This will give you instructions on how to move your arm mounted controller in case it has shifted over time
1. Remove the 3X screws with a No. 2 Philips screw drive, this removes the quick connect release tab.
If the below image does not match your machine go to the following for the previous version.
2. Remove the 4X back screws with a T 15 drive followed by the buttons and front cover.
3. Use a T15 key to remove the 1X smaller locator screw on the right side. Then use the T20 key to loosen the 2X clamp screws inside enough to allow the housing to move.
4. The locator screw is meant to line up with the hole on the carbon fiber tube. Once you have it aligned, install the 1X locator screw. This will secure it from moving on the tube.
5. Tighten the 2X clamp screws to fully secure it.
