Using the Black Diamond Moji+ Lantern is a breeze. Just use the two - button interface to turn it on and select the light mode you want. You can choose from solid or strobing white light, full - spectrum colors, or the campfire mode. To attach it quickly, use the 4 magnets on the lantern. For hanging, use the double - hook hang loop inside your tent. When it comes to power, you have two options. You can either use alkaline batteries or a rechargeable BD 1500 Li - Ion battery (you'll need to buy the rechargeable battery separately). If you're using the rechargeable battery, make sure to charge it fully before your trip. As for maintenance, keep the lantern dry as it's IPX 4 Stormproof but still don't submerge it. Wipe it clean with a dry cloth after each use. Also, when not in use, store the lantern in a cool, dry place. If you're using alkaline batteries, remove them when the lantern won't be used for a long time to prevent corrosion.
