Highlights

Ultra-Slim Design

OG308 adopts a lightweight design with only 15mm and 140g. The overall appearance of fashionable simplicity and sleek lines effectively reduces the radio’s heavy feeling and enhances its portability, even if a child can easily operate it.

Hidden Display

OG308 adopts the integrated design of the rest screen, equipped with an LED matrix display to balance the aesthetic. Meanwhile, it can more intuitively show the terminal status, even if the outdoor activities or messy light scenarios can still easily recognize the working status.

AI Noise Reduction

OG308 uses the AI algorithm to recognize and separate the human voice and noise, processing audio signals in real-time and filtering the environment’s noise effectively, to guarantee crystal clear communication in various complicated scenes.

Wide Coverage

OG308 is equipped with high-power RF, which can not only realize the urban calls but also ensure the clear and stable communication effects in various complex environments. No matter in outdoor adventure, construction site operation, or shopping mall dispatching, OG308 always can meet the user’s needs for communication distance and clarity to achieve barrier-free communication.

Channel Copy

Having a farewell with the complicated frequency matching via computer, OG308 can copy another frequency channel within seconds with the channel copy function, which can rapidly organize multi-user communication at the same time under the same frequency.

Emergency Alarm

During emergencies, the emergency alarm of OG308 will send the alerting signal and the locations in time to guarantee personnel safety and make a rapid and coordinated response in critical situations.

Bluetooth Connection

OG308 supports Bluetooth 5.0, which allows you to connect mobile phone APP for frequency adjustments and terminal settings. Bluetooth wireless earphones, headsets, and other peripherals are also used for audio transmission and real-time calls.

VOX

OG308 is designed for situations like driving vehicles, outdoor activities, or hands needed to operate other devices. After turning on VOX, users can still talk with no need to press the PTT button, so users can free their hands and communicate more freely.
