Mounting Instructions

Installation of Mounting Bracket

1. With Clamp Mount: Insert the clamp mount between the helmet shell and padding, and push the clamp mount in completely to mount the unit. (Illustrated on the right).

[Diagram: Shows a helmet with the clamp bracket being attached. An 'Aufspannen' (Tighten) label is present.]

2. With 3M Adhesive Mount: Alternatively, use the 3M adhesive mount. Peel off the protective film from the double-sided 3M tape and attach the mount to the appropriate position on the left side of the helmet. Hold for 15 seconds and let the adhesive cure for 24 hours. (Illustrated on the left).

[Diagram: Shows the 3M mount being attached to a helmet.]

Installation of G2 Main Unit

There are two raised square columns on the back of the G2 Main Unit. The bracket has corresponding square holes. Align the square columns on the back with the square holes of the bracket and slide the main unit in. Slide the G2 Main Unit into the bracket until the columns on the main unit are fully secured in the bracket's holes. (Illustrated on the right).

[Diagram: Shows the G2 unit being attached to the bracket, with arrows indicating the sliding motion.]

Removal of Main Unit

Before removing the G2 Main Unit from the bracket, ensure the headphones are not connected to the main unit. Slide the G2 Main Unit firmly towards the upper left corner until the unit is detached from the bracket. (Illustrated below).

[Diagram: Shows two helmet views with arrows indicating the removal direction.]

Installation of Headphones

Note: The speaker with the shorter cable is for the left ear, and the speaker with the longer cable is for the right ear. Place the speakers into the inner padding of the helmet. If the helmet has deep speaker positions, you can use the included earphone pads to position the speakers closer to your ears for better sound quality.

[Diagram: Shows a speaker with an earphone pad.]

1. Peel off the rough surface of the speaker's Velcro and attach it to the helmet's inner lining.
2. Place the speakers into the inner padding of the helmet. If the helmet has deep ear pockets, you can use the included earphone pads to position the speakers closer to your ears for better sound quality.
3. Hide the excess headphone cable between the helmet padding and the shell.

[Diagram: Shows a helmet interior with headphone cable being tucked away.]

Installation of Microphone

Note: The gooseneck microphone and the button microphone can be interchanged between integral helmets or open-face helmets. The choice between the two depends on your preference and the most suitable microphone for your helmet.

Integral Helmet/Button Microphone

1. Find an area in the middle of the chin area of the helmet to attach the rough surface of the microphone's Velcro.
2. Attach the button microphone to the adhered Velcro.
3. Connect the microphone to the headphone on the left side. (Illustrated on the right).

[Diagram: Shows a helmet chin area with a button microphone attached.]

Open Helmet/Gooseneck Microphone

1. Attach the rough surface of the microphone's Velcro to the left inner side of the helmet. Attach the gooseneck microphone to it.
2. Adjust the direction of the microphone so that the triangular marking on the microphone points towards your mouth.
3. If necessary, use a microphone holder to secure the microphone. (Illustrated on the right).

[Diagram: Shows a helmet interior with a gooseneck microphone attached and adjusted.]

Changing the Shell

1. Remove the old shell from the main unit (there is a small gap on the left side of the shell; use a thin object to pry the shell off the main unit).
2. Select a new shell, align it with the main unit, and press the shell down firmly until it fits perfectly.

[Diagram: Shows the shell being pried off and then attached to the G2 unit.]

While holding the Volume - button for 7 seconds, the G2 device will also announce "Pairing". Do not release your finger until you hear the voice prompt about the battery status.

The battery level is divided into the following stages: 100%, 80%, 50%, 25%, LOW.

Note: When the battery level is below 30%, a "Battery Low" voice prompt will sound every 15 minutes. The device will continue to operate for another 1 to 1.5 hours. It will then automatically shut down.

Pairing Devices

Pairing with Mobile Phone

Note: A G2 can maintain simultaneous connections with up to two devices (e.g., one mobile phone and one Bluetooth device). Upon next power-on, the LEXIN G2 Bluetooth will automatically connect to the last connected device, provided the device's Bluetooth is turned on or it is in standby mode for connection.

1. While the device is off, press and hold the Power button for approximately 5 seconds until the LED blinks red and blue alternately. The LEXIN G2 will announce "Pairing". The device is now in Bluetooth pairing mode.

3. Bluetooth Stereo Music / FM Radio / Navigation Announcements

Note: A function with lower priority will always be interrupted by a function with higher priority. For example, stereo music will be interrupted by an intercom call, and an intercom call will be interrupted by an incoming mobile phone call.

Pairing with Other LEXIN Models (Example: G2 with B4FM)

The connection steps between a G2 and a LEXIN product of another model (e.g., LEXIN B4FM / LEXIN G16 / LEXIN MTX / LEXIN GTX / LEXIN NOVUS X2, etc.) are the same. Below is an example of connecting a G2 and a B4FM.

In standby mode, press and hold the Intercom button of the G2 and B4FM for 2 seconds. The G2's LED will blink red and blue rapidly. The voice prompt "Pairing" will be announced.

[Diagram: Shows G2 and B4FM units, with "Koppeln" (Pairing) indicator.]

• Hold the Intercom button for 2 seconds until the LED blinks red and blue alternately. (For G2)

6-Way Bluetooth Pairing

The LEXIN G2 supports Bluetooth pairing in a group (2 to 6 participants) and 2-way communication. This means a G2 device can establish Bluetooth connections with up to 5 other G2 devices simultaneously, enabling 2-way communication after successful pairing.

To avoid confusion between main units, we recommend marking the device name of each G2 Main Unit before pairing, e.g., Device 1 to Device 6 as referred to in the following operating manual.

Pairing Channels and Device Matrix

The table below shows the Intercom channel settings (A, B, C, D, E) for pairing between devices. Each G2 device needs to connect with 5 other G2 devices for a 6-way connection.

In the table, A, B, C, D, and E represent the five Intercom channel settings. Please refer to the simple summary description below for the connection steps. Once all devices are paired, they will all be connected to each other.

Other Considerations

Bluetooth Connection in a Group

The devices are connected in a chain. To maximize communication range, please keep the devices in the order of connection.

The device cannot be connected to a Bluetooth device (phone or GPS) when it is serving as a communication device.

Activating Intercom Call

It may take a few seconds for a connection to be established with other devices. Please wait until the devices have established a connection before you start speaking.

Distance Between Devices

During an intercom call, there may be a mute, and eventually, the call will be disconnected if a rider is out of range. In this case, the LEXIN G2 will automatically attempt to re-establish the connection with that device every few seconds.

Save Battery

To save battery power, disconnect the intercom connection when you do not need to use the intercom function.
