SM-6T-2-02 APOLLO MISSION SIMULATOR INSTRUCTOR HANDBOOK  1.3.1.16 Closed Circuit Television System.

The closed circuit television (CCTV) is a black and white TV system consisting of three GPL model 800 cameras, three monitor's, and the inter connection between cameras and monitors. The cameras are fixed in the SCM with no zoom capabilities. Each TV camera uses a vidicon tube and operates down to a light level of one foot-candle at the lens. The location of the cameras is illustrated in figure 1-22. Camera 2 is located behind the left shoulder of the trainee in the commander's station. Camera 1 is located near the left foot of this station. Camera 3 is located behind the right shoulder of the trainee in the right couch. Cameras 2 and 3 cover the main display panel, overlapping in the center, and also provide a front view of the G&N lower equipment bay. Camera 1 provides a view of the three trainees in the interior of the SCM.

The three monitors are mounted above the respective flight crew stations at the IOS. Each monitor has controls which are not part of the IOS. Their location is similar functionally to those of any commercial set. The camera controls are located beneath each monitor atop the IOS. These controls are illustrated in figure 1-23, and functionally described in table 1-21. 1-39
