thread is screwed onto the connecting screw thread. Tighten the
nut until it is stops.

CAUTION
• If you cannot mount or remove the optical adapter because the nut will not turn, stop using it
and contact Olympus.
• The optical adapter is a precise instrument using glass components in the optical system. Do
not drop it or hit it against hard surfaces.
NOTE
• The optical adapter is designed for safety with a double-screw construction to prevent it from
falling off.
