Channels The DT985 can be programmed with both analogue and digital channels, this 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 which gives significantly better audio, extended range and longer battery life in comparison to analogue radios.
Voice annunciationThis 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 DT985 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 socketDT985 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 DT885FF accessories incorporate a robust locking connector to further safeguard the safety of the user.
High contrast white on black OLED displaythe DT985 model benefits from a high contrast white on black OLED display that delivers superior readability in varying light conditions adding to the DT985’s intuitive user interface.
Li-Ion battery technology & improved talk timeDT985 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 AudioDT985 portables deliver loud & crisp audio no matter what environment you are in. All of the DT985'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.
Simple onboard reprogramming appWith our free, unique and simple to use PC app, you can easily re-program a DT985 radio whilst still onboard. The user friendly app makes it easy to drag and drop a new programming file from an email to your DT985 radio(s).
KeylockTo avoid accidental operation, your radio's keys & controls can be locked
Programmable channel monitor button If you have channel protection enabled on your DT985 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 DT985's speech tailoring technology delivering intelligible communications first time, every time
Scana programmable button allows channel scanning.
