Internal Modem Compliancy
The Notebook PC with internal modem model complies with
JATE (Japan), FCC (US, Canada, Korea, Taiwan), and CTR21. The
internal modem has been approved in accordance with Council
Decision 98/482/EC for pan-European single terminal connection
to the public switched telephone network (PSTN). However due
to differences between the individual PSTNs provided in different
countries, the approval does not, of itself, give an unconditional
assurance of successful operation on every PSTN network
termination point. In the event of problems you should contact your
equipment supplier in the first instance.
