Contour vape batteries are the most discreet devices on the market. To use a Contour battery, simply thread your 510 threaded cartridge onto an included ring and drop it into the cartridge slot on the battery. To use magnetic carts with the Contour 3 you don't need a connector, simply drop the cartridge into the vape. There is a small metal lip next to the magnet, just make sure you are not caught on the lip.
Instructions for all Contour batteries
Power on or off: Click the button 5 times quickly (5 times within 3 seconds).
Preheat your cartridge: Click the button 2 times.
Change power level: Click the button 3 times. (Blue = Low, Green = Med, Red = High)
Charging: Plug the included micro usb cord into the slot. Charge the battery with a wall charger (not in your car or with a computer). When it is charging, the power light will be red. When it is fully charged, the red light will turn off.
Power the device on, insert a cartridge (with connector ring if necessary) into the slot. Press and hold the power button and inhale on the mouthpiece.
If you are not getting any vape, you do not have a good electrical connection due to dirt or oil. Often times, simply twisting your cartridge to ensure a good connection is all it takes. If you still have no connection, clean the contacts by moistening a cotton swab with iso alcohol and gently clean the bottom of your cartridge, magnetic connector and inside the battery (where it connects to your cartridge or ring). Let it air dry and continue use.
