3. Operating Instructions
Keyboard Usage:

- Function Keys (F1-F12): These keys have dual functions. The primary function is accessed directly, while the secondary function (often multimedia or application shortcuts) is accessed by pressing the 'Fn' key simultaneously with the desired F-key.
- Media Controls: Dedicated media control buttons (e.g., volume up/down, mute, play/pause) are located above the function keys for quick access to audio and video playback.
- Adjustable Tilt Legs: On the underside of the keyboard, you can extend the tilt legs to adjust the typing angle for improved ergonomics and comfort.
Mouse Usage:
- Ergonomic Design: The mouse is contoured to fit comfortably in your hand, suitable for both left and right-handed users.
- Precision Tracking: The optical sensor provides smooth and accurate cursor control on various surfaces.
- Scroll Wheel: Use the scroll wheel for easy navigation through documents and web pages.
4. Maintenance
- Battery Replacement:
- When the battery indicator light on the keyboard (located near the On/Off switch) turns red, or if mouse performance degrades, it's time to replace the batteries.
- For the keyboard, replace the two AA batteries. For the mouse, replace the single AA battery.
- Always use fresh, high-quality alkaline batteries for optimal performance and battery life.
- Cleaning:
- To clean the keyboard, use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Avoid excessive moisture.
- For the mouse, wipe the surface with a soft, dry cloth. Ensure the optical sensor on the bottom is free of dust and debris for accurate tracking.
- Do not immerse either device in water or use abrasive cleaners.
- Storage: When not in use for extended periods, turn off both the keyboard and mouse using their respective On/Off switches to conserve battery life.
