F4B Troubleshooting: Articulation Stuck
The articulation tip is stuck or will not steer
Straighten the insertion tube first, then try to steer again.
If the tip still will not turn, lift the tube, hold it just below the bending section, and shake it gently a few times. Then try to steer again.
If the tip still does not respond after that, contact Ralcam after-sales support for help.
Do not force the articulation control while the tip is unresponsive.
