How to tune a telly without remote/instructions?

I have been given a daewoo tv combi model number GB14F7TI portable tv with no remote - my universal control switches the tv on - it displays emergency in the top left corner and bb1 etc on the right corner - i only have a blue screen - no idea how to tune it in or how to get the video tape out as eject doesnt seem to work - any ideas greatly appreciated?
