- For the mouse: Open the battery compartment on the underside of the mouse and insert one AA battery (not included), ensuring correct polarity.
- Locate USB Receiver: The 2-in-1 USB receiver is conveniently stored within the battery compartment of the wireless mouse. Carefully remove it.
- Connect USB Receiver: Plug the USB receiver into an available USB port on your computer, laptop, or compatible device.
- Power On: Turn on the mouse using the On/Off switch located on its underside. The keyboard does not have a separate power switch; it activates upon key press after battery installation.

Operating Instructions
- 2.4GHz Wireless Connection: The combo utilizes a stable 2.4 GHz wireless connection, providing a reliable range of up to 33 feet (10 meters) without delays.
- Ergonomic Design: The keyboard features adjustable height tilt legs, allowing you to set an optimal typing angle (e.g., 8-degree tilt) to enhance comfort and reduce wrist strain during prolonged use.

- Silent Operation: Both the keyboard and mouse are designed with silent micro-motion technology. The soft membrane keys provide a quiet typing experience, and the mouse clicks are nearly silent, minimizing distractions.

- Multimedia Hotkeys: The keyboard includes 12 multimedia shortcut keys (F1-F12) for quick access to functions like media playback, volume control, email, and homepage, enhancing productivity.

- Auto Power Saving: To conserve battery life, both the keyboard and mouse automatically enter sleep mode after a period of inactivity (keyboard after 10 minutes, mouse after 25 seconds). Press any key or move/click the mouse to reactivate.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the surfaces of the keyboard and mouse. For stubborn dirt, a slightly damp cloth with mild soap can be used, ensuring no liquid enters the device.
- Battery Replacement: Replace batteries when performance degrades. The keyboard requires one AAA battery, and the mouse requires one AA battery. Dispose of old batteries responsibly.
- Storage: When not in use for extended periods, turn off the mouse to conserve battery. Store the USB receiver inside the mouse to prevent loss.
Troubleshooting
- No Connection/Lag:
- Ensure the USB receiver is securely plugged into a working USB port.
- Check that the mouse is powered on and both devices have fresh batteries.
- Move the keyboard and mouse closer to the USB receiver to rule out range issues.
- Try plugging the USB receiver into a different USB port on your device.
- Mouse Not Responding:
- If the mouse is in sleep mode, move it or click any button to wake it up.
- Verify the battery is correctly installed and has sufficient charge.
- Keyboard Not Responding:
