How do I lock or unlock the vaping function on the RPM 40?
Quickly press the Fire Key 3 times to lock or unlock the vaping function. You can also press the UP and DOWN buttons simultaneously to lock or unlock the wattage adjustment function separately. These are two distinct lock functions on the device. (Page 6)
