PROTECT OUTPUT
The protect function prevents an output from being switched by other system control panels. For example, if a VTR is record-
ing a program or if the output is feeding a program line, care must be taken to insure that the signal is not switched or disrupted.
To Protect an Output
The operator presses PROTECT. The system will request verification. (See Figure 6−10.) Press TAKE.
