Installation instructions: Please ensure the wall where the clock is to be mounted is suitable. Drill a 7mm hole using a power drill. For brick and cement block walls you will need a masonry bit. Drill the hole at least 5cm into the wall. Push a rawlplug (plastic wall plug) into the hole. You may need to use a hammer to lightly tap it into place. The plug should sit flush with the wall. Using a cross head screwdriver, screw a screw into the rawlplug, leaving no more than 5mm protruding. Check with your hand that the screw is secure. If so, then mount the clock by lining up the screw with the screw hole/hanger on the clock mechanism. Adjust to ensure it is aligned correctly and secure. Requires AA battery (not included). If unsure on how to install this item, hire the services of a professional.
