3. Wiring precautions:
• Do not bend the coaxial cable into a curve whose
radius is smaller than 10 times the cable’s diame-
ter.
• Never staple the cable even if with circular sta-
ples. Impedance mismatching will occur.
• Never crush or pinch the cable.
All of the above will change the impedance of the
cable and cause poor picture quality.
