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.
On the left side of the bar you’ll see a circuit board with a small ribbon cable attached where a circuit board is protruding.
If the ribbon is not connected to the circuit board within the tube it needs to be reconnected. Insert the circuit ribbon cable into the black circuit board ribbon connector located on the circuit board within the tube.
Afterwards, lock the circuit board ribbon connector so that the circuit ribbon cable is secure, and does not move.
Make sure the roller bar is placed evenly above the two metal leaf springs, and put the caps that hide the ends of the roller bar back on.
Then make sure to push the caps outwards towards the ends. Confirm that the caps click into place.
If this does not solve your problem, please contact us for an exchange on your unit.
