(2) For AV1 and AV2, S-Video has priority. If a signal is connected to AV1 S-Video by itself
or signals are connected to AV1 S-Video and AV1 Video simultaneously, then S-Video
will be the only choice for AV1. If a signal is connected to AV1 Video only, then Video
will be the only choice for AV1. The same input priority scheme applies to AV2.
*** When Speakers off
**** Do Scan or Manual Scan function, it maybe spend several minutes is normal. It
depends on channels and area.
