R  (2) LCD (10RA) 
R  The LCD is installed on the aft wall of the cockpit. It lets the 
R  flight crew see the picture from the cameras. 
R  The pictures from camera 1 are shown as a full screen on the LCD and 
R  the pictures from camera 2 and 3 are shown as a split screen. The 
R  pictures from camera 2 are shown left of the LCD screen and the 
R  pictures from camera 3 are shown on right. 
R  If the system gets no signal from the VIDEO push button (16RA) or the 
R  ENTRY REQUEST KEYPAD (Ref. 52-51-00) for 5 minutes the LCD 
R  automatically goes into the standby/power save mode (blank screen). 
R  NOTE : You can change the pin priority to make the screen stay on____ 
R  continiously. 
R  If entry is requested with the keypad (screen is in the standby 
R  mode), the screen automatically comes on and shows the picture from 
R  camera 1. If entry is requested again before 30 seconds after the 
R  last-entry-request the signals are inhibited. This is to let the 
R  pilot use the VIDEO pushbutton to select and see the pictures from 
R  camera 1 or cameras 2 and 3. 
R  If the VIDEO pushbutton is pushed during the first 120 seconds of the 
R  standby/power save mode, the last shown pictures come on. 
R  If the VIDEO pushbutton is pushed after the first 120 seconds of the 
R  standby/power save mode, the picture for camera 1 comes on.
