The first step is to open up the box. Inside your blu Starter Kit you will find:

• One blu pack, which holds five cartridges and charges your batteries on the go!
• Two blu batteries
• One wall chargers
• One USB charger
• One variety pack containing five maximum-strength cartridges

For optimal performance, fully charge the batteries and blu pack before using blu.

Attach a new flavor cartridge to the battery.

Press blu to your lips and inhale. The blue LED light at the tip glows like a real cigarette to let you know it's working.

There are two ways to charge the blu Original pack.

To charge the pack using the wall charger, plug the charger into the nearest outlet. Connect the flat end end of the enclosed USB cable to the charger and the round end to the bottom of the pack. When the blue light at the end of the cord is on, the pack is charging. When the light turns off, your pack is fully charged.

To charge the pack using the enclosed USB charger, unplug the USB cord from the wall charger and connect one end of the cable to the pack and the other to the USB port. When the blue light at the end of the cord is on, the pack is charging. When the light turns off, your pack is fully charged.

Second slot from the right, inside each pack, is a charge port.

Screw the battery into the charge port until it is secure. The blue LED light on your battery will flash and the blue light on the side of the pack will light up. When the light is on, the battery is charging. When the light turns off, the battery is fully charged.

Unscrew the battery from the charge port and store the battery there until needed. Always make sure to unscrew the battery after charging. If the battery is left screwed into the receptor after charging it will drain the charge from the battery.

When the battery is depleted, the blue LED at the end of the battery will blink 30 times intermittently to signal it is ready to be recharged.

To replace the empty battery, secure the cartridge in one hand and unscrew the battery from the cartridge.

Grab the fresh battery from your blu pack and reattach it to the cartridge. When you're finished, recharge the empty battery by screwing it back into the receptor.

Remember to unscrew a newly charged battery from the receptor when the light on the side of your pack goes out.

Note: During use, the LED light will flash 5 times to warn you that you are overusing your blu and you should take a break. This does not affect performance and does not mean you should recharge.

On average, each individual cartridge supplies enough nicotine and premium flavoring to accommodate approximately 250 puffs. When the cartridge no longer produces vapor, you'll know it's time for a replacement.

To replace the cartridge, hold the battery with one hand and unscrew the cartridge from the battery.

Take a new cartridge and screw it onto the battery and you are ready to resume.

Note: If you are leaving your blu for a period of time and not using, unscrew the cartridge from the battery slightly so it is not activated while not in use. If it’s not on, it’s not on – leave the plastic cap and leaf seal on your cartridges until you are ready to use them.
