- Connect the other end of the cable (USB-A) to an available USB port on your computer. The keyboard will be automatically recognized and ready for use.

2.4G Wireless Connection
- Locate the 2.4G USB receiver (often stored in a compartment on the keyboard's underside or side).
- Plug the USB receiver into an available USB port on your computer.
- Locate the power switch on the keyboard (usually on the back or side) and slide it to the 'ON' position.
- To initiate pairing, press the 'ESC' + 'K' keys simultaneously for approximately 1 second. The indicator light on the keyboard will flash, indicating it is in pairing mode.
- Once successfully connected, the indicator light will turn off, and the keyboard will be ready for wireless use.

Operating Instructions
Indicator Lights
The Aigo A108 keyboard features visible state indicator lights located at the bottom. These four visual status indicators provide a quick overview of the keyboard's power status and current connection method (wired or 2.4G wireless) at a glance.

Battery and Charging
The keyboard is equipped with a durable 1200mAh lithium battery. To charge, connect the USB Type-C cable to the keyboard and a power source. A full charge typically takes about 2 hours. Once fully charged, the keyboard can provide approximately 90 days of usage in wireless mode, based on laboratory test results. Actual usage time may vary depending on factors such as usage intensity and environment.

Key Functions
The Aigo A108 features a 110-key layout, including standard alphanumeric keys, a full row of function keys (F1-F12), navigation keys, and a dedicated numeric keypad. Many keys have secondary functions, often indicated by symbols printed on the keycap. These secondary functions are typically accessed by holding down the 'FN' key (Function key) and pressing the desired key. Refer to the keycap legends for specific combinations, such as multimedia controls or system shortcuts.
Maintenance
General Cleaning
To maintain the cleanliness and functionality of your keyboard, regularly wipe the keycaps and chassis with a soft, dry, lint-free cloth. For deeper cleaning, you can gently remove the keycaps using a keycap puller (if provided) and use compressed air to blow away dust and debris from between the switches. Avoid using harsh chemical cleaners, abrasive materials, or excessive moisture, as these can damage the keyboard's components or finish.
Keycap and Switch Replacement
The Aigo A108 keyboard features a full-key hot-swappable design, allowing you to easily replace 3-pin mechanical switches without soldering. This provides flexibility for customization and repair.
- Removing Keycaps: Use a keycap puller to gently grip the keycap you wish to remove. Pull straight upwards with steady force until the keycap detaches from the switch stem.
- Removing Switches: Once the keycap is removed, use a switch puller to carefully grasp the top and bottom clips of the switch. Gently rock and pull the switch upwards until it detaches from the PCB socket.
- Installing Switches: Align the three pins of the new 3-pin mechanical switch with the corresponding holes on the PCB. Gently press the switch down until it clicks into place. Ensure it is fully seated and stable.
- Installing Keycaps: Place the desired keycap onto the stem of the newly installed switch and press down firmly until it is securely attached.

Troubleshooting
- Keyboard not responding:
- Ensure the keyboard is properly connected in wired mode or that the 2.4G USB receiver is securely plugged into your computer.
- Check if the keyboard's power switch is in the 'ON' position for wireless mode.
- Verify the battery level and charge the keyboard if necessary.
- For wireless mode, try re-pairing the keyboard by pressing 'ESC' + 'K' simultaneously for 1 second.
- Specific keys not registering:
- Gently remove the keycap and check for any debris lodged under it or around the switch stem. Clean as per the maintenance instructions.
- If using hot-swappable switches, ensure the switch is fully and correctly seated in its socket. You may try removing and re-inserting the switch.
- Wireless connection issues (lag, disconnections):
- Ensure the keyboard is within optimal range of the USB receiver (typically within 10 meters, unobstructed).
- Avoid potential interference from other 2.4Ghz wireless devices (e.g., Wi-Fi routers, cordless phones).
- Try plugging the USB receiver into a different USB port on your computer.
- Ensure the keyboard battery is sufficiently charged.
User Tips
- PBT Keycap Advantage: The PBT keycaps on your Aigo A108 are known for their durability and resistance to shine over time, providing a consistent and comfortable typing experience.
- Customization with Hot-Swap: Leverage the hot-swappable feature to experiment with different 3-pin mechanical switches. This allows you to fine-tune the typing feel and sound to your personal preference for various tasks like gaming or typing.
- Seamless Dual-Mode: Utilize the dual-mode connectivity to adapt to your environment. Use wired mode for competitive gaming to minimize latency, and switch to 2.4G wireless for a clutter-free desktop and general use.
- Battery Management: While the keyboard boasts a long battery life, it's good practice to charge it regularly, especially if you primarily use it wirelessly, to avoid interruptions during use.
