Setup

Installation Steps:

1. Attach Back Clip Base: Secure the back clip base to the main A20-2X intercom host.
2. Position on Helmet: Identify a suitable location on the side of your helmet, typically near the jawline, where the headset will not obstruct vision or movement.
3. Secure with Clip/Velcro: Insert the back clip base firmly onto the edge of the helmet. For additional security or if the clip is not suitable for your helmet type, use the provided Velcro pads to attach the headset. Ensure it is tightly secured to prevent movement during riding.
4. Install Speakers and Microphone: Place the ultra-thin speakers inside the helmet's ear pockets. Position the microphone in front of your mouth, ensuring it is close enough for clear voice capture but not obstructing your breathing or vision. Connect the speaker/microphone unit to the headset's dedicated port.

Troubleshooting

Device will not power on:

Ensure the battery is charged. Connect the headset to a charger for at least 30 minutes before attempting to power on again. Confirm you are long-pressing the On/Off button for the required duration (3-5 seconds).

Cannot pair with phone:

Ensure the headset is in pairing mode (alternating blue and red indicator light). Make sure Bluetooth is enabled on your phone and it is discoverable. Try restarting both the headset and your phone.

Intercom not connecting:

Ensure both headsets are powered on and within the 1000-meter range. Confirm both are not currently connected to other devices or in other modes. Try initiating the intercom connection again.

Poor audio quality or noise:

Check microphone placement to ensure it is close to your mouth. Verify speakers are correctly positioned in your helmet. Ensure the DSP/CVC noise reduction is active. Move away from sources of strong electromagnetic interference.

Buttons are not intuitive:

Refer to the 'Product Overview' section and the 'Key Function Chart' image for a visual guide to button functions. Practice using the controls while stationary to become familiar with their operation.
