● Remove the main unit and back cover, and securely mount it to the wall using screw holes 1 and 2 on the back cover. Use the included AY plug bottle or wood screws. (*The AY plug bottle is a type of plug that can be hammered into a concrete wall, etc.)
● Hook the three removed parts of the watch body into the recessed upper part of the back cover, align the four screw holes at the bottom with the back cover, and secure the watch body firmly with the set screws.
◎ Screws for attaching to standard walls (wood, etc.) are included with your purchase, so anyone can easily install it! You can use it right away.
*Note: For installation on hard walls such as concrete, which require drilling, you can purchase lead plugs separately at a hardware store and embed them in the wall with an electric drill for a sturdy installation. However, if you are unsure of the wall material or thickness, you will need to ask a local construction company to drill the holes for you. Please note that neither the manufacturer nor our store will accept installation requests.
*Please refer to the instructions before installation for product installation instructions.

Masamido, the clock arrived safely.
The rainy season has begun in the Kansai region.
It's hydrangea season. In Japan, there are different seasons, so there are many things to enjoy.
Our school doesn't have clocks, which has been very inconvenient for the children, but I think they will be very happy with this.
I would like to ask for your help again if the opportunity arises, so I would appreciate your help.
