3.1 Initial Charging

Before first use, it is recommended to fully charge your Keychron B1 Pro keyboard. Connect the provided USB Type-C cable to the keyboard's charging port and the other end to a USB power source (e.g., computer USB port, wall adapter). The charging indicator light will show the charging status.

3.2 Connectivity Modes

The B1 Pro supports three connectivity modes: 2.4GHz wireless, Bluetooth 5.2, and wired USB Type-C. Use the switch located on the side of the keyboard to select your desired mode.

• 2.4GHz Wireless: For optimal performance and a 1000 Hz polling rate, plug the included 2.4GHz USB dongle into your device's USB port. Switch the keyboard to '2.4G' mode.
• Bluetooth: The keyboard can connect to up to three Bluetooth devices simultaneously. Switch the keyboard to 'BT' mode. To pair, press and hold 'Fn' + '1' (or '2', '3') until the indicator light flashes, then search for 'Keychron B1 Pro' on your device and connect.
• Wired: Connect the USB Type-C cable directly from the keyboard to your device. Switch the keyboard to 'Cable' mode.

6. Troubleshooting

6.1 Connectivity Issues

• Keyboard not connecting: Ensure the keyboard is charged. Check that the mode switch (2.4G, BT, Cable) is set correctly. For Bluetooth, ensure your device's Bluetooth is on and the keyboard is in pairing mode. For 2.4GHz, ensure the dongle is securely plugged in.
• Intermittent connection: Move the keyboard closer to your device. Avoid sources of interference (e.g., other wireless devices, large metal objects).

6.2 Keys Not Responding

• Specific keys: Check for any debris under the keycap. If using the silicone cover, ensure it is properly seated.
• All keys: Recharge the keyboard. Try switching to a different connectivity mode (e.g., wired) to isolate the issue.
