2Mounting the PPO-E04 on the Underwater Case

This chapter describes how to mount this product and an applicable lens on the PT-E series Underwater
Case. Before mounting, make sure that no foreign matter is attached to the PPO-E04’s O-ring and thread-
ed section or to the case’s port mount thread and O-ring contact surface. Apply a thin layer of the provided
silicone O-ring grease to each of these parts.
Align the threaded section of the PPO-E04 with the port mount thread on the PT-E series case.
Hold the PT-E series case firmly with one hand, hold the lens hood around the lens of the PPO-E04 with
your other hand and screw it into the PT-E series by turning the PPO-E04 clockwise.
Resistance increases as the PPO-E04 is screwed in more deeply. However, be sure to screw it in all the way
until there is no gap visible between the case’s port mount thread and the PPO-E04’s threaded section. If the
resistance is extremely high, apply some more silicone O-ring grease again to surfaces listed above.
