I cannot be certain as I don't have that model, but usually the external connections are listed as AV1, AV2 etc. So if you select BBC1 and then select "channel -" (i.e press the channel up or down button "down" ) you should see the AV (audio / video) inputs. The scarts are normally AV1 and AV2 with the discrete phono connectors AV3 or AV4. Plug the camera in, start playing a tape and then play with the channel up/ down button until you see the picture. Sorry I cannot be more precise.
I do suggest you refer to the manual. You should be able to download it if you, like me, can never find the bloody thing when you need it!
