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
back-
ing is quite rigid, but the soldering and electronic components
attached to the card are very delicate. Dropping the card or hit-
ting 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.
