Connecting Shelves
For the 2-shelf system, you need to install an optional BUS-M card in the Basic Shelf. To connect the
shelves, plug the Bus Cable (supplied with the BUS-M card) into the bottom slot of the BUS-M card. Then,
plug the other end into the BUS-S card built in to Expansion Shelf 1.
For details about the cards, refer to "2.4.1 BUS-M Card (KX-TDA6110)" and "2.5.1 BUS-S Card".
Note
When installing or removing the BUS-M card, make sure that the DC power supply is turned off.

Insert the BUS-M card along the guide rails in the BUS-M Card Slot (the right-most slot) of the Basic
Shelf.
2.
Push the release lever in the direction of the arrow so that the BUS-M card engages securely with the
connector on the back board.
