3.5 Screen saver

USN 52R/USN 52L are equipped with a screen saver in order to extend the life of the display screen and the operating time of the batteries. If your instrument is on, and you have not pressed a key, and no positive gate violation has occurred for 30 minutes the text/graphics portion of the display will be erased and only a live A- scan trace will be displayed. If a frozen image is being displayed when the unit goes into screen saver mode, the frozen image will be lost. To exit the screen saver mode, you must press a key or have a positive gate violation. The keypress to exit screen saver mode will not change any instrument settings. When screen saver mode is exited, the screen will return to the display which was present before.
