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 di󱐯erences between the individual PSTNs provided in di󱐯erent 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 rst instance.
