Description
This new generation entry-level professional DMR mobile two-way radio is designed to provide reliable voice and data communication in both vehicles and desktop installations. Compact and lightweight, the radio is easy to install. With the ergonomic design, the four piano-style buttons make operations effortless. The AI-based noise cancellation ensures the radio delivers superb clear audio without ambient noise. The radio is born to be your best partner in transportation, business, utilities, and more.
RELIABLE 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.
INNOVATIVE DESIGN
Compact and lightweight, the Hytera HM685 is easy to install, remove, or operate in the vehicle. The front panel adopts two-shot molding to make the operation more recognizable. 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 HM685 can work with the Bluetooth audio accessories to boost your safety and productivity during in-vehicle communications. And these radios can be programmed through Bluetooth, saving time and resource.
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 horn and engine sounds, making you hear and be heard in the conversation. The howling suppression prevents the screeching or howling feedback between two radios in the same vehicle, ensuring clear and uninterrupted communication on the move.
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 the 10-pin aviation connector is very secure preventing it from becoming loose. The palm microphone cord has excellent stretching ability to protect it thus giving the maximum service life.
