8. Troubleshooting

8.1 Keypad Not Responding

• Wired Mode: Ensure the Type-C cable is securely connected to both the keypad and your device. Try a different USB port or cable.
• 2.4G Wireless Mode: Ensure the 2.4G receiver is properly plugged in and the keypad is switched to 2.4G mode. Try re-pairing by unplugging and replugging the receiver, then restarting the keypad.
• Bluetooth Mode: Ensure Bluetooth is enabled on your device and the keypad is in Bluetooth pairing mode. Forget the device in your device's Bluetooth settings and try pairing again.
• Battery: Check if the battery is charged. Connect the keypad via Type-C cable to charge it.

8.2 RGB Lighting Not Working

• Ensure the keypad is powered on and connected.
• Check if the lighting is turned off or set to minimum brightness via function key combinations or VIA software.
• If using VIA, ensure the lighting settings are correctly configured and applied.

8.3 Keys Not Registering

• If only specific keys are not working, the switch might be faulty or improperly seated. Try removing and re-inserting the switch (refer to Section 4.2.1).
• If multiple keys are affected, try resetting the keypad (if a reset button or function exists, otherwise disconnect and reconnect).

9. User Tips

While no specific user reviews or Q&A were provided, here are some general tips for mechanical keypad users:

• Experiment with Switches: Since the Panda20 is hot-swappable, don't hesitate to try different switch types (linear, tactile, clicky) to find what feels best for your typing style.
• Leverage QMK/VIA: Take full advantage of the QMK/VIA customization. Remap keys for specific software, create macros for repetitive tasks, or personalize your lighting effects.
