Notes:
* Your TV’s audio settings may be set to “Variable”
or “Fixed”. We recommend that you set your audio
settings to “Fixed” for better audio quality when
using this installation option. If you want to be able
to control your TV volume level separate from your
SIMOLIO SM-621 volume level, you will need to
make sure your TV is set to “Fixed”. Contact your
TV manufacturer for assistance.
* Setting menu may be different depending on different TV brands and models.
