Some Plazmatic X lighters may arrive with the Child Safety Lock activated.  If your lighter is not turning on, it is most likely because the Child Safety Lock was triggered or activated. The lock will need to be deactivated before the lighter can be used. 

To de-activate Child Safety Lock, press ignition button three times rapidly or until the blue indicator light flashes three times. Your Plazmatic X is now unlocked (see video below for reference). 

If your lighter still does not turn on, try charging it for 30-60 minutes and try the steps above again.
