【National】National Strobe autopana PE-2801　with case I checked the operation by inserting batteries before listing. When I turned the switch ON, I heard the power-on sound. In that state, when I pressed the flash button (FLASH) below the switch, it flashed. I have not checked it by connecting it to a camera. I am a novice and do not know the details of how to use it, so please consider it as-is. I will not be able to answer any questions. Thank you for your understanding. As it is a very old item, I would appreciate it if those who understand this would purchase it. It is a used item, and because it is a novice inspection, there may be oversights. Please refrain from purchasing if you are looking for perfection. Please read the profile before purchasing.
