Those instructions are a bit vague on operation for what to do and what not. In order to use reverse gear, the unit has to be shifted out of overdrive. If you park the car, it is best to shift it out of OD or the car can roll easily on hills. The clutch in disable switch should allow for a "moving" out shift of OD but shifting it back in may be a different story.

The original R10 electric overdrives had safety features for a good reason. A lot of folks do away with these features when modifying drive trains for these ODs and it can cause breakages if a person doesn't know the operational theory behind these units.
