5. Priežiūra
5.1 Rutulinio valdymo pulto valymas
If you experience issues such as stickiness, slowness, or scrolling problems with your trackball mouse, it likely needs cleaning. Follow these steps to clean and lubricate your trackball for optimal functionality:
- Remove the trackball from its socket using the eject button on the bottom of the trackball frame.
- Clean the trackball and the trackball frame with a damp cloth or rubbing alcohol. Allow them to dry completely.
- Lightly lubricate the trackball with a non-acidic lotion. An oil-based lotion like Vaseline is recommended for best results. Evenly rub a pea-sized amount of lotion into the palms of your hands and roll the trackball across the lotion until it is evenly lubricated.
- Gently push the trackball back into the socket. If it feels slightly sticky, roll it around in the socket until it moves freely.
