If your remote hasn't got a TV/AV button on it the symbol for the AV channel(s) button is a square with an arrow going in one side, press this once to get AV1 & twice to get AV2 (you will only get AV2 if your TV has got 2 SCART sockets in the rear. You might also get AV3 but ignore that that is for equipment that uses 3 phono jacks (Red,White & Yellow)
