Various installation options

With its operation via handheld microphone, the MD655/MD655G can be installed anywhere within a vehicle. Thanks to Hytera's wide selection of cable lengths, this mobile radio can be placed in whichever location is optimal for you.

Adaptable transmitting power

Programming the MD655/MD655G allows transmitting power to be increased from 1 W up to 25 W.

Analogue and digital mobile radio (dual mode)

With the MD655/MD655G, it's possible to confi­gure both analogue and digital channels. This enables quick and easy movement between analogue and digital modes.

Improved utilization of the frequency spectrum

Thanks to Hytera Pseudo Trunking and the TDMA procedure, the MD655/MD655G allows the available bandwidth to be assigned to twice the number of channels. This has a clear mitigating effect on increasing spectrum scarcity.

Expansion interface

Thanks to the expansion interface, the range of functions powered by the MD655/MD655G can be increased. Accessories and applications, developed by partners, can also be connected to this interface.

Hytera RD985S

The Hytera RD985S is an impressive digital systems repeater. Supporting conventional analogue and digital modes, it can also be used in DMR trunked radio systems (Tier III), and with up to 50W power is responsible for delivering excellent coverage in DMR simulcast and Hytera XPT systems. The RD985S repeater supports not only conventional analogue and digital modes, but also other modes that can be unlocked with a chargeable licence. It can be upgraded into a base station for DMR simulcast, DMR trunked radio (Tier III) or Hytera XPT radio systems. This means that the RD985S is a secure investment for growing radio projects


Allows the monitoring and control of external devices, either by another radio or via a software application.

Emergency Mode

Raise an alarm with top priority to a base station or to other radios with the pre-programmed emergency mode, identifying the ID of the person issuing the alarm.

Lone Worker

The Lone Worker feature uses a timer in the radio to measure inactivity. If the timer expires, a warning is issued, and if there is no response to that, the alarm is triggered.

Pseudo Trunking 

Using pseudo-trunking, a Hytera patented technology, slots can be shared to improve capacity usage with transmissions either direct to handset or to repeater.


Hytera XPT (Extended Pseudo Trunking) enables you to use limited spectrum resources more efficiently, dynamically assigning channel resource without needing a dedicated control channel.


G version only (via seperate antenna), Global Positioning System, enabling location based services to improve safety and control.

Intelligent Audio

Combining noise cancelling technology to remove nuisance noise from the transmission, with powerful speakers to deliver clear communications.

Bluetooth Audio

Optional (external adapter accessory), wireless connectivity to audio devices to improve user experience.
