Installation

Lexin FT4 Pro to a Helmet

With Screws

• Mount the bracket between the internal padding and the external shell of the helmet.
• Tighten the two screws between the bracket and clamp plate by using the included Allen wrench.

Note: Depending on the size and shape of your helmet, you may need to change the thickness of the rubber pad between the clamp plates. You can find two extra rubber pads in the box. To increase the overall thickness, attach the thinner pad to the original rubber pad or replace the original rubber pad with the thicker one.

With Adhesive Pad

• If you have any problems with the mounting bracket you may want to use the 3Mtapet to attach it to the helmet.

• Take off the rubber pad fromthe bracket, and peel off the protective backing sheet of the double-sided 3Mtape.

• The white side adheres to the bracket and the red side adheres to the helmet.

• To install, press and hold for 15 seconds and allow the glue to dry for 24 hours.
  Note: Even though the 3MTape mounting is provided for convenience, LEXIN recommends using the mounting bracket.

• The 3M Tape is of interest as an option that you may use at your own risk. LEXIN does not assume any responsibility for use of it. Installing Microphone:
  Note: The button microphone and boom microphone can be interchanged between a full-face or open-face helmet.

• Choosing between the two is based on your preference and what fits best in the helmet(s).

Full Face Helmet/Button Microphone.
Step 1: Locate an area in the nose section just to the left of the center to mount and adhere one-half of the Velcro pad.
Step 2: Adhere Velcro pad to the button microphone, then attach it to the pad in a helmet.
Step 3: Connect the microphone jack headset connector.

Open Face Helmet/BoomMicrophone
Step 1: Adhere one half of the Velcropadtothe base of the microphone and the other half to the inside of the helmet under the padding.
Step 2 : Adjust the direction of the microphone so that the triangular markonthemicrophone is pointing toward your mouth.
Step 3: Use the boom microphone holder for additional support to the microphone if necessary.

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.
Step 1: Place the speakers into the helmet’s inner padding.
Step 2: Push the speakers and microphones firmly against the Velcro pads. If the helmet has deep ear pockets, you can use the provided spacers to place the speakers closer.
Step 3: Press the wires between the helmet liner and shell. Mounting the Lexin FT4 Pro Unit to Bracket: Mount the Lexin FT4 Pro main unit on the bracket. Insert the device into the top clip, then press in the bottom until it clicks into place.
To remove the main unit from the bracket, press the top part of the bracket and take it out. Please kindly read the manual carefully and pay attention to the following details.

IMPORTANT
The Audio Jack plug for the LEXIN intercom is different from most other headset plugs to ensure that it is waterproof, and requires more force to insert into the jack to ensure clear sound& waterproofing. This is illustrated in the image above.

IMPORTANT
Speaker placement is very important. To ensure the best placement, remove the padding and test with music once installed. Please adjust the direction of the microphone so that the triangular mark on the microphone is pointing toward your mouth.
