Refrigerator setting.... help!
From the manual:


  The control wheel on the front of the worktop adjusts the inter
  nal fridge compartment temperature.  The internal temperature should be 5 °C 
  or colder although some sections, such as the salad bin, will be slightly w
  armer.
  The setting of the control wheel will depend on the location of
   the fridge, the room
  temperature and how often the door is opened.  The normal set point (marked by a 3
  and N on the dial) is usually suitable.


(emphasis mine)

Of course, the best way to find out is to put a themometer inside and check if it indicates 5 °C.
