Positioning Lex Air for use
Remove Lex Air from its protective drawstring bag and place it on a flat surface.
When doing so, try and ensure that it’s not directly underneath any bright
lighting, as this can affect its accuracy, especially when reading glossy documents.
Lex Air contrast/positioning mat
Lex Air also includes a contrast/positioning mat. This can be used if the surface
where you wish to place the Lex Air is very dark and the item wishing to be read
is small (e.g. a postage receipt, business card etc.).
If you wish to use the contrast mat during capture, simply place the Lex Air within
the precise cut out area of the mat. Please see “Positioning your documents for
capture” on page 8.
Place the camera
inside the cut out area
to use the mat as a
positioning guide
Velcro patch on the
up side of the mat, in
the rear right corner,
indicating this is the
correct side to be
facing upwards.
