Installation Instructions

Installing Bracket for GTX to Helmet

Clamp Installation: Open the clamp and insert it into the helmet wall. (As shown in the diagram).

3M Tape Mounting Bracket Installation: Tear off the protective paper on the back of the 3M tape, then stick the 3M mounting bracket to a suitable position on the left side of the helmet. Press for 15 seconds to allow the glue to cure for 24 hours. (As shown in the diagram).

Note: LEXIN recommends using the bracket mounting. The 3M Tape bracket is an option for convenience, but use is at your own risk. LEXIN assumes no responsibility for its use.

Mounting the GTX Unit

Align the square column on the back of the main unit with the square hole of the base. Slide the main unit down onto the bracket until it clicks firmly into the bottom portion of the bracket. (As shown in the diagram).

Diagram: A diagram showing the GTX main unit being aligned with and slid onto the mounted bracket until it clicks into place.

Remove The GTX Unit

To remove the main unit from the helmet, ensure the headset is not connected to the main unit, then remove the main unit and the mounting bracket together. (As shown in the diagram).

Diagram: A diagram showing the GTX unit being detached from the helmet bracket, with a "Press" indicator on the release mechanism.

Installing Speakers

Note: The speaker with the shorter wire is for the left ear, and the speaker with the longer wire is for the right ear. This configuration also enhances FM radio reception.

Step 1: Peel off the speaker 3M tape and stick it into the helmet's inner padding.

Step 2: Push the speakers firmly against the velcro pads. If the helmet has deep ear pockets, use the provided spacers to position the speakers closer to your ears.

Step 3: Hide the wires between the helmet liner and shell. (As shown in the diagram).

Diagram: A diagram showing speakers being placed inside a helmet, with wires being tucked between the helmet liner and shell.

Installing Microphone

Note: The button microphone and boom microphone are interchangeable between full-face and open-face helmets. Choose based on your preference and helmet fit.

Full-face Helmet/Button Microphone

Step 1: Locate an area in the center of the mouth section of the helmet to install and adhere half of the microphone velcro pad.

Step 2: Attach the button microphone to the attached velcro.

Step 3: Connect it to the headphone connector from the left.
