      Durability

      The PD795 Ex handheld radio complies with all the requirements of the European ATEX directives, IEC guidelines and the North American FM standard. Furthermore, the device meets the MIL-STD-810C/D/E/F/G standard and is dustproof and waterproof in accordance with the IP67 protection class. This makes the PD795 Ex ideal for safe and reliable operation even in potentially explosive areas.

      ATEX certification

      All radios used in potentially explosive areas must comply with the European Union's ATEX directives.

      The PD795 Ex meets the following ATEX directives:

      • ATEX Gas Protection: II 2 G Ex ib IIC T4
      • ATEX Dust Protection: II 2 D Ex ib IIIC T120 °C
      • ATEX Protection for Mining Application: I M2 Ex ib

      Fail-safe design

      Using batteries or accessory components with an insufficient level of protection automatically triggers an alarm so that malfunctions of this type cannot occur.

      Plastic encapsulation

      Both the radio itself and the battery are encapsulated in silicone in order to connect the internal circuits and to prevent the penetration of liquids, dust and harmful gases.

      High-strength LCD protective cover

      The high-strength LCD protective cover is extremely scratch-resistant and would even withstand being struck by a 1-kg hammer.

      Innovative battery latch

      The patented lock of the battery ensures that the battery cannot fall out if the radio should be dropped onto a hard surface.

      Integrated GPS as standard

      Using the integrated GPS module, the PD795 Ex can send location information to dispatcher systems. Dispatchers can evaluate this information and use functions such as geofencing, radio localization and GPS tracking.

      Upgradeable firmware

      Having upgradeable firmware makes it possible to enhance the system with new features. Changing the firmware-software enables other digital and analog operating modes to be integrated without having to purchase a new radio.

      Over the Air Encryption

      The over-the-air encryption function encrypts the signaling on the air interface. All subscribers need the relevant access rights to take part in the radio communication. This means that call setup is encrypted, the system is protected against unauthorized access and connection data cannot be tapped.

      Features

      • Supports different operating modes; optional analog or digital operation
      • Versatile voice calls: Individual call, group call, broadcast call, emergency call
      • GPS functions (retrieving and sending location data)
      • Data services (text messages, group text messages, control of the radio via API)
      • Various analog dialing methods (HDC1200, DTMF, 2-tone and 5-tone dialing, squelch procedure / CTCSS/CDCSS tone call)
      • Supplementary services, radio check, remote monitor, call alert, radio disable/enable
      • Menu available in different languages
      • One-touch functions (incl. text messages, voice calls and supplementary services)
      • Scanning
      • Automatic cell re-selection (roaming) in IP multi-site systems
      • Secure encryption with encryption algorithm ARC4 (40 bit) in accordance with DMRA or with optional algorithms AES128 and AES256 (128 and 256 bit)
      • Over the Air Encryption
