How do I change the vaping mode on the device?

When using 0.6/0.7/0.8/1.0/1.2Ω pods, click the power button 3 times in 2 seconds to set the vaping mode, then click again to choose P (POWER), N (NORMAL), or E (ECO) mode. Wait 3 seconds to save the current status. For 0.4Ω pods, this accesses power wattage settings instead. (Page 6)
