seperating the unit
now this is really annoying so remain calm, you need to find two section like this:
now one side will have a small bit of plastic over it and the other wont on the inside to the vent push a screw up between the parts (the surround and a slight darker, piece that it connect to) try moving it round carefully prize-ing as you go, close to one of the vent push the screwdriver up, and do the small with a second jewellery screwdriver (flat head, not phillips) on the opposite side then place on the floor or desk with srewdriver on the table and the top of the vent looking up and whil hold the sides not the surround and making sure the vents are open push down forcing the surround off. but be very careful as it is plastic!
now you can remove that little piece of plastic, and you should be left with this,
plus the surround which isnt in the picture.
NOTE: THE PARTS INSIDE THE VENTS HAVE SOME SORT OF BLACK GREASE SO BE CAREFUL OF YOU CLOTHES AND FURNITURE.
