NOTICE
Forcibly withdrawing the module can permanently damage it
Never pull the dual fan/battery module out abruptly without having released the interlock.
This would break the snap-in hooks and you would not be able to reinsert the module.
2. Tilt the dual fan/battery module forward at an angle and pull out the plastic guide from the
NCU cutout.
3. Remove the battery by rst removing the plug connector and then taking out the battery.
