The Hytera HM655 is the next-generation DMR mobile radio for teams that work from vehicles or a base position — delivery fleets, groundskeeping buggies, security patrol vehicles and gatehouse desks. Part of Hytera's H-Series, it replaces the popular discontinued MD655, keeping the slimline body that tucks behind a dash while putting the display and controls on the remote speaker microphone in your hand.

Why choose the Hytera HM655?

Because the control-on-microphone design means the radio itself can be mounted out of sight — everything you need, including an LCD, control buttons and a dedicated emergency button, lives on the speaker mic. With 5–25W of output it reaches much further than any handheld, and AI-based noise cancellation keeps voice clear over engine noise.

Is it compatible with my existing fleet?

Yes — it operates in both DMR digital and analogue modes, so it slots into an existing fleet of Hytera handhelds such as the PD405 or HP605 and can be programmed to your existing channels before dispatch.

HM655 or HM685?

They are twins: the HM655 puts the screen and controls on the speaker microphone; the HM685 has a traditional front-panel display and keys on the radio body. Pick whichever suits how your vehicle is laid out.
