Joyetech eVic-VT Operation Sounds
EVic-VT has some characteristic sounds in operation. Thesesounds are very low in volume, and can typically only be detected by holding thedevice close to the ear.
EVic-VT boost circuit inductor emits acontinuous high-frequency buzz, and the switching system that detects atomizerresistance produces an intermittent ticking noise rather like that of a quartz watch. These noises are normal, and should not cause concern in any device that isotherwise functioning normally. When the device goes into standby after a period of 3 minutes without use, or if the power button is pressed 5 times, all such noises will immediately cease.
