I'm going to extend my Clarity station. Do I need to change my HW key?

Most probably you need an appropriate User Code (u/c) only. HW key keeps basic serial number XX-YYYYY (event. XX-YYYYYY) only and all information about valid version, number of instruments, extensions and control modules are part of the User Code.

Only when upgrading from Clarity Offline to Clarity or Clarity Lite it is necessary to replace the HW key with a new one.
