1.Ensure that all devices are plugged in.

2.Make sure that each device is receiving power. If the switcher does not power on, and the AC power source is functioning correctly, the AC fuse may be blown. (See “Replacing the AC fuse” on page B-3.)

3.Check the cabling, wiring, and grounding, and make adjustments as needed. Ensure that the selected output rate and sync format are appropriate for the output devices. (See page 3-6.)

4.To test the system setup and output, Display a test pattern. (See “Selecting a test pattern” on page 3-7.)

5.Confirm that the input is providing a signal with a horizontal frequency between 15 kHz to 100 kHz and a vertical frequency between 50 Hz and 120 Hz.

6.Call Extron’s customer support hotline if needed. Be prepared to discuss the steps you have taken and the equipment involved.
