Using the modem feature
You can use the ThinkPad 570's built-in modem function in a particular country only if IBM has
received approval from the proper authorities in that country. If IBM is not authorized, a
question mark (?) appears to notify you that the modem function is disabled.
You can check the up-to-date listing of countries on the IBM Web site
(http://www.pc.ibm.com/support). The listing is updated when the approval of a country is
received.
To use the modem function in a country where it is authorized, go to the same Web site,
select Notebooks and PC companions from the menu, and download the device and
software.
