Your power meter will need a good charge before your first use. Your charger needs to be aligned properly to charge, so take note of the images below and how the charger is attached.
When the charger is aligned properly, a green light will flash on the charger to let you know it is working properly.
You power meter needs to charge for at least four hours to give it a full charge.
The green LED on your power meter will blink and let you know how much battery is left. 5 blinks = 100%, 4 blinks = 80%, 3 blinks = 60%, 2 blinks = 40%, 1 blink = 20%. If your power meter has less than 10% battery left, it will give a rapid blink and shutdown.
