      Small, lightweight and narrow

      The radios of the PD6 series are only 27 mm deep, making them particularly compact. The housings are trimmed in a high-quality aluminum frame and are comfortable to carry for long periods with a weight of only 310 g (PD685).

      Long battery service life

      With the supplied 1500 mAh lithium-ion battery, the handheld radio PD685 has an operating period of at least 16 hours in digital mode. With the optionally available 2000-mAh battery, it will even be 20 hours.

      Improved utilization of the frequency spectrum

      The PD685 can be operated in TDMA direct mode and pseudo trunking. This assignment of the available bandwidth with double the number of channels leads to a significant easing of the increasing shortage of frequencies in the operation of DMR mobile radio systems compared to analog mobile radio systems.

      Expanded frequency range

      The frequency range in UHF stretches from 400 MHz to 527 MHz.

      Versatile

      The PD685 possess both an analog mode and a digital mode and is compatible with analog radio systems; as a consequence it is very easy for you to change to the digital age. Along with conventional DMR (DMR Tier II, the PD685 also support DMR trunked radio. In addition, it can be used in Hytera XPT and simulcast systems.

      Features

      • Every radio of the PD6 series is also available with GPS. Variants with GPS support GIS applications, such as AVL and telemetry.
      • Encryption with the encryption algorithm ARC4 (40 bit) in accordance with DMRA or with optional algorithms AES128 and AES256 (128 and 256 bit)
      • Expansion interface for applications
      • Man-down function (optional)
      • Leasing function
      • Versatile voice calls: Individual call, group call, broadcast call, emergency call
