Hi and welcome to Beoworld! The Century may be in A.OPT 0, where it will not respond to IR commands. To resolve this: Turn to standby/off. On the Beo4, press the POWER button and LIST together. Then press LIST until OPTION is shown, press GO (centre button), and then press LIST to show A.OPT. Then press 1. The power light on the Century may blink to show that it has been accepted. (EDIT: The digit '1' should briefly be shown on the Century's display) Remote control should then work. If the above procedure does not work, check that the Beo4 is actually transmitting IR signals by viewing the end of the remote with a mobile phone camera (selfie camera if iPhone). You should see the IR transmitters glowing when buttons are pressed.

And if that doesn't work, you may need this for repairs: https://www.beoparts-shop.com/product/beosound-century-ir-remote-control-pcb-service-kit/ Martin

Thanks so much Guy, do you mean do this on the remote or the stereo itself as I tried it and it still doesn't work, I checked the IR an that works ok. Thanks for all your help

Thanks but the remote seems to be working with the camera test, am I correct in saying that the BEO 4 is the right remote for the Century ?
