PD795Ex Intrinsically-safe digital two-way radio

Handheld | Handheld ATEX | DMR

Offering safe, reliable communications, the Hytera PD795 Ex handheld digital two-way 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.

Highlights of PD795Ex

PRIORITY INTERRUPT

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

PSEUDO TRUNKING

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

INTELLIGENT AUDIO

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

GPS

Enabling location based services to improve safety and control.

ROAMING

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

EMERGENCY MODE

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.

LONE WORKER

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.

MAN DOWN

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.
