Product Introduction:
1.Long press the "M/T" button to cycle through the working modes. It can be set to six working modes: standard, strong light, super strong, gradual, pulse and
inspection. Because the timing time set for different modes is different, when
switching modes, the timing time will automatically switch. 
2.Short press the "M/T" button to cycle through the timing time. Different working modes have different timing times.
