Connection

CONNECTION & OPERATION

Step1:ConnecttheHDMIcablesfromtheHDsourcesdevicestotheinputportsoftheSwitcher. Step2:ConnecttheHDMIcablefromyourHDTV(orprojector)totheoutputportoftheSwitcher. Step3:ConnecttheDC5V/2ApoweradaptortotheHDMISwitcher.

Step4:Afteryoufinishtheconnection,thepowerindicationLED(red),ARCindicationLED(blue), andport1inputindicationLED(green)willbelightedon.

Step5:InitiatetheCECcommunication:

(1)TurnontheconnectedTV,Switchbox,andallconnectedsourcedevices.

(2)Selectthesourcedevicesonebyone,andmakesureallsourcedevicesareworkingcorrectly. (AudioandvideocorrectlyshowonTVwithnointerruptionornoise.)

(3)Followtheoperationalinstructionbelow,andtryalltheoperationfunctionincludeCECcontrol function(RoutingChange,OneTouchplay,Standby.)

(4)If anyfunctioncannotwork,pleaserestarttheswitcherandperformStep5again.

Note:

1. Initiate the CEC communication can make sure the switcher collect the correct EDID informationfromsourcedeviceanddisplaydevice.IncorrectEDIDinformation maycause failureofCECfunction. (DuetovarieddesignofCECdevice, someCECdevices will automaticallyinitiatetheCECcommunicationwiththeswitcher.)

2. Thefollowingconditionsarerecommendedtoinitiateorre-initiatetheCECcommunication:

 WhenyoufirstusetheHDMISwitcherwithyourCECenableddevice.

 WhenyoudisconnectorchangethecableconnectionroutingoftheconnectedHDMI
