Key Features

Figure 2: Lightweight Design
This image illustrates the lightweight nature of the mouse, comparing its weight to an S-sized egg, both weighing approximately 50g. The text emphasizes that the mouse is designed for easy operation with light force, reducing fatigue during prolonged use.
This mouse features a lightweight design, weighing approximately 50g, allowing for comfortable operation with minimal effort, reducing fatigue during extended use.

Figure 3: BlueLED Technology
This image demonstrates the versatility of the BlueLED sensor, showing the mouse operating effectively on both a cloth surface and a paper surface, indicating it does not require a specific mouse pad.
The mouse is equipped with a BlueLED sensor. Unlike traditional optical mice that use red light, BlueLED's shorter wavelength allows for more accurate reflection of light even from small irregularities and dust, enabling comfortable use on various surfaces without needing a specific mouse pad.

Figure 4: Symmetrical Design
This image highlights the symmetrical design of the mouse, indicated by a central dashed line, emphasizing that its shape is suitable for both left and right-handed users.
The mouse features a symmetrical design, making it comfortable for both left and right-handed users.

Figure 5: 1000 Count Resolution
This image explains the 1000-count resolution, showing a scale of counts from 0 to 4000. It suggests that 1000 counts are ideal for smooth operation in applications like Excel/Word, while lower counts (400-800) are suitable for web browsing and higher counts (2000+) for gaming.
With a resolution of 1000 counts, this mouse provides smooth and precise cursor movement, suitable for various tasks.

Figure 6: OMRON Switch
This image shows a close-up of the OMRON switch used in the mouse, highlighting its internal mechanism. The text indicates that OMRON switches are known for their reliable click feel and durability.
The mouse utilizes OMRON switches, known for their excellent click feel and durability.
The 2.4GHz wireless connection allows for a working range of approximately 10 meters on non-magnetic surfaces and 3 meters on magnetic surfaces like steel desks.
Maintenance
- Cleaning:
To clean the mouse, gently wipe the surface with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Do not use harsh chemicals or immerse the mouse in liquid.
- Battery Replacement:
When the battery indicator lamp flashes or the mouse performance degrades, it's time to replace the battery. Follow the battery installation steps in the 'Setup' section.
- Receiver Storage:
When transporting the mouse or not using it for an extended period, store the micro USB receiver inside the mouse's battery compartment to prevent loss.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Mouse does not respond. | Power switch is OFF. Battery is depleted. Receiver is not properly connected. | Slide the power switch to 'ON'. Replace the battery. Ensure the receiver is fully inserted into the USB port. Try a different USB port. |
| Cursor movement is erratic or jumpy. | Sensor is dirty. Using on an unsuitable surface (e.g., clear glass). | Clean the sensor lens on the bottom of the mouse with a soft cloth. Use the mouse on a non-reflective, opaque surface. |
| Wireless connection is unstable. | Distance from receiver is too far. Interference from other wireless devices. | Reduce the distance between the mouse and the receiver. Move the mouse away from other wireless devices (e.g., Wi-Fi routers, cordless phones). |
