TheprogrammingofIRcode：
Thereare>10typesofDVD,NAVI,andTuners’IRcodearestoredinsidetheinterface.Theinstallerjustadjuststheoptionstoselectto
wantedone,thenitworks.Ifthewantedtypeisnotthere,hemaysettheoptiontobe“Prog”inthemenu.
Whenprogramming,switchtheinputtoAV1,andsetDIP6downonce,thenthecontroliconswillbeshown,andoneofthethemwill
beblinking.PointtheIRremotecontrollertotheIRportofinterface,theblinkingiconwillbemovedtothenextone.Whichmeans
onecodeisprogrammed.Repeatthisstepuntilalliconsareprogrammed.
