2 Check and Cable Connection
For installation requirement of the decoder, refer to engineering construction specifications and
national standards.
HDMI cable quality and length affect the video quality. The video might blur, have noise or black
edge. Sometimes the video quality might vary when the same video is output with different
cables.
Unpacking the Box 2.1
When you receive the decoder, please check whether there is any visible damage or not. The
protective materials used for the package of the device can resist most accidental collisions during
transportation.
The label at the bottom of the box is very important, because there is serial number and other
information. Usually we need you to present the serial number when we provide after-sales service.
Do not tear or discard it.
