2-3-1. PEEL OFF OLD ORNAMENTAL RING A
The Ornamental Ring A has adhered to the Barrier Assy strongly and accordingly, use a soldering iron to weaken the adhesive force.
Heat four circled portions with the soldering iron.
Heating temperature is about 300ºC.
Beware of a burn since the entire Ornamental Ring becomes hot.
* As the adhesive force of Ornamental Ring A is considerably large, the forced peeling will damage the group-1 frame.
Insert the tip of tweezers, etc. into a notch of the group-1 frame and prize the ring.
* Take extreme care so as not to damage the coated surface of the group-1 frame.
In case of difficult peeling, heat the ring again with the soldering iron.
If this re-heating failed, it may be advisable that the ring be peeled while heating the portions 1
by one sequentially.
* Discard the removed Ornamental Ring A.

* After removing the Barrier Assy, if the "G1 Dust-Proof Ring" was removed, it must be returned to the home position.
In returning the ring, adjust the location of a projection to the lens direction.
This is an important part to prevent the dust and light from coming in.
* After removing the Barrier Assy, take extreme care not to drop dust or foreign substances in the lens barrel.
