General

Channels - The DT885FF Marine 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.

Environmental protection to IP68 (2 Meters for 4 hours) - The DT885FF 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 – DT885FF 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 display – the DT885FF model benefits from a high contrast white on black OLED display that delivers superior readability in varying light conditions adding to the DT885FF’s intuitive user interface.

Li-ion battery technology & improved talk time – DT885FF 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 - DT885FF portables deliver loud & crisp audio no matter what environment you are in. All of the DT885FF'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.

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 DT885FF 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.
