the DIP switch to pin 1 at OFF (), pin 2 at ON () for safe mode to enforce 1080p stereo output
for system check. However, the safe mode cannot be initiated if your HDMI sources are set to
enforce output at fixed resolution. In this case, please reconfigure your HDMI source to all
resolutions output for troubleshooting.

Bypass means this device will maintain playing the original format of HDMI signals in video and
perhaps audio. By setting at this mode, the users may encounter compatibility issue among
different kinds of HDMI sources and displays. If you cannot get the audio and/or video output
normally at the system installation, please change the DIP switch setting to default mode or even
safe mode to verify the functionality of the device.
