Selecting the Correct Slot

For most option cards, it makes no difference which slot they are installed in. Occasionally, however, a card may require a specific slot. Check the option card manual to determine if your option card requires a specific slot.

Some cards come with their own outlets. In a case such as this, the side with the outlet fits into one of the pop-out access slots on the back of the main unit. Slot 5 is fitted with a round pop- out access hole on the back of the main unit, while slots 1 through 4 have vertical pop-out slots. If the option card comes with a round outlet, you’ll probably want to install it in slot 5.

Unpacking and Handling the Option Card

Carefully remove the option card from its carton. (Save both the box and packing materials.) Hold the card only by its edges. The backing is quite rigid, but the soldering and electronic components attached to the card are very delicate. Dropping the card or hitting it against a hard surface may damage it. Touching any part of the card edge (which looks like a metal fringe on the bottom of the card) should also be avoided, because dirt or grease will impair proper contact with the QX-10.

Even though they are designed to fit only one way, it’s a good idea to examine the card first. The card edge should be pointing down and the components should be on the left side when you’re facing the back of the main unit. When the option card comes with its own outlet, the side with the outlet goes into the back of the main unit. The card edge fits into one of the five connector slots.
