（3）LCDモニターをオンにするため、LCDモニター下部の電源を長押し
したところ、モニター画面に「CELESTRON Digital Microscope」の
初期画面は立ち上がり、"beep"音も聞こえましたが、そこでフリーズしてしまいます。
もちろん、上部ならびに下部の光源は作動しています。
(3) I pressed and held on the power switch located at the lower part of the LCD monitor in order to turn the LCD monitor on. I heard the "beep" and the initial screen with the logo "CELESTRON Digital Microscope" was displayed on the monitor. However, it freezes there and does not go to the next stage. Of course, both the top and the bottom light sources are in operation.
