Small, Slim and Smart
New engineering techniques including the use of a custom SoC (System-on-a-Chip) and flat sheet keypad have made ra- dios body as compact as possible. The slim dimensions are also supplemented with reduced power consumption, allowing for a thinner battery pack.
DES/AES Encryption with OTAR
For digital communication security, the radios provide basic 4-key DES encryption as standard. When used with the op- tional UT-134 encryption unit, 256-bit AES encryption and the OTAR function are available. The OTAR function allows updat- ing of encryption keys over the radio channel.
High-Resolution Color LCD
The high-resolution transreflective colour LCD provides great visi- bility in both natural and indoor lighting. Functions and menu items are clearly labelled with easy to read. A night mode LCD setting is an available for use at night or in low lighting conditions.
OTAP and OAA
For efficiency in radio programming, the OTAP (Over-the-Air-Program- ming) function allows remote change of programming data (for ex- ample adding a new repeater) over the radio channel. The OAA (Over- the-Air-Alias) function sends user name over the radio channel and eliminates needs to program the alias table. Successfully manage your fleet with ease.
Multiple Languages
Functions and menu items can be shown in local languages in- cluding English, French, German, Spanish, Russian and Sim- plified Chinese fonts. In addition, voice announcements can be recorded and changed for output in these languages.
Built-in Bluetooth®
The built-in Bluetooth module provides remote operation and hands-free communication paired with a third-party Bluetooth headset*. When connected with Bluetooth telemetric devices or PC terminals, data or files can be wirelessly transferred. * Available functions depend on paired Bluetooth devices.
License Key Upgrade
The radios functions and protocols can be upgraded and custom- ized to meet your specific needs with various license key options.
