Highlights of PT790Ex

IA PROTECTION CLASSIFICATION

The whole radio with battery is designed to comply with the highest grade 'ia'. It can work in the places which contains various explosive gas and dust. It has passed ATEX, FM, IECEX certification.

STRICT PCB DESIGN AND HIGH EMC PERFORMANCE

To achieve high explosion-proof level, Hytera PT790Ex adopts optimal PCB layout design. All the key components of PCB are covered with shield which minimizes the circuit fault probability and has better performance of EMC.

PATENTED BATTERY LATCH DESIGN

To disengage the battery from the radio, you need to remove the lock and bolt of the latch along two different axes. Such a patented design ensures there is no disengagement of the battery pack from the main radio in case of dropping that might cause spark.

GNSS POSITIONING

The built-in GNSS module supports GPS, GLONASS, Beidou. Its tracking sensitivity is up to -164dBm, and its accuracy is within 2 meters.

MAN DOWN

When a user falls down, the radio can automatically alert others.

LONE WORKER

To ensure the safety of terminal users, the emergency function will be triggered automatically when there is no operation on the terminal within the predefined time period.

LONG CYCLE LIFE

Hytera PT790EX provides 1800mAh/2400mAh large capacity Li-ion battery, which can last for more than 20 hours under 5-5-90 duty cycle. Strict overcharge and overdischarge protection design ensure the battery against instability caused by overheating. In addition, the battery cells are also encapsulated to redistribute single point heat buildup and prevent air discharge as well.

RUGGED AND RELIABLE

PT790Ex is designed to comply with MILSTD 810G and IP67 Dust&Water Protection Rating, which ensures its best performance even in the toughest conditions and environment.

IOP

Hytera PT790Ex enables quick access to TETRA network and roaming, providing safe and efficient communication service. It also provides powerful interoperability with base stations and terminals of different manufacturers.

ENHANCED SPEECH PROCESSING TECHNOLOGY

Hytera PT790Ex adopts state-of-the-art speech processing technology to remove environment noise (ambient noise) and echo (acoustic&echo), which provides users with clear voice communication even in a noisy environment. Meanwhile it has better performance in hands-free mode in full duplex call.
