1. Replacing the Nylon Ring
The WRR-855B is attached to a Camcorder or its adapter using four screws (+P2.6x10) on the front panel assembly.
The nylon rings must therefore be attached to the correct position so that the these screws have the same length.
How to attach the nylon rings
1 Push in a nylon ring to the deepest end using tweezers.
2 Use a flat plane to align the tips of the screws with the front panel.
