There is no barcode on the QIAsymphony cooling adapter, and the instrument asks for one. What do you suggest I do?

The barcode on the adapter at the cooling elution position is read by default. This can be changed in the configuration settings which are available from the tools menu if you have logged in as Supervisor. The option is on the tab Process SP1 and is called ”On which elution slots should the bar codes be scanned”. To disable the barcode reading, put the setting to ”none”.
