To use this FC Barcelona wall clock, first, find a suitable spot on your bedroom wall. Make sure it's at a good eye - level. Then, open the back cover and insert 1 x AA battery (you'll need to buy the battery separately). Hang the clock on the wall using the provided hook. Keep the clock away from extreme heat or moisture to avoid damage. If the clock starts to slow down, replace the battery. Wipe the clock gently with a dry cloth to keep it clean.
