12 At each individual control panel, you must press the start/stop button and the "charging" light will come on. Once the charger has run its cycle and the battery or batteries are charged, the "charged" light will then come on. You then need to once again press the start/stop buttons, as this will shut the charging down. After you've done this, simply turn off the main power, unplug the unit and then disconnect the individual cords. Now you should be ready to ride. Be safe out there, see you in the streets!
