The following instructions detail how to remove a quad modem card and toggle its appropriate DIP switch section (on DIP switch S1) to assure that all remaining modem cards will be recognized by the Remote Annex 6300. Figure D-5 and Figure D-6 illustrate the instructions. These instructions assume that the cover of the unit has already been removed.

1Locate the quad modem card that you want to remove.

2Starting at one corner of the card, push in the locking detent on the nylon standoff, and gently work the corner of the card off the nylon standoff (see Figure D-5).

3Repeat the procedure for the other three corners of the modem card.
