    In some cases it may be useful to take pictures of the damage to present to the carrier if a claim must be made. As the SC-4 is unpacked for installation, carefully check for any internal damage. Exam- ine the frame and contents carefully as rough handling may dislodge cards and/or power supplies and cause internal damages not readily noticeable until the equipment is pow- ered up.

    Overview The Critical Issue The SC-4 uses an analog signal (black burst or tri-level) as reference for vertical interval switching. If single sync is used (i.e., black burst), the following should be noted: Within NTSC configurations, the system is attempting to switch on line 10 of reference, yet within HD/SD environments, the switching of HD signals should occur at line 7.
