Remove the C445B... Option Cover as shown in Figure 16.
The Option Cover may be discarded as it will not be reinstalled.

into the C445B... communications card pocket until the card is completely seated and the
locking tab snaps into place.
Figure 19. Component Mating
The C445B... Base Module can be attached to the top of the C445MA...
Measurement module.
Orient both modules so the two (2) RJ12 jacks on the C445B... module are on the same
side as the RJ12 jack on the C445MA... module.
Align the modules so there is an offset of 0.098–0.157 in (2.3–4.0 mm).
Slide the C445B... Base Module downward on the C445MA... Measurement Module until
the locking tab moves into place.
