Setup
1. Charging the Numpad
Before initial use, fully charge the Keychron Q0 Max. Connect the provided Type-C to Type-C cable to the numpad's USB-C port and to a power source. The LED indicator will show charging status.
2. Connecting the Numpad
The Q0 Max supports three connection modes: 2.4 GHz wireless, Bluetooth 5.1, and wired USB-C.
- 2.4 GHz Wireless:
- Locate the 2.4 GHz receiver (USB-A dongle) in the package.
- Plug the receiver into an available USB-A port on your computer. If your computer only has USB-C ports, use the provided Type-A to Type-C adapter.
- Switch the mode toggle on the side of the numpad to 'G' (2.4 GHz mode).
- The numpad should automatically connect.
- Bluetooth 5.1:
- Switch the mode toggle on the side of the numpad to 'BT' (Bluetooth mode).
- On your computer or device, enable Bluetooth and search for new devices.
- Select 'Keychron Q0 Max' from the list of available devices to pair.
- The numpad can store up to three Bluetooth profiles. Use the Fn + 1/2/3 keys to switch between paired devices.
- Wired USB-C:
- Connect the provided Type-C to Type-C cable from the numpad's USB-C port to a USB-C port on your computer.
- Switch the mode toggle on the side of the numpad to 'Cable' (wired mode).
- The numpad will function as a wired device and charge simultaneously.

Operation
1. Basic Key Functions
The Q0 Max functions as a standard numeric keypad. Keys are pre-programmed for typical numeric input and arithmetic operations. The 'M1' through 'M5' keys on the left column are macro keys, and the rotary knob provides additional functionality.
2. Customizing with QMK/VIA
The Keychron Q0 Max is fully compatible with QMK firmware and VIA software, allowing for extensive customization of key functions, macros, and RGB lighting.
- Download VIA Software: Visit the official Keychron website to download the latest VIA software or use the web-based Keychron Launcher.
- Connect Numpad: Ensure your Q0 Max is connected to your computer via USB-C cable for VIA detection.
- Key Remapping: Use the VIA interface to remap any key, assign macros, or configure the rotary knob. The software provides a visual layout of the numpad for easy customization.
- Lighting Control: Adjust RGB effects, brightness, and colors through the VIA software.

Maintenance
1. Cleaning
To clean your numpad, disconnect it from your computer. Use a soft, dry cloth to wipe the aluminum case. For keycaps, a damp cloth with mild soap can be used, ensuring no liquid enters the switches. Use a keycap puller to remove keycaps for thorough cleaning.
2. Switch and Keycap Replacement
The Q0 Max features hot-swappable switches, allowing for easy replacement without soldering.
- Removing Keycaps: Use the provided keycap puller to gently remove keycaps by hooking onto two sides and pulling upwards.
- Removing Switches: Use the provided switch puller. Align the prongs with the clips on the top and bottom of the switch, squeeze, and pull upwards.
- Installing Switches: Ensure the switch pins are straight. Align the pins with the holes on the PCB and press down firmly until the switch clicks into place. Do not force switches if they don't align, as this can bend pins.
- Installing Keycaps: Align the keycap stem with the switch stem and press down gently until it is secure.
Troubleshooting
- Numpad Not Responding:
- Ensure the numpad is charged.
- Check the connection mode switch (2.4 GHz, BT, or Cable) matches your connection method.
- For 2.4 GHz, ensure the receiver is properly plugged in.
- For Bluetooth, ensure Bluetooth is enabled on your device and the numpad is paired. Try re-pairing if necessary.
- For wired, ensure the USB-C cable is securely connected to both the numpad and your computer.
- Keys Not Registering:
- If individual keys are not working, the switch might be faulty or improperly seated. Use the switch puller to remove and re-insert the switch.
- Ensure no debris is lodged under the keycap or switch.
- VIA/QMK Software Issues:
- Ensure the numpad is connected via USB-C cable when using VIA for programming.
- Download the latest version of VIA software or Keychron Launcher from the official website.
- Restart the software and reconnect the numpad.
- Battery Drains Quickly:
- High RGB brightness and complex lighting effects consume more power. Reduce brightness or simplify effects to extend battery life.
- Ensure the numpad is turned off or enters sleep mode when not in use.
