5. Refer to the 46-120 main PCB layout diagram above. Note that there are several jumpers on the PCB which will be not
readily accessible once the CDI-46 card is installed (i.e., the card will need to be removed to access them). Therefore
installers should ensure that these jumpers are set as required BEFORE fitting the CDI-46.
Note that J10 to J13 MUST be removed for the CDI-46’s Digital Paging Interface to operate correctly. If the CDI-46 is being
installed purely for remote control purposes (and not paging), they can stay in place.
