At this point, do not x the detector head.
(Screws and washers, etc. to be used)

NOTICE
The head xing blocks that x the detector head dene the positional relationship between the scale main unit
and the detector head.
When mounting the scale unit on the machine, do not remove the head xing blocks in order to keep the posi-
tional relationship.
