The D3x camera models have three (3) designs. Check your camera design to know the 
suitable step in removing the front cover. 
Design #1 
Plain Front Cover 
Design #2 
Front Cover with Sticker 
Design #3 
Front Cover with Tabs 
Detach the front cover using an 
adhesive tape or a suction cup 
(not included in the package). 
Pull the plastic tab to detach the 
front cover. 
Using pliers, pull by the tabs to 
detach the front cover. 
NOTE: For D3x cameras with Design #2, remove the whole sticker from the front cover after 
adjusting the focus. The sticker cannot be reattached to the front cover. If the focus needs to 
be adjusted in the future, use a suction cup or adhesive tape to detach the front cover.
