Hytera PD755/PD755G

Sturdy DMR handheld radio with display for professional users.

Product description

The PD755/PD755G rounds out the established PD7 series of professional DMR handheld radios from Hytera. In order to provide ideal support in daily work flows, the radio is furnished with an LCD display and a keypad with programmable keys.

User-Friendly Design

The PD755/PD755G impresses with its user-friendly design, excellence balance and wide range of functions.

Improved utilization of the frequency spectrum

Thanks to the TDMA process, the PD755 enables you to configure the available bandwidth with double the number of channels. This has a clear mitigating effect on increasing spectrum scarcity.

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.

Features

Versatile voice calls: Individual call, group call, broadcast call, emergency call
Automatic cell re-selection (roaming) in IP multi-site systems
One-touch functions (incl. text messages, voice calls and supplementary services) scanning (analog, digital or mixed)
Supplementary services, radio check, remote monitor, call alert, radio disable/enable
Vibration function
Emergency calls, Man Down alarm (optional) and lone worker function
Different analog dialing methods: HDC1200, DTMF, 2-tone and 5-tone dialing, squelch method, tone-coded CTCSS/CDCSS
Encryption with 40 bit as per DMRA, or optionally with 128 and 256 bit.
Data services: Text messages, group text messages, control via API
Every radio is available as a GPS variant. Support of GUYS applications, such as AVL and telemetry as well as display of distance and direction of other GPS radios (only PD785G).
Upgradeable software enables the possibility of new features. It is possible to activate other digital and analog operating modes by changing the firmware software.
