Using the QR Code with the Mobile Quiver Navigator App. 

The mobile Quiver Navigator App has been updated to utilize a QR code that 

contains the details of CPD or Return Loss faults.  The Quiver XT includes Passive test 
CPD and NTC TDR responses you can use to test this feature.  To access the test 
feature use the soft keys and buttons to navigate to “SETTING” and then “4.QR code 
test”.  Now your presented with two test options.  “NTC TDR” will be illustrated in this 
example:
