Beko LF320 temperature dial numbered 1 to 10 which...

Question

We have a Beko LF320 refridgerator that came with our apartment and it has a dial numbered 1 to 10 to set the temperature. It's set at number 5 but keeps freezing our vegetables. 
But which way to turn the dial to make the temperature slightly warmer? Is 10 coldest or hottest? 
I don't want to freeze the contents of my fridge nor do I want to keep everything at a too warm temperature.
