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.
