1. Power-on & access to atomizer: it enters standby mode after 4 LED lamps flash 2 times in a turn (running horse lamp lasts 3s).
2. Booting: 4 LED lamps flash 3 times after the smoking button pressed for 5 times within 2S; the current gear lamp is displayed (about 2s) after booting, and no operation within 2s enters into standby mode.
3. Power-off:4 LED lights are on for 2s to power off after the smoking button pressed for 5 times within 2S. It has five-on and five-off functions.
4. LED light power indicator: click the power button to display the battery level in standby mode.
a: The first, second, third and fourth lights are on when the current power is between 75% and 100%.
b: The first, second and third lights are on when the current power is between 55% and 75%.
c: The first and second lights are on when the current power is between 25% and 50%.
d: The first light is on when the current power is between 1% and 25%.
5. Smoking preheating: when pressing the power button twice within 2s to start preheating, the output voltage is 2.0v in the state of power-on, and the preheating time is 15s; 4 lights are on in turn when preheating. When preheating is over, the current lamp is on (2S) and smoke is allowed when pressing the power key.
6. Power adjustment: under the power-on state, the current-voltage light flashes after quickly pressing the power button 3 times within 2s, and gears switch circularly after clicking the smoking button.
a. The output voltage of the first LED lamp is 3.2V.
b. The output voltage of the second LED lamp is 3.5V.
c. The output voltage of the third LED lamp is 3.8V.
d. The output voltage of the fourth LED lamp is 4.0V.
e. The power key can be circulated in turn when pressed; no operation within 3S will be out of gear adjustment, showing the current gear lamp about 2S.
7. Memory function: It can be turned off with any gear, and will remember the last smoking gear after rebooting.
8. The protective function of smoking time limit: smoking is prohibited after a puff of smoke at any gear more than 11s and LED light flashing 5 times after 11s.
9. Protective function of high & low resistance, open & short circuit: 4 LED lights flashing 10 times at the same time indicates no loading.
10. Battery low-voltage protection: smoking is not allowed, when the battery voltage is less than 3.3 V. It indicates no loading and enters dormant mode when the first power lamp flashing 20 times rapidly.
11. Normal-smoking mode: the indicator light is gradually on with its corresponding voltage in smoking state after pressing the corresponding gear. After releasing the button, it stops working and the gear indicator light fades out gradually.
