Figure 5.5 Sealing Ridge on Expansion Back Cover
Back cover modules are attached to the Omnii main housing with eight T10 Torx screws that enter
from the back, plus two T6 Torx screws that enter through the front of the unit above the display,
and fit into inserts mounted in the inside of the back cover module. Any back cover module
you design must have these eight screw holes and two inserts to secure the back cover to the
main housing.
