To install the TDi, proceed as follows:

1.  Determine on which corner of the scanner you want to install 

the TDi. It can be placed in either the left or right-hand corner 
just behind the scanner’s bonnet. Carefully push upwards on 
the plastic Corner Piece to disengage it from the scanner.

2.  Gently slide the Filler Tab from the Corner Piece. This will leave 

an opening for the neck of the TDi.

down through the base 
of the scanner, gently 
pulling them all the way 
through on the bulkhead 
side of the base and sea-
ting the TDi in its corner 
cavity. Make sure they 
are not pinched or cau-
ght beneath the scanner 
base.
