the instrument must be connected to a PC via the USB infrared cable
(order no. 83 17 409). Dräger CC-Vision PC software is used to
perform the configuration. The Dräger CC Vision PC software can be
downloaded free of charge from the product page of the X-am 2500 at
the following Internet address: www.draeger.com.
