Hytera PD685 - Robust Long Range Two Way Radio

About the Hytera PD685

The PD6 Series from Hytera offers a sleek, innovative Two Way Radio for professional users. With a lightweight, crafted Metal Design, supporting both Digital and Analogue Technology, the PD6 Series is a popular feature rich device.

The PD6 Series of radios from Hytera are only 27mm deep, making them particularly thin. The Chassis is encased in a high quality Aluminum Metal Frame and weighs only 310g, these Handsets are ideal for long operations as they are easy to carry.

With the 1500 mAh Standard Lithium-ion Battery, the PD6 Series of Radios can achieve an operating time in Digital Mode of at least 16 hours. With the optionally available 2000-mAh battery, this could be up to 20 hours. The PD6 series can be operated in Pseudo-Trunk 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 Analogue Mobile Radio Systems.

The frequency range in UHF is 400 MHz to 527 MHz.

The PD6 series was developed in compliance with the ETSI DMR standard. Digital Mobile Radio (DMR). The handheld radios support the conventional DMR operation and can also be used in analogue mode. This makes the terminals of the PD6 series the ideal companion for the migration to Digital Mobile Radio.

In addition to conventional DMR (DMR Tier II) and Analogue Modes, all PD6 radios support operation in DMR trunked (Tier III), XPT digital trunking and MPT 1327.

• Every Radio of the PD6 Series is also available with GPS (Denoted by the Model Number followed by a ‘G’). Variants with GPS support GIS Applications such as
• AVL, Telemetry and also Include a Man Down Function
• 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
• Priority Interrupt
• Leasing Function
• Versatile Voice Calls - Individual Call, Group Call, Broadcast Call, Emergency Call
• Bluetooth Accessories Available with Optional Adapter
• Roaming

This Radio requires a license to operate - If you do not already have an existing Radio Licence then one will need to be purchased before using the Radio -
