Troubleshooting
If the image does not appear or there is no sound
1.
Ensure that all devices are plugged in to a power source.
2.
Make sure that each device is receiving power.
If the switcher is in manual switch mode, one of the input
indicator LEDs should light on the front panel of the
SW2 VGA DA2 A /AF. If the switcher is in autoswitching
mode and there is no active incoming sync signal detected,
the input indicator LEDs will not light. However, the
autoswitching indicator LED should light when the
autoswitching mode is on. If no LED lights, check to make
sure the power connector is properly wired and neither
conductor is connected to the middle pole.
3.
Check the cabling and the audio connector wiring, and
make adjustments as needed.
4.
Select a different input to check for a display and sound.

Make sure that all the input and output devices and the
switcher are powered on.
