How to Use 

Power on/off: Screw off the battery cap, put one high-rate 18650 cell (positive side down and negative side up ) into iStick Pico and finally screw on the battery cap. The device can be powered on/off by pressing the fire button 5 times. 

Vaping: Long press the fire button to take a puff.

Stealth on/off: Press the fire button and down button simultaneously when the device is powered on to switch between Stealth On and Stealth Off mode. In Stealth Mode ON, you can vape with the OLED screen off and you can press the fire button one time to see current settings.

Adjustment buttons lock/unlock: Keep pressing up button and down button simultaneously for two seconds when the device is powered on, then the up and down buttons will be locked and the screen will display "LOCK". In the same way, the up and down buttons can be unlocked and the screen will display "Unlock". Through this operation, you can protect the buttons from unintentional presses and prolong their lifespan. 

Switch display mode: Keep pressing up button and down button simultaneously for two seconds when the device is powered off, the screen display will rotate 180 degrees. You can view the screen from two different angles through this operation. 

Switch vaping modes: When the device is powered on, press the fire button 3 times in quick succession, the device will display current vaping mode. Press the up or down button to switch among VW, Bypass, TC-Ni, TC-SS, TCR-M1, TCR-M2, TCR-M3 modes and then press the fire button one time or stay in the interface about 10 seconds to confirm the vaping mode you choose.

• In VW mode: When set in VW mode, the device can support a coil whose resistance is within the range of 0.1Ω-3.5 Ω. 
• Adjust Wattage: In this mode, the output wattage can be adjusted from 1W to 75W by pressing up button or down button, up button to increase and down button to decrease. Long press up button or down button can rapidly increase or decrease wattage level. 
• In Bypass mode: When set in bypass mode, the device can support a coil whose resistance is within the range of 0.1 Ω -3.5Ω. Direct output voltage system is applied in this mode. The higher the battery level, the higher the output voltage. 

• In TC-Ni/TC-Ti/TC-SS/TCR(M1,M2,M3) Mode: When set in TC-Ni/TC-Ti/TC-SS mode, the device can support Nickel 200, Titanium, and Stainless Steel 316 coils. In TCR (Temperature Coefficient of Resistance) mode, the device can support different temperature control coils within different TCR value ranges and you can set the TCR at different values within proper range.(Resistance Range: 0.05Ω-1.5Ω). 
  

The Setting of TCR Mode (M1, M2, M3): When the device is powered off, keep pressing the fire button and the up button simultaneously, then you will enter into the TCR (M1,M2,M3) set menu: 

• Press the up or down button to choose among M1,M2 AND M3 modes; 
• Press the fire button one time to confirm the mode you choose; 
• Press the up or down button to increase or decrease the TCR value according to the material of the coil you use; 
• Keep pressing the fire button or stay in the interface for about 10 seconds to confirm your setting. 

Adjust Wattage: In TC-Ni/TC-TI/TC-SS/TCR (M1,M2,M3) mode, the output wattage can be adjusted from 1W to 75W. Press the fire button 4 times in quick succession to enter the wattage setting menu and press up or down button to increase or decrease he wattage level. Keep pressing up or down button without looseness to rapidly increase or decrease the wattage level. 

Adjust Temperature: In TC-Ni/TC-TI/TC-SS/TCR (M1,M2,M3) mode, temperature can be adjusted from 100°-315°C or 200°-600°F by pressing up button or down button, up button to increase and down button to decrease. Each press of the up or down button will increase or decrease the temperature setting by 5°C or 10°F. Keep pressing up button or down button without looseness can rapidly increase or decrease temperature setting.  

Shift between °C and °F: If you increase temperature to 315°C, and continue to press the up button, the temperature reading will automatically change to the lowest Fahrenheit (200°F ). Equally, if the temperature is set at the lowest Fahrenheit (200°C) and you continue to press the down button, the temperature reading will automatically change o press the down button, the temperature reading will automatically change to the highest Celsius. (315°C). 

Lock/Unlock Resistance: In TC-Ni/TC-TI/TC-SS/TCR (M1,M2,M3) mode, when the device is powered on, keep pressing the fire button and up button simultaneously for two seconds to lock or unlock atomizer "base resistance". The lock sign will appear when resistance is locked and "Ω" symbol will come back when unlocked.  

Properties: 

Atomizer Protection: Each time when vaping time exceeds 10 seconds, the output shuts off automatically with "Over 10s" display on the screen. 

Atomizer Low Alert: When the resistance of coil is lower than 0.1 Ω in VW/Bypass mode or lower than 0.05Ω in TC modes, the screen will display "Atomizer Low". 

Atomizer Short-circuit & No Atomizer Protection: When atomizer short-cicuit occurs, the screen will display "Atomizer Short:. The screen will display "No Atomizer" when there is no atomizer connected.  

Low-Voltage Protection: When the voltage of the cell is below 3.1 Vm the screen will first display "Battery Low: and then "Lock". Charge the cell to unlock the device. 

Temperature Protection: In TC modes, when rhe actual temperatue of coil reaches the set temperature, the screen will display "Temp Protection". You can continue to use the device normally. 

Temperature Alert: If the temperature of device is over alert temperature, the output will shut off automatically and the screen will display "Device Too Hot". You can continue to vape after it cools down. 

Weak Battery Alert: In all vaping modes, when the device is working with an atomizer and the voltage of the cell cell drops blow 2.9V, the screen will display "Weak Battery". Meanwhile, the output power will be reduced accordingly.
