3.Shift Between VW/TC/NI/TI Mode

The OLED screen presents 4 rows of information: TC/Ni/Ti and VW mode. While the device is on, the OLED screen will show VW Mode.

How to use taste control mode?

Take some puffs to find your desired vaping taste before switching to TC mode. Then keep pressing”T” button.

When a new atomizer is directly connected in TC mode, the screen will display “TC SETUP NEED TO LEARN MORE THAN 2’S”. Then the device needs to go back to VW mode to learn.

Keep pressing the “T” button, the screen will switch from TC mode to VW mode.

Manage the mode of taste control:

Norm Mode:

Calibrate your favorite taste at a wattage firstly, then setting to TC mode, temp percentage shows 100%, that’s is your favorite wattage chosen before.

Hard Mode:

Press up button to increase temp percentage 100% to 101%-102%-…-110%, means the working wattage is increased by percent too.

Soft Mode:

Press down button, temp percentage will decrease from 100% to 99%-98%-…-80%, working wattage decrease by percent.


When switch to TC mode on maximum wattage, the temp percentage maximum only can reach 100%. When switching to 100%, the screen will display “MAX WATTAGE “.

To reach the maximum watts output, the battery should be 20A or above.

For better Taste Control, please make sure the atomizer base is well connected to Solo Mini and engineers suggest to learn before entering either TC mode.

Keep power off when rebuild the RDA on Solo Mini.

Please make sure the new atomizer has cooled down to room temperature. Otherwise the device will misread the resistance.

When the resistance changes more than 0.06Ω, after re-install the tank, a message will be displayed on the screen. Choose “NEW” or ”SAME” by using ” UP” and “Down” buttons and “T” button to confirm.

When the resistance changes more than 0.15Ω, the screen will show “NEW ATOMIZER” and the device will automatically switch to VW mode. The default wattage is 15W.

If you take off the tank from Solo Mini for refilling or any other purpose, please go back to VW mode to learn again.

Press up/down button to set the temperature value, coil temperature can be adjusted from 300-600℉/150-315℃ range. The temperature will be increased in 5℉ after each press.

The temperature loops between °F and ℃.

4.Reset Function

What’s the reset function?

When the atomizers don’t work accurately in Ni/Ti TC mode, vapers can comply. Reset to read the resistance of atomizer again.

Notice: Please make sure the atomizer is cooling down when reset.

How to reset?

Pls shutdown the Solo Mini device, Press the fire button first then along with the “T” button, the screen will show “reset ok “So it means having cleared the memories of the before used atomizers. When you power on the device, it will show “New Atomizer”.

The device does not have enough e-liquid. The indicator will flash and the device will stop working 15 seconds. Refill the e-liquid and go back to wattage mode to learn again.

If E-liquid is enough, but keep flashing that means the learning time was not enough and the device needs to go back to wattage mode to learn again.

If the device overheats, wait a while until it can be used again.

6.Malfunction Indication And Protection

Time out protection: When the button is pressed for over10 seconds, the output will shut off and the OLED screen will display “TIME OUT”.

Atomizer short-circuit protection: When atomizer short circuit occurs, the OLED screen will display “SHORTED”.

Low resistance protection: When the resistance is lower than 0.08ohm, the OLED screen will display “  OHMS TOO LOW”. When the resistance is higher than 3ohm, the OLED screen will display “OHMS TOO HIGH”.

Low power alert: When battery voltage is below 3.2V, the device shows “ LOW BATTERY”.

PCB temperature overheat protection: When the temperature of device is too high, the output

will shut off automatically and the screen will display “ PCB TOO HOT”.
