Tip

:

When shooting underwater, a common practice to set manual focus is to use 

auto focus first.  In auto focus mode, point the camera at the subject or an object of 
equal distance from you, let the camera focus, then flip into manual.  This will ‘freeze’ the 
focus distance at that point.  

Manual  Focus 

This control is found on the left front of the housing and rotates the focus ring on the 
camera.  Note that the camera must be in manual focus mode, as actuated by the 
previous control.   

Gain  / White Balance Presets 

The Gain switch can be moved through all three positions (L-M-H).  Pull out and rotate 
the control 180° to reach the White Balance Presets A, B and Preset.

Caution

:

  Use care when mating the control with the toggle switch on the camera. 

The control head must cup the toggle switch in order to move it amongst the three  
positions.
