To use this wall clock, first find a suitable wall location. Make sure it's a flat and stable surface. Then, use a nail or a wall hook to hang the clock. Once it's up, insert the required batteries (not included) to start the modern quartz movement. Keep the clock away from direct sunlight and moisture to prevent damage to the plastic case. If the clock gets dirty, you can gently wipe it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials as they may scratch the clock face or damage the font.
