Use and change of the Color Correction Filter 

The internal color correction filter is specially designed by UR 
Pro to correct for color loss underwater.  A “blue water” version 
(orange in color) is provided standard with the EX1R housing, 
however a “green water” version (pink in color) is available as 
an option.

Changing the filter

 is accomplished by loosening the 

screw on the filter holder closest to the filter element using 
a 7/64” hex tool.  Remove the filter element gently while 
stabilizing the filter holder.  Reverse this process to install 
new filter element.

Cleaning

.  You will likely have fingerprints on the filter after 

installing, so clean the filter according to the directions in 
the “Cleaning Ports and Filters” section.   

Use and change of the Flip Diopter 

The flip diopter allows convenient close up/macro imaging with a simple ‘flip’ of the 
diopter element in front of the camera.  If this option is installed  you can change the 
diopter amongst the +1, +2 and +4 strengths provided with your kit and used with the 
FP44 flat port.

Changing the diopter

 is nearly identical to the process for changing a filter (see 

photo above).  Loosen the screw on the diopter holder closest to the diopter element 
using a 7/64” hex tool.  Remove the diopter element gently while stabilizing the 
holder arm.  

9

Installing a diopter 

is the reverse, however the diopter must be oriented with the 

‘flat’ side closest to the camera and the convex side toward the port.   

9

Cleaning

.  Again, you will likely have fingerprints on the diopter after installing, so 

clean the filter according to the directions in the “Cleaning Ports and Filters” section.

Tip

:

The flip diopter is designed for macro imaging with the camera partially or fully 

zoomed to telephoto.  At full wide angle you may see vignetting (cut off corners).  

This is 

normal.  

Use of other diopters 

The EX1R housing can accommodate the use of diopters affixed to the camera body in 
conjunction with the FP44 flat port.  Depending on the manufacturer the diopters may be 
stacked.  Note that the color correction filter cannot be used in this configuration.   
 

Change the filter by 
loosening this screw 
with the 7/64 hex tool.
