Early versions of Discovery Ci and Wi systems used detector assembly 010-1653. This
assembly is no longer available and has been replaced by detector assembly ASY-00271.
The following procedure explains how to remove the old detector assembly and replace it
with the new detector assembly. If your system already has the new ASY-00271 detector
assembly, use the removal/replacement procedure in Section 5.7.1.
