Installing and Removing Plug-In Cards
The two slots for installing plug-in cards are designated Card Slot 1
and Card Slot 2. Card Slot 1 is closest to the front of the calculator-
Card Slot 2 is closest to the back. These slots are not identical. See
page 28-2 for details about the differences.
CSiUtion
Nonapproved plug-in cards and accessories may
cause damage to the HP 48. You can distinguish
a potentially damaging card or plug-in accessory
from an HP-approved card by looking at the back
side of the card where it plugs into the HP 48. An
approved card has a metal shutter to protect the
HP 48 from static charges. The nonapproved cards
and accessories examined to date by HP do not have
this shutter, but have exposed gold contacts instead.
