How do I know how much battery is left?

Your Crayon has an LED that indicates the battery status. Press the power button to check the battery.

LED Color	Status
Green	Battery is sufficient and above 10% charge
Breathing green	Charging
Red	Battery has less than 10% charge.
Blinking red with battery check	Battery has less than 10% charge
.Blinking red without battery check	Battery is less than 5%(critical) and please recharge immediately

NOTE: If the LED turns red when you first turn the pen on, charge before using.
