Before Disassembly / Assembly / Adjustment ...
Note:
① When disassembling, make sure to memorize the processing state of wires and FPC.
②Because prototypes are used for "Disassembly/(Re)assembly/Adjustment", they may differ from the actual
products in forms, etc.
③ Because pictures are processed by a special method, they may differ from the actual ones in texture.
・Lead-free solder is used for this product.
・For soldering work, the special solder and soldering iron are required.
・Do NOT mix up lead-free solder with traditional solder.
・Use the special soldering iron respectively for lead-free solder and lead solder.
They cannot be used in common.

② Attach 3 1st lens-G collars (#6) and 3 screws (#7) to the 1st lens-G sliding ring.
③ Set the straight tube of the lens body to WIDE side.
④ Viewed from the 1st lens group side, place the “PC-30” letters of the focus ring at the position of 10 o'clock,
by counting the index position of the 1st lens-G sliding ring as 12 o'clock.
⑤ Put the focus ring and 1st lens-G sliding ring in the place of Fig.1. Then align the convex portion of the lens
body with the concave portion of the focus ring to assemble them.
⑥ Turn the lens body, which was assembled in ⑤ in the direction of the arrow until its convex portion enters in
the inner groove of the 1st lens-G sliding ring. Then push the lens body and focus ring all the way into the
1st lens-G sliding ring.

・How to inspect and adjust:
① Conrm that the electric current and voltage of the connected rated voltage power-supply are set values, then
turn it ON.
② Set the oscilloscope, and turn the focus ring manually.
Note: The waveform varies according to the rotational speed of the focus ring. So change "Time/Div” setting
accordingly.
