accessory socket – DT542 accessory socket has been specifically designed so that when an accessory is secured to the portable, the connection can withstand any amount of punishment; from 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 IS protection levels any accessory connected to the handset automatically undergoes a validation process to safeguard against non-compliant accessories being used. All DT542 accessories incorporate a robust locking connector to further safeguard the safety of the user.

Li-Ion battery technology & improved talk time – DT542 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 - DT542 portables deliver loud & crisp audio no matter what environment you are in. All of the DT542's 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.

 

Convenience

Simple onboard reprogramming app - With our free, unique and simple to use PC app, you can easily re-program a DT542 radio whilst still onboard. The user friendly app makes it easy to drag and drop a new programming file from an email to your DT542 radio(s).

This is a simple and seamless 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 DT542 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 & BA Support - Entel also offer an extensive range of accessories including Draegor BA, most popular for Fire Fighters is the CXR bone conductive throat and skull microphones which eliminate ambient noise, further enhanced by DT542's speech tailoring technology delivering intelligible communications first time, every time

Scan - a programmable button allows channel scanning.
