4.1 Charging the Device

Before first use, fully charge the GX4 headset. Connect the provided USB charging cable to the charging port on the headset and to a USB power source (e.g., computer, wall adapter). The charging indicator light will show charging status and turn off when fully charged. A full charge takes approximately 1.5 hours.

4.2 Mounting the Headset

The GX4 can be mounted to most helmets using either the clip-on bracket or the adhesive bracket.
