4.1. Keyboard Usage
The full-size keyboard features a standard QWERTY layout with a dedicated number pad. The retro round keycaps provide a comfortable typing experience.
- Ergonomic Design: The keyboard includes a folding holder and anti-slide pads on the underside. Adjust these stands to achieve an optimal typing angle, which helps reduce wrist strain during extended use.
- Multimedia Keys: Utilize the function keys (F1-F12) in combination with the 'Fn' key for quick access to multimedia controls and other system functions.

4.2. Mouse Usage
The contoured mouse is designed for comfortable use over long periods. It features standard left/right click buttons and a scroll wheel.
4.3. Auto-Sleep Feature
To conserve battery life, both the keyboard and mouse are equipped with an intelligent auto-sleep function. After 8-10 minutes of inactivity, the devices will automatically enter sleep mode. To wake them up, simply press any key on the keyboard or click a mouse button.

5. Maintenance
5.1. Cleaning
The keyboard features detachable keycaps, making cleaning convenient.
- Gently remove the keycaps. A keycap puller (if included) or a small tool can assist.
- Use a soft brush (a cleaning brush may be included) or compressed air to remove dust and debris from beneath the keycaps and from the keyboard surface.
- Wipe the keycaps and the keyboard surface with a soft, damp cloth. Ensure no moisture enters the internal components.
- Allow all parts to dry completely before reattaching the keycaps.

5.2. Battery Replacement
When the devices stop responding or exhibit intermittent connectivity, it may be time to replace the batteries. The estimated battery life is up to 18 months, but this can vary based on usage.

- Insert a new AA battery, observing correct polarity.
- Close the compartment cover.
6. Troubleshooting
- No Response: Ensure batteries are correctly installed and charged. Check that the USB nano receiver is securely plugged into your computer.
- Intermittent Connection: Move the keyboard and mouse closer to the USB receiver. Ensure there are no large metal objects or other wireless devices interfering with the 2.4G signal. Replace batteries if they are low.
- Keys Not Working: If specific keys are not responding, try removing and re-inserting the keycap to ensure it is properly seated. Clean any debris around the key switch.
