It includes Bluetooth Low Energy (LE) and 2.4GHz wireless connection options for maximum flexibility, and 50% of overall plastic is recycled material. The Pro Fit Ergo TB450 also features long battery life, patented ball ejection system for easy cleaning, and precision opticaltracking technology. If you’re experiencing issues with your trackball mouse such as stickiness, slowness, or scrolling problems, it’s likely that it needs cleaning. Follow the steps below to clean and lubricate your trackball, restoring its optimal functionality. 1. Remove the ball from the socket using the eject button on the bottom of the trackball frame. 2. Clean the ball and trackball frame with a damp cloth or rubbing alcohol and allow them to dry. 3. Lightly lubricate the ball with a non-acidic lotion. We recommend using an oil-based lotion such as Vaseline for the best result. Evenly rub a pea-sized amount of lotion into the palms of your hands and roll the ball across the lotion on your hands until the ball is evenly lubricated. 4. Gently push the ball back into the socket. If the ball feels a little sticky, simply roll it around in the socket until it moves freely.
