It's been fully serviced, which means thus cube-like player is ready for you to play your choice of radio station via the glass-topped receiver. Alternatively, push the upper level to the side to gain access to the Dual record deck below, with volume and tone controls on that higher level, should either need adjusting.
As we said, full serviced, although the condition is described as 'very good used cosmetic condition', which perhaps isn't bad for 40 or so years on.
The downside is the price. £1,799 is the 'Buy It Now' figure, although you can make a cheaper offer if you wish.
