5. NOTES
On the oCam-2WRS-U, you can adjust the focus by rotating the lens by hand. Therefore, in a
vibrating environment, the lens can be loosened by being rotated by itself. To prevent this, it is
recommended to lock the lens by using the supplied lens lock ring after you finish adjusting the
focus.
To change the lens, you need to loosen the lock ring first before you take out the lens from the
holder.
