How can I subscribe Just Best Bid and Best Offer(Ask) Prices

It seems that when I try to subscribe via this message each action on order book sent to me. I'm getting delete messages also.

 {
      Symbol = 1;
      MDEntryID = 925029575;
      MDUpdateAction = DELETE (2);
    }

I just want to subscribe to the best bid - best ask. Which part of the message that I must change?
