Submersible to IP68 (5 metres for 1 hour)

Entel is the first manufacturer to offer the superior IP68 specification, whereby we ourselves determine at what depth and for how long our equipment must remain waterproof. Not content with just the standard IP67 entry-level (1 metre for 30 minutes) Entel's IP68 HT series is certified as waterproof-submersible to an unprecedented depth of 5 metres for 60 minutes.

Aware that the smallest tolerances of case size and material variation alone could compromise your radio's waterproof integrity, uniquely, each individual Entel portable is tested on a custom-built air pressure test-jig to ensure it meets the exacting high standards we have set for ourselves. See the video.

     MILSTD 810C/D/E/F

Meeting MIL-STD 810C/D/E/F commercial grade construction for tough, enduring performance, the Entel's HT and HX series 2.0 portables conform to stringent standards, enabling them to withstand the everyday rigours of shock, vibration and the corrosive effects of dust and moisture, ensuring many years of trouble free use in the most hostile environments. See the video.

     1800mAh Li-Ion battery

All Entel portables come with the latest intelligent Lithium-Ion battery technology as standard. Whichever model you choose, these batteries will count the number of completed charge cycles, which on LCD variants, if dealer enabled, can be displayed when you power-on your radio. For your convenience it will even alert you to imminent battery life expiration. Another advantage of Lithium-Ion battery technology is the way it maximizes duty cycles, while the elimination of memory effect means there is no need to fully discharge the cells before recharging. Therefore you are assured a full duty cycle each and every time you take your radio from its charger.

     Low battery alert

When you do eventually use almost all the charge in your battery your radio will conveniently let you know it is time to change or recharge your battery.

     Flash upgradeable to add future features

Entel proposes to continuously add/upgrade features to its range of radios. Using Flash Upgrade technology your radios can be upgraded by your Dealer at any time. For the latest range of features please see our Support pages.

     All INT, USA and CAN channels

The HT644 is supplied preprogrammed with all INT, USA and CAN channels.

     Robust accessory socket

A completely redesigned accessory connector, when secured to the portable, is designed to withstand any amount of punishment from dropping to careless misuse. Furthermore, the securing bolt incorporates a shearing point to protect the connector. See the video.

     Scrolling graphic LCD display

LCD display variants offer more information and versatility. For example, our high tier radios can display: channel name, caller ID, text messages, emails etc.

     7-Key keypad

The 7-Key keypad gives you direct access to functions such as channel scanning, weather channels and channel 16.

     Voice annunciation (option)

Speaks the channel number and basic settings so you can operate the radio without having to look at it.

     Bluetooth™ wireless communications (option)

Allows you to connect a Bluetooth audio or data accessory.

     Programmable scrambler (voice inversion)

The variable point inversion scrambler protects against casual eavesdropping. This can also be dealer programmable to give compatibility to other manufacturers' portables with built in scramblers.

     VOX hands free (with audio accessory)

When you attach a VOX enabled audio accessory you can operate totally hands free. All you need to do is talk and your Entel radio will automatically transmit for you.

     Battery charge count

Whichever model you choose, these batteries will count the number of completed charge cycles, which on LCD variants, if dealer enabled, can be displayed when you power-on your radio. For your convenience it will even alert you to imminent battery life expiration. If you opt for a system of non-display portables then we recommend that you have at least one model with a display in order to take advantage of this unique feature.

     Invert display

Turns the display output upside down allowing you to read the display when the radio is viewed upside down.
