03. Installation Instructions

Mounting the Clamp Mount Bracket

Step 1: Gently spread the clamp mount bracket and slide it between the helmet shell and the inner padding. Secure the bracket by pressing it firmly into place. (Refer to diagram)

Step 2: For helmets where the clamp mount is not suitable or preferred, use the 3M adhesive mount bracket. Peel off the 3M adhesive tape. Attach the bracket firmly to the left side of the helmet and press down for 15 seconds. For best adhesion, allow 24 hours before use. (Refer to diagram)

Note: While a 3M adhesive mount bracket is provided, LEXIN recommends using the clamp mount bracket. LEXIN is not responsible for any damages resulting from the use of the 3M adhesive mount bracket.

Attaching the Intercom Unit

The back of the G2P unit has two rectangular posts. The mounting bracket has corresponding rectangular slots. Align the posts on the intercom unit with the slots on the bracket. Slide the unit downwards firmly until it clicks into place. (Refer to diagram)

Removing the G2P Unit

Before removing the G2P unit, ensure it is disconnected from the speakers. Push the intercom unit upwards and to the left to detach it. (Refer to diagram)

Installing the Speakers

Note: For optimal FM radio reception, install the speaker with the shorter wire on the left ear and the speaker with the longer wire on the right ear. Position the speakers inside the helmet.

Step 1: Attach the Velcro pads to the inside of the helmet where the speakers will be placed.

Step 2: Securely attach the speakers to the Velcro pads. If the helmet's ear pockets are deep, use the provided speaker pads to bring the speakers closer to your ears.

Step 3: Tuck the speaker wires neatly inside the helmet shell and padding.

Note: Speaker pads are included. Use them to adjust speaker positioning if the helmet's ear pockets are deep, ensuring the speakers are close to your ears.

Installing the Microphone

Note: Use the wireless microphone for full-face helmets and the boom microphone for open-face helmets. Choose the microphone that best suits your preference and helmet type.

Full-Face Helmet / Wireless Microphone Installation

Step 1: Find a suitable position on the center of the helmet. Attach the Velcro pad for the microphone at this location.

Step 2: Attach the wireless microphone to the Velcro.

Step 3: Connect the microphone to the speaker on the left side. (Refer to diagram)

Open-Face Helmet / Boom Microphone Installation

Step 1: Place the Velcro pad on the left side of the helmet. Position the boom microphone onto the Velcro.

Step 2: Adjust the microphone so that the white triangular mark faces your mouth. (Refer to diagram)

Replacing the Faceplate

Step 1: Remove the original faceplate. Locate a small gap on the left side of the faceplate. Use a thin object to gently pry the faceplate off the G2P unit.

Step 2: Select the new faceplate. Align it with the intercom unit and press firmly until it snaps into place.
