Improved utilization of the frequency spectrum
Thanks to the TDMA process, the PD705/PD705G enables you to configure the available bandwidth with double the number of channels. This has a clear mitigating effect on increasing spectrum scarcity.
Robust and reliable handheld radios that can demonstrate their outstanding performance capability in tough environments too.
With its compact case, degree of protection IP67, outstanding voice quality and support of digital and analogue radio, the PD705/PD705G provides your radio communication with a fresh wind. The handheld radios PD705 and PD705G (variant with GPS) are designed in accordance with the DMR standard.

Hytera's PD705 and PD705G (variant with GPS) handheld radios offer ease of operation and reliability, which is indispensable in critical situations. The ingeniously devised and intelligent industry antenna design assures comfortable operation and remarkable GPS properties.
The two rotary buttons of the radio transceiver are separated by the antenna. This design prevents incorrect operations.
The PD705/PD705G meets all the requirements of the open ETSI standard DMR as well as MIL810-C/D/E/F/G and degree of protection IP67. The device series thus offers excellent features even under harsh operating conditions.
Compared to analog technology and the FDMA process, TDMA enables the battery service life to be increased by about 40% depending on operating conditions.
With the combined application of the narrow band codex and technologies for debugging the PD705/705G ensures an excellent voice quality even in loud environment and in peripheral areas of radio coverage.
Upgradeable software enables the possibility of new features. By altering the firmware-software, other digital and analog operating modes can be enabled, without the need for purchasing a new radio device.
