a lot of the other power meter instructions do stipulate some fairly complicated pre ride criteria, but yes it does take a couple of minutes to get things set up properly, which I believe was Garmin-Cannondales excuse for not using them...
then again it probably takes me 15 minutes to get all my gear on to go for a bike ride, so in the general context of things 2 minutes isn't where I can make the most use of my training time!
I originally used them with an 800 and the "setting of angles" is done by ensuring that the batteries have been removed for >10secs to clear the memory of the pods, then spinning up to >90rpm for a minute or so, levelling the cranks so both pods are downwards and performing a static calibration.
you are then supposed to do a dynamic calibration performed by back pedalling smoothly over 30rpm for 8-10 revs until a message pops up saying "Power Sensor Calibrated”
apparently this supposed to be done every ride, although the battery out bit can probably be left to when moving the pedals between bikes...
