Handy Talky Hytera PD408 Dual System Mode (System Digital & System Analog)
Hytera PD408 Great voice quality
With its embedded digital technology Hytera PD408 produces outstanding voice quality even in noisy environments and at the outer perimeter of radio coverage.
Hytera PD408 Better usage of the frequency range
Thanks to the TDMA method, Hytera PD408 makes it possible to configure the available bandwidth with double the channel capacity of conventional analog radio. This has a clear mitigating effect on increasing spectrum scarcity.
Hytera PD408 Mixed analog and digital channel
This function ensures that Hytera PD408 can detect analog and digital signals and change automatically to the relevant operating mode.
Robust
Hytera PD408 handheld radio is dust and water-resistant according to IP55, and meets the US military standard MIL-STD-810 C/D/E/F/G.
Hytera PD408 Long battery service life
With a battery service life of up to 16 hours in digital operation, the PD405 is enduring and is thus reliable even when deployed for long periods.
