Please disconnect your RollerMouse Red from any power source before proceeding with the following instructions.
Located on both ends of the bar are two black caps. Push them inwards and you’ll hear them click. Afterwards, pull both caps up and remove them. Keep note which is left and right as they are specific to each side.
WARNING: Do not remove cable ribbon cable located on the left hand side.
Once the caps are off, you can slide the roller off the bar towards the right side.
Use a can compressed air on the internal and external surface of the roller tube, and a Q-Tip with some rubbing alcohol on the inner rim at each end. If moving the roller has resistance after it's been cleaned, apply some lubricant on the inner rim at each end. A Teflon based lubricant is preferred, but a lubricant like WD40 can be used in very small amounts.
If the roller tube is removed. The sensor will be visible in the middle section of the tube with the circuit board located within it. Use a can of compressed air on and around the area of the sensor lens to remove debris.
If desired wipe down the bar with rubbing alcohol, but avoid any other components.
Slide the roller bar back on the tube, and put the side caps back on.
After pressing them down, make sure to push the caps outwards towards the ends.
You should hear them click in place. If no click is heard the caps are not set correctly.
