Digital and Analog Compatibility

The HM685 operates in both analog and digital modes, making it an ideal solution for a smooth migration from analog to digital with minimal disruption and investment.

Compact and lightweight, the HM6 Series is easy to install, remove, and operate in vehicles. The front panel features dual-shot molding for improved operability and recognition. The transflective display remains readable in darkness or bright sunlight. Below the screen, the four piano-style buttons provide excellent tactile feedback when pressed.

Wireless Connectivity

Crystal-Clear Audio

The HM685 delivers outstanding audio clarity on busy streets and highways. AI-based noise cancellation filters echoes and background noises such as horns and engine sounds, ensuring you can hear and be heard clearly. Noise suppression also prevents feedback or howling effects between radios in the same vehicle, enabling uninterrupted communication on the move.

Unmatched Versatility

In addition to reliable voice calls, the radio supports a wide range of data services, including text messaging, voice recording, emergency alarms, radio enable/disable, GPS positioning, and more—significantly enhancing safety and productivity.

Superior Durability

The HM685 withstands extreme temperatures, shocks, and vibrations, and complies with MIL-STD-810G and IP54 standards for dust and water protection. The connection between the palm microphone and the 10-pin aviation connector remains secure and resistant to loosening. The microphone cable offers excellent stretch resistance, protecting the microphone and ensuring maximum service life.
