Interesting that the Honeywell document claims the Laseref VI is installed in the Challenger 605, while the FCOM states the Laseref V. It may be that the production standard was upgraded and the text about realignmnet conditions was changed, but the intro text wasn't. And unless the change was pre-production then there should be text covering both variants.
Ah, well, not the first error i've come across in an aircraft manual.
