A touchpad is a pressure-sensitive device that can easily be damaged if not properly protected. Therefore, the following points should be noted when using it: 1. Avoid allowing the touchpad to come into contact with dust, liquids, or oils; 2. Do not touch the touchpad if your fingers are dirty; 3. Do not press heavy objects onto the touchpad or other buttons; 4. Ensure that your hands do not have excessive sweat or moisture, as excessive humidity can cause the indicator device to short-circuit. It is essential to keep the surface of the touchpad clean and dry for normal use; 5. Do not rest your hand or wrist on the touchpad while typing or using it. Since the touchpad can detect any movement of the fingertips, placing your hand on the touchpad can result in poor response or slow actions; 6. Use only one finger for operation; using multiple fingers simultaneously can cause the touchpad to produce incorrect information.
