Setup and Installation
Charging the Headset
Before first use, fully charge the headset. Connect the provided Micro-USB charging cable to the headset's charging port and the other end to a USB power source (e.g., computer USB port, USB wall adapter). A full charge typically takes approximately 2 hours. The charging indicator light will change to indicate a full charge.
Installing in Helmet
The H4 headset is designed for easy installation using detachable velcro, ensuring a firm fit within various helmet types. It is compatible with most open-face, modular, and full-face helmets. For full-face helmets, ensure sufficient space in the chin area for optimal microphone placement.
- Identify suitable locations inside your helmet for the speakers, typically near your ears.
- Attach the velcro pads (if not already attached) to the back of the speakers and inside the helmet.
- Securely place the speakers inside the helmet.
- Position the microphone boom arm so that the microphone is close to your mouth for clear audio transmission.
- Route the cables neatly within the helmet padding to avoid interference or discomfort.
