I've never tried to use the dab side

This radio was bought for me but I don't listen to radios, hence I didn't use it. I turned it on when I first got it but never tried the dab side..
It was bought new and it came in the box and the the power lead was with it, but I've no idea what happened to either the box or the power lead, I don't have it so it's not included in the sale.

It will be sent tracked and insured 
Below is a copy of the Roberts website about the radio, but as stated, I can't say whether the DAB works
