Mounting Instructions for the
HDNS-2100 Lens to the Base Plate
An IGES format drawing file with
design specifications for mouse
base plate features is available.
These features are useful in
maintaining proper positioning
and alignment of the HDNS-2100
when used with the Agilent
Optical Mouse Sensor. This file
can be obtained by contacting
your local sales representative.
