2-2-1. 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 two circled portions (1, 2)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

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.

2-2-4. ADHERE THE ORNAMENTAL RING A
Apply an adhesive tape to two recesses on the top surface of the Barrier Assy.
Meeting a “notch” of the Ornamental Ring A with a “projection” of the group-1 frame, push the Ornamental Ring A into the group-1 frame.
* The projection of the spring for preventing static electricity must be tilted.
* The projection of the spring for preventing static electricity must be tilted.
Put the 60g weight on the Ornamental Ring A so that the Ornamental Ring A does not float up until the adhesive hardens.
Note: Be careful not to give a shock.
* After the weight was put, no gap must be present in full circumference between Ornamental Ring A and group-1 frame.
Note: Be careful not to give a shock.
* After the weight was put, no gap must be present in full circumference between Ornamental Ring A and group-1 frame.
A gap, if present, causes the crackle sound NG.
* The weight must push in the Ornamental Ring A only.
If the weight is put on the mold part of the Barrier Assy, the Ornamental Ring A will float up.
Completion after 30 minutes.
