TAKING CARE OF YOUR MACHINE
Do not locate your machine in an environment where it is susceptible to dust or moisture. Both of these
may damage the electronics, and cause erratic operation or failure. Do not locate your machine where
temperature and humidity may be excessive. Do not clean your machine with abrasives or strong cleaners.
Doing so may remove or damage the finish, or may allow moisture to build up. Take care not to allow dust
or particles to build up inside unused or open connectors.

TROUBLESHOOTING
10.1 Video Signal
Problem Remedy
No video at the output device,
regardless of input selected. 1. Confirm that your sources and output device are powered on and
connected properly.
2. Confirm that any other switchers in the signal path have the proper
input and/or output selected.
3. Use a Video Tester to test the video path leading to/from your
switcher (see section 4.1 " Video Tester")
Video level is too high or too
dim. 1. Verify that the video line is well matched through 75ohm
impedance; otherwise it results in a video level that is too high or
too dim.
2. Confirm that the connecting cables are of high quality, properly
built and terminated with 75ohm BNC connectors. Check level
controls located on your source input device or output display or
recorder.
