Step 1:Use a hammer to drive the steel needle on the invisible nail into the wall, and pay attention not to break the small tail of the invisible nail during the beating process.
Step 2:The steel needle is parallel to the invisible nail. When there is no protrusion, it is considered to be knocked, and the steel needle will enter the wall for about one centimeter.
Step 3:After adjusting the time of the wall clock, it can be hung on the invisible nail after installing the battery. When hanging, the clock is slightly higher than the invisible nail and then hangs down, which is easier to hang.
Special tip:Quartz clocks need to use carbon batteries, do not use alkaline batteries such as Nanfu and Duracell.
