Guralp Systems CMG-DCM build <10,000 - Manual (Page 176)

CMG-EAM (Platinum Firmware)
The final section of the screen deals with the gimbal-mounted sensors
deployed in ocean-bottom systems, which need control of their
levelling and orientation functions. Where triaxial systems are
mounted in a single bowl, the Bowl drop-down-menu should be left at
“Single bowl”. Where separate bowls are used for each component,
the relevant component should first be selected from the menu.
