General Care
To ensure the longevity of your Keychron K13 Pro keyboard, avoid exposing it to extreme temperatures, humidity, or direct sunlight. Do not drop the keyboard or subject it to strong impacts.

Troubleshooting
Connectivity Issues
- Bluetooth Connection Failure: Ensure the keyboard is in Bluetooth mode and discoverable. Check your device's Bluetooth settings and try re-pairing. Make sure the keyboard is charged.
