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.
