If it blinks continuously it is telling you that either:

• The cycle is not complete (that is, one of the sensors is indicating that you are not in the fully UP or fully DOWN configuration - try manually cycling the top from up to down and back once or twice)
• The top system is drastically unready to work (low fluid or defective top control module)

Manual operation is demo'd here - be SURE you have the hex key and the top tool, if you don't have the hex key you cant fully complete the cycle when putting the top UP.
