Zoom ring unit
① Mount the zoom ring unit on the SWM, and fix with the
four screws (#140).
(For this mounting, refer to the positional relationship
between "Index" and "MR head" in "Fig. 1".)
Caution:
Whenever the zoom ring unit is mounted,
do NOT touch the MR head.
If pressure is put on
the MR head from
outside, the position is
misaligned, resulting in
a change of accuracy.
② After attaching a distance-scale sticker on the SWM, attach two pieces of the tape [TA-0012 (3mm×12mm].
  (The distance-scale sticker has the adhesive double-coated tape attached.)
