Hytera Atex digital radio

Hytera PD79X*Ex, fully compliant to DMR open standard of ETSI, comes to be the world's First IIC Atex Digital Portable Radio.  FM-2010 standard of North America, IEC, and ATEX standards compliance, plastic-encapsulated technology,  error-prevention design, and IP67 protection ensure intrinsically safe and reliable communication in hazardous scenes with explosive gas and combustible dusts.
Ergonomic Design
PD795 Ex adopts a 1.8-inch high resolution color transflective LCD display, allowing crystal-clear visibility even under outdoor strong light.
Big keypad ensures precise and convenient operation even with gloves on.
Durability 
Strictly compliant with FM -2010 standard of North America, IEC & ATEX standards, PD795 Ex passes one-month series tests in simulated harsh environments. MIL-STD-810C/D/E/F compliance and & IP67 protection  ensure outstanding and reliable performance in demanding  environments.
Error-prevention Design
Automatic alarm will be triggered when batteries or accessories of lower security level are applied, thus avoiding accidents of this kind.
Plastic-encapsulated technology
The plastic-encapsulated technology is applied to the radio unit and battery, isolating their internal circuits from dangerous gas and dusts outside. This technology is applied in PD795 Ex at the cost of lower production efficiency due to the challenging demands in design and manufacturing, which is always worthy as Hytera sees it.
IP67 Protection 
One-meter submersion up to 30 minutes
Anti-static shell
The rugged and durable shell dissipate static electricity, thus preventing  sparks..
High-strength LCD protective len
The high-strength LCD protective len minimizes scratch and withstands the impact of 1KG hammer.
Innovative battery latch
The patented battery latch design keeps the battery in place when  the radio falls from a height.
Non-slip design
The non-slip design delivers strong grab-hold, also  comfortable operation.. 

Key Features:

GPS
The built-in GPS module supports GPS data transmission.
Dual-mode (Analog & Digital)
PD79X* Ex operates in either analog or digital mode,  It is compatible with the current analog system, ensuring a smooth analog-to-digital migration.
Versatile Voice Calls 
The DMR intelligent signaling supports various voice calls, including Private Call, Group Call and All Call.
Vibration
This feature is helpful in alerting you to reception of any voice call or message under noisy conditions
IP Service
PD79X* Ex allows multiple IP functions when connected with a PC via IP address.
Various Analog Signaling
