    Hytera HM685 Mobile Radio

Hytera HM685 – Hytera Communications, has recently expanded its DMR mobile two-way radio portfolio by releasing two new models, HM685 and HM655. As part of Hytera’s new generation DMR radio H Series, HM685/655 are designed to provide reliable voice and data connectivity for workers on the road, no matter whether they are drivers delivering packages, technicians maintaining electrical lines, or security patrols across a campus.

The modular and compact design makes HM6 mobiles easy to install, remove and operate in the vehicle. HM685 is equipped with keys and a transflective display, which is readable both in direct sunlight and under poor illumination. HM655 doesn’t have a display or keys on the main unit; instead, it works with a hand-held control head (HHCH), enabling users to easily turn on and off the radio, switch channels and contacts, adjust volumes, and view messages.

The Hytera HM685 mobiles deliver superb audio in noisy environments. The AI-based noise cancellation filters out echoes and background noises such as horn and engine sounds. Their built-in BT 5.0 module not only makes it easy to pair with BT audio accessories, further increasing its versatility, but also facilitates wireless programming. Considering the radio unit may be installed deep in the vehicle compartment, the BT feature is a great effort-saver when the radio needs reconfiguration.

Hytera HM685 is a new generation of entry-level professional DMR mobile two-way radios designed to provide reliable voice and data communications in mobile devices anytime, anywhere. You can stay connected with your teammates wherever the action takes you. The HM6 series is your best partner in transportation, business, utilities, and more.

Compact and lightweight, the HM6 series is easy to install. With the ergonomic design, the four piano-style buttons make operations effortless.

The Hytera HM685 AI-based noise cancellation ensures the HM6 series delivers superb clear audio without ambient noise. With the higher RX sensitivity, the HM6 series provides you smoother communication.

The built-in BT 5.0 module enables you to use various BT audio accessories and program the HM6 series conveniently without the hassle of cables.

Unrivalled Versatility

In addition to reliable voice calls, the Hytera HM685 provides various data services including text message, clarity transmission, emergency alarm, radio disable/enable, GPS Location, and more. These services dramatically enhance your safety and productivity.

Superior Durability

The Hytera HM685 withstands harsh temperatures, shock, and vibration, and meets MIL-STD-810G standards, and IP54 for dust and water intrusion. The connection between the palm microphone and 10 pin aviation connector is a secure fit, while the curly cord has excellent stretching ability to get the maximum service life.

Smooth Communication

Thanks to the high RX sensitivity, the Hytera HM685 can deliver clear and dependable communications even in areas where the signal is unstable or weak.

Digital and Analogue Compatibility

The Hytera HM685 can operate in either analogue or digital mode, which is the ideal solution for you to migrate from analogue to digital with minimal disruption and investment.

Crystal-clear Audio

The Hytera HM685 delivers superb audio in noisy streets or highways. The AI-based noise cancellation filters out echoes and background noises such as horns and engine sounds, making your communication more efficient. The howling suppression prevents the screeching or howling feedback between two radios in the same vehicle, ensuring clear and uninterrupted communication on the move.

Innovative Design

Compact and lightweight, the Hytera HM685 is easy to install, remove, or operate in the vehicle. The front panel of the HM685 adopts two-shot moulding to make the operation area more recognisable. The transflective display is readable even in the dark or direct sunlight. At the bottom of the display, the four piano-style keys offer great haptic feedback when pressed.

Wireless Connection

With the built-in BT 5.0 module, the Hytera HM685 can work with the BT audio accessories to boost your safety and productivity during in-vehicle communications and these radios can be programmed through BT, saving time and resource.
