    User-Friendly Design

    From the PD705, with its impressive, durable chassis, through the PD785 with its large color display and full keyboard: This series stands out thanks to its user-friendly design, its finely balanced features and its extensive range of functions.

    Improved utilization of the frequency spectrum

    The PD7 series can be used in TDMA direct mode and in pseudo-trunking mode. 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.

    Versatile - supports digital and analog operating modes

    The radios in the PD7 series possess both an analog mode and a digital mode and are 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 radios also support analog trunked radio as per MPT1327 and DMR trunked radio. In addition, they can be used in Hytera XPT and simulcast systems.

    Quality and versatility

    With outstanding voice quality and various applications, this family of DMR handheld radios is a breath of fresh air for your communication.
