2.
Position the card in the open slot, making sure that the tabs on the both sides of the card fit into place.
Then, holding the card firmly in place, lower the rear end so that the holes of the card are aligned with
the screw holes.
3.
Insert the spacers (①) into the holes on the card, and tighten the spacers to secure the card.
Note
When using an LCOT4 card with a DPH2 card, install the LCOT4 card in the bottom.
4.
Connect cables to appropriate ports of the card. For details about pin assignments, refer to the appropri-
ate section in "3.5 Connecting Extensions" and "3.6 Connecting Doorphones and Door Openers".
Note
Make sure to connect cables after installing the card in the PBX, not before.
