Configuration
Only trained personnel are permitted to make changes to the device
configuration.
To individually configure an instrument with standard configuration, the
instrument must be connected to a PC via the USB infrared cable (order no.
83 17 409) or the E-Cal system. 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 5600 at the
following Internet address: www.draeger.com.
 Change configuration: see Technical Manual.
