Intrinsically-Safe digital DMR Two-Way Radio

Offering safe, reliable communications, the Hytera PD792i-Ex handheld digital radio with screen and full keypad has been designed to meet the European Atex directives, FM standards and IEC standards, perfect for tough environments that require advanced, intrinsically-safe devices.

Clear Communication

Thanks to the latest audio processing technology and in-built speaker, the PD792Ex offers you outstanding audio quality and noise cancelation


Innovative Construction

Both the radio and the battery are encapsulated to ensure that all internal connections are protected and sealed off from dangerous explosive gases and dust particles. The high-strength LCD is scratch and impact resistant


GPS Location

Positioning and tracking as standard, also including man down feature


Fail-safe Design

Batteries or accessories with a lower level of protection automatically trigger an alarm, whilst a patented latch ensures the battery remains securely attached even when knocked or dropped


Rugged and Reliable

Dust and waterproof, rated IP67, sustaining performance in harsh environments




Send a priority transmission to interrupt other calls, ideal for important, critical messages.


Using pseudo-trunking, a Hytera patented technology, slots can be shared to improve capacity usage with transmissions either direct to handset or to repeater


Combining noise cancelling technology to remove nusiance noise from the transmission, with powerful speakers to deliver clear communications


Enabling location based services to improve safety and control.


This feature allows the radio to switch between sites on Multi-site Conventional and XPT systems, ensuring seamless communication.


Raise an alarm with top priority to a base station or to other radios with the pre-programmed emergency mode, identifying the ID of the person issuing the alarm. Also receive emergency notifications.


The lone worker feature uses a timer in the radio to measure inactivity. If the timer expires, a warning is issued, and if there is no response to that, the alarm is triggered.


The man down feature will let you know if the radio has been tilted past a certain angle. This may happen for instance if the radio user has fallen over or is unconscious or injured. The alarm will be triggered after a warning is issued to the user
