䊳 Uninstall the existing driver
䊳 Install the Windows XP driver from the PCS Connection
Card installation CD.
Uninstalling the Existing Driver
1. Open the Control Panel by selecting Start > Control Panel.
2. If “Pick a category” is displayed, select Switch to Classic
View.
3. Double click the System icon.
4. Click the Hardware tab.
5. Click the Device Manager button.
6. Locate the PCS Connection Card entries by using the “+”
signs to expand the listings. (For example, to see all the
installed modems, click the “+” sign to the left of
Modems.) The card should have 3 entries:
䊳 The card should display under Multifunction adapters as
Sierra Wireless AirCard 550 PC Card Parent.
䊳 The card should display under Modems as Sierra
Wireless AirCard 550 Modem.
䊳 The card should display under Network adapters as
Sierra Wireless AirCard 550 Adapter.
If the listings above do not appear, identify the listing for
the PCS Connection Card by ejecting the card. This causes
the driver listing for the card to disappear from the list.
Reinsert the card again to cause the driver listing to reap-
pear. You can identify the entries for the PCS Connection
Card by observing which entries are affected when you
eject and reinsert the card. Right click Sierra Wireless Air-
Card 550 PC Card Parent (or the PCS Connection Card listing
under Multifunction adapters) to display a pop-up menu.
7. Select Uninstall in the pop-up menu.
8. Confirm that you want to uninstall the device by clicking
OK.
The PCS Connection Card listings should be removed.
