Programming Skills reset to starting position

In rule PSC1 it states you can handle the robot to reset it to a valid starting point and rule PSC2 states you start the robot by pressing a button on the brain or manually activating a sensor. So each time you move the robot back to the starting point can you press any button on the brain or manually activate any sensor to start? For example can you press a button on the brain to start the event and then during a reset back to the start manually activate a sensor to continue?

Yes, this is legal. During retrievals of the Robot during the Programming Skills Challenge you are permitted to interact with your Robot, including pressing buttons or activating sensors.
