rating, to provide 100% reliability and usability even in the most extreme
conditions.

loud and intelligible audio, essential when working in high ambient noise
environments.

selected the correct channel allowing them to focus on the task in hand.

DTEx UHF radios support both analogue and digital technologies. Supporting
both technologies ensures backwards compatibility with existing analogue radio
systems and a simple migration path to the many benefits of digital
communications.

performance and safety. In digital mode the duty cycle of the DT900FF radios
is more than 18.5 hours from a single charge!

popular for Fire Fighters is the CXR bone conductive throat and skull
microphones which eliminate ambient noise, further enhanced by DTEx’s speech
