Help a friend use Nikon D700: I am a beginner in light painting. After exposure, the camera shoulder screen has some garbled words that I can't understand! All the buttons are broken!

It's normal to take photos at Gate B, and the exposure time+processor delay is normal, so are our usual photos. The shutter of1100 and the processing time of1100 can only get photos, but the time is too short, and we can't get photos at Gate B. If the landlord exposes for one hour, you have to wait for one hour after exposure, but it is also feasible to shut down forcibly. That's what I did when I photographed the stars. Otherwise the battery can't stand it! ! !
