Using this Minecraft wall clock is a breeze. First, find a nice spot on your wall to hang it. You'll need to get one AA battery (it's not included in the package). Open the battery compartment at the back, put the battery in, and close it up. That's it - your clock should start ticking right away. As for maintenance, just use a soft, dry cloth to wipe off any dust every once in a while. Keep it away from water and extreme temperatures. And remember, if the clock stops working, check the battery first. It might just need a replacement.
