Temperature protection: in TC mode, if the actual temperature of coil reaches the set temperature, the device shows "Temp Protection".
Weak battery alert: in VW / TC mode, when the device installed with an atomizer is working and the voltage of the battery is below 2.9V, the device shows "Weak Battery". Meanwhile, the output power will be reduced accordingly.
Low power alert: if the power of the battery is lower than 10 percent, the power symbol on the screen will flash.
Imbalanced alert: when the difference between the maximum and minimum cell voltage is equal or greater than 0.3V, the OLED screen will display "Imbalanced Batteries" after inserting the USB cable. Then please take out the cells to charge or replace with freshly charged cells. 
Check USB alert: when the voltage of the USB charger is equal or greater than 5.8V, the OLED screen will display "Check USB Adapter" after inserting the USB cable or vaping.
Check error alert: when no current is detected in charging state, the OLED screen will display "Charge Error".
Check battery alert: when one of the cells is not installed correctly, the OLED screen will display "Check Battery". 

How to Use: 
1. Power ON / OFF: press the back cover lock button and the back cover will pop out automatically. Then put two 18650 batteries into the battery body. Aiming the two notches of the back cover at the ones on the battery body, press the top part and then the bottom part. Press the fire button 5 times in quick succession to turn the device on and off.

3. Key Lock Function: while RX2 / 3 is on, simultaneously press the two regulatory buttons. This will switch between Key Lock and Key Unlock function.
4. Micro USB Port Function: the USB port can be used for charging and upgrading firmware. It is better to take out the batteries and charge them through the external charger.
5. Switch the Display Mode: by pressing the left and right regulatory buttons simultaneously in shutdown state, the screen display will rotate 180 degrees. You can then view the screen from two kinds of the angle through this operation.
6. Shift among VW / TC - Ni / TC - Ti / TC - SS / TCR Mode: 
(1) Press the fire button 5 times to turn the device on. The OLED screen presents 4 rows of information;
(2) Press the fire button 3 times, the mode indication will flash to indicate you enter into the menu. Press the right regulatory button to switch between VW / TC - Ni / TC - Ti / TC - SS / TCR Mode.
