Environmental protection to IP55 
The practical HX Series 2.0 radios enjoy an IP55 rated construction, which means that they are dust protected and resistant to water ingress (i.e. splash proof). For most day to day applications, this level of protection is perfectly adequate, however, where full protection against immersion in water is required, users should consider our IP68 rated HT Series 2.0 radios.
 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.
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.
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.
Robust accessory socket
