Product description

The handheld radio PD685 ideal companion for the move to digital radio. As a member of Hytera's PD6 series, the PD685 offers a lightweight metal housing and supports both digital and analog radio. Thanks to its full keypad, three programmable keys and its bright LCD display, the PD685 can be operated easily and without complications.

 

Features

Analog + digital mode

Supports both digital and analog modes and is compatible with common analog systems.

Slim design

Metal frame, slim body (plus battery is only 310g).

Multi-channel,multi-zone

Up to 1024 channels and 64 zones to meet the broad and flexible communication needs of business users.

Stable and reliable

Matte texture, plastic body, pressure and wear resistance, quality meets MIL-STD C/D/E/F/G, waterproof and dustproof IP67, accidentally dropped or drenched, can also be used

Voice encryption

Provides basic voice encryption and scrambling to protect business users

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.

Noise reduction

Clear voice is also available in noisy environments with narrowband speech codec and digital error correction.
