Operating Instructions
The ASMAX S1 offers a range of features for enhanced communication and entertainment. Familiarize yourself with its functions for a smooth riding experience.
Power On/Off
Refer to the device's physical buttons for power control. Typically, a long press on the main button will power the unit on or off.
Pairing and Connectivity
The S1 utilizes advanced Bluetooth 5.4 technology for stable and efficient connections.

- Universal Pairing: The S1 supports universal Bluetooth protocol connectivity, allowing it to connect not only to other ASMAX models but also to other brands of intercoms, cell phones, and various Bluetooth devices.
- Phone Pairing: To pair with your smartphone, activate Bluetooth on your phone and search for 'ASMAX S1'. Select it to connect.
Voice Control (AI Human-Machine Interaction)
The ASMAX S1 features AI voice control for hands-free operation, enhancing safety and convenience.

- Activation: Simply say "Hi Max" to activate the voice assistant.
- Online Voice Control: When connected to the ASMAX app and the internet, you can use smart voice interaction for operations like navigation, messaging, and calls.
- Offline Voice Control: The S1 can also perform local offline voice commands for basic functions without an internet connection.
- Commands include: "Radio On", "Phone Pairing", "Free Mode", "Group Mesh", "Battery Status", "Music On", and more.
Intercom Modes (Mesh Group Intercom)
The S1 supports up to 8 riders in mesh intercom mode, offering flexible communication options.

- Free Mode: Ideal for open channels within Bluetooth range, allowing quick and easy communication among riders.
- Group Mode: For private conversations, supporting up to 8 riders. This mode allows for a team leader chat (2-3 people) and private one-on-one calls.
- Range: The overall range from the first to the last rider can be up to 8 km (5 miles), with a unit-to-unit range of up to 3 km (1.8 miles). Note that obstacles can affect communication range.
Audio Multitasking
The S1's dual-chip octa-core processor allows for audio multitasking, enabling you to enjoy multiple audio sources simultaneously.

You can listen to music, FM radio, or navigation instructions while participating in a group intercom conversation.
FM Radio
The built-in FM radio allows you to listen to your favorite stations without needing a complex setup or internet connection.
- Frequency Range: Wide FM radio reception frequency of 76-108 MHz.
- Features: Automatic search of frequency bands and the ability to preset up to 6 stations.
Intelligent ENC Noise Cancellation
The S1 is equipped with Intelligent Environmental Noise Cancellation (ENC) to ensure crystal clear communication.

Even at speeds up to 120 km/h, the system intelligently filters out wind and road noise, restoring the pure human voice for effective communication.
Charging
The S1 features a long-lasting 980mAh battery and supports 60-minute fast charging via its Type-C interface. A full charge provides up to 13 hours of continuous communication and music playback.
Maintenance
- Cleaning: Use a soft, damp cloth to clean the exterior of the S1 main unit. Avoid using harsh chemicals or abrasive materials.
- Water Resistance: The S1 is IPX7 waterproof, meaning it can withstand immersion in water up to 1 meter for 30 minutes. However, it is recommended to avoid prolonged exposure to heavy rain or submersion to ensure longevity.
- Software Updates: Keep your unit up-to-date by using the ASMAX Connect App. You can download and install the latest software directly to your S1 without needing cables.
- Storage: When not in use for extended periods, store the S1 in a cool, dry place. Ensure the battery is partially charged (around 50%) before storage to maintain battery health.
Troubleshooting
- No Power: Ensure the battery is charged. Connect the S1 to the Type-C charging cable and a power source. If it still doesn't power on, try a different charging cable or adapter.
- Cannot Pair with Phone/Intercom: Ensure both devices are in pairing mode and within range. Turn off and on the S1 and try pairing again. For universal pairing, ensure the other intercom is also in its pairing mode.
- Audio Quality Issues (e.g., audio lost at high speed, cut conversations): Verify that the speakers and microphone are correctly positioned inside the helmet. The S1 features ENC noise cancellation, but extreme wind noise or exceeding the recommended working speed (160km/h) can affect clarity. Ensure you are within the optimal intercom range (3km unit-to-unit).
- Voice Control Not Responding: Ensure the microphone is not obstructed and is positioned correctly. Speak clearly and at a normal volume. Check if the "Hi Max" activation phrase is being recognized.
- FM Radio Not Working: Check for strong FM signals in your area. Try auto-searching for stations again.
- Device Freezes/Unresponsive: Perform a soft reset by holding down the main power button for an extended period (e.g., 10-15 seconds) until the device restarts.
User Tips
- Optimal Intercom Range: While the S1 boasts a significant range, for the clearest communication, especially at higher speeds, try to maintain a reasonable distance from other riders. Obstacles like buildings or dense terrain can reduce effective range.
- Universal Compatibility: The S1's universal pairing feature means you can connect with various brands of intercoms. If you encounter issues, ensure the other device is in its specific pairing mode for third-party connections.
- Voice Command Efficiency: Practice using the "Hi Max" command in a quiet environment first to get accustomed to its responsiveness. This will help you use it effectively while riding.
- Regular Software Updates: Utilize the ASMAX Connect App to regularly check for and install firmware updates. These updates often include performance improvements, bug fixes, and new features.
