Using this keyboard is easy. First, if you want to use Bluetooth, turn on your PC's Bluetooth function and pair it with the keyboard. If you prefer a wired connection, just plug in the USB - C cable. Once connected, start using the over 60 color - coded shortcuts designed for Adobe Premiere Pro to speed up your video editing. You can adjust the backlight brightness by pressing the dedicated key. For battery life, if you don't need the backlight, you can enjoy up to 300 hours of use. When the battery is low, charge it using the provided USB - C cable, which takes about 4.5 hours to fully charge. As for maintenance, keep the keyboard clean by gently wiping it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Also, don't expose it to extreme temperatures or moisture. If you encounter any issues, refer to the user guide that comes with the keyboard.
