PRECAUTIONS IN LAMP SIGNALING.
Don’t leave the lamp cover open when not in use.
Don’t forget to open it when you start to transmit.
Don’t touch the mirror. If necessary, it should be cleaned by wiping with gauze or cotton or wiped with clean water.
Don’t pull the wire cable fastened to the bottom of the lamp when removing from the box.
Don’t return broken or burned-out globes to the pouch, but throw them away unless ordered to turn them in. Don’t use the lamp for illuminating purposes.
Don’t neglect to keep a constant watch on the stations with which you are supposed to communicate.
