Plug the interface module on the right side of the PC board (see picture 3). The cables are to be fed through the
rightmost cable feedthroughs into the calculator after removing the blind grommets. Close the calculator.
Protect the calculator against unauthorized opening using one of the numbered adhesive seals enclosed to the
modules (stick it upon the seal destroyed). The added bar code label can be used for the purpose of
documentation.
To remove a module the upper housing piece must be carefully pressed against the rear panel of the lower housing
piece during opening the calculator. Thus the two rear snap-fits of the upper housing piece lever out the module of
the PC board (see picture 4).
