Section 4: Swapping Sensors; Drs Models - QVI Cobra DRS-300 User Manual

Section 4
One unique feature of Cobra is that you can quickly and easily replace one
sensor model with another to accommodate your specific application. This
section provides information on the different DRS models available and how to
swap one sensor for another.
Note: The procedure for swapping laser sensors varies, depending on the
configuration of your Cobra. The procedure for changing sensors on Cobra
systems equipped with the video camera option starts on the following page and
the procedure for changing sensors on Cobra systems not equipped with the
video camera option starts on page 4-8. Be sure to follow the procedure that
applies to your system.
