Troubleshooting Guide
Problem
What to Check
Low Battery Warning
Recharge the device using a suitable Micro USB cable and 5V/2A USB power source.
No Atomizer / No Load
Remove the tank, check the 510 connection, clean the contact area and attach the tank again carefully.
Short Circuit Warning
Stop using the device. Check the tank and coil for problems before trying again.
Device Gets Too Hot
Stop using it and allow the device to cool fully before continuing.
Adjustment Buttons Do Not Work
The buttons may be locked. Press the power button three times to unlock the adjustment controls.
Weak Power Output
Check the battery level and make sure your wattage setting is suitable for the fitted coil.
Dry or Burnt Taste
Stop vaping and check the e-liquid level and coil. A new coil needs time to soak before use.
Device Will Not Charge
Check the Micro USB cable, charging port and power source. Do not use a damaged cable or damaged device.
Settings Feel Wrong
Open the mode menu and check that the selected firing mode matches your tank, coil and intended settings.

Stop using the device and contact Vaporesso support or a qualified retailer. Do not try to repair the mod yourself.
