Nível Máximo de Segurança
Com a aprovação "ia", o PT790 Ex pode ser usado em áreas onde há uma atmosfera explosiva contendo uma mistura de ar e gases combustíveis permanentes, vapores ou névoas (Zona 0).
Robusto e Confiável
À prova de poeira e impermeável (IP67), resistente à imersão em 1 metro de água doce por um período de até 30 minutos, o PT790 Ex atende aos requisitos para operar nas condições mais adversas
Proteção do usuário
Com GPS integrado, o PT790 Ex melhora a segurança do usuário com recursos como o alarme de emergência
O PT796 Ex oferece acesso rápido à rede de rádio TETRA, seus serviços e infraestrutura no modo troncalizado (TMO) ou, alternativamente, a comunicação entre rádios no modo direto (DMO).
Serviços de voz e dados
Uma variedade de opções de voz e serviços de dados / mensagens oferecem funcionalidade e segurança excepcionais, de acordo com o padrão TETRA
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
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.
The built-in GNSS module supports GPS, GLONASS, Beidou. Its tracking sensitivity is up to -164dBm, and its accuracy is within 2 meters.
When a user falls down, the radio can automatically alert others.
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.
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.
