bush tv (old)?

the remote control for my bush tv has been lost and i have been informed a replacement is not available. since moving i am now on a different tv station and can find no way to tune the set in manualy. is it possible to do this if so how? the only buttons on the set are p+, v+, v-.any helpwelcome.the only ident on the tv is bush internet which is on the front.
