General
Channels – The DT844FF VHF Marine can operate in either USA/INT/CAN modes or a simple custom channel line-up, for example; 6,16,15,17,69,72
Environmental protection to IP68 (2 Meters for 4 hours) – The DT844FF 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 – DT844FF 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 DT844FF accessories incorporate a robust locking connector to further safeguard the safety of the user.
High contrast white on black OLED display – the DT844FF model benefits from a high contrast white on black OLED display that delivers superior readability in varying light conditions adding to the DT844FF’s intuitive user interface.
Li-Ion battery technology & improved talk time – DT844FF 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 – DT844FF portables deliver loud & crisp audio no matter what environment you are in. All of the DT844FF’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.
