Page of 102
This equipment has been tested and found 
to comply with the limits for a Class B 
digital device, pursuant to Part 15 of the 
Rules. These limits are designed to provide 
reasonable protection against harmful 
interference in a residential installation. 
This equipment generates, uses, and can 
radiate radio frequency energy and, if not 
installed and used in accordance with the 
instructions, may cause harmful 
interference to radio communications. 
However, there is no guarantee that 
interference will not occur in a particular 
installation. If this equipment does cause 
harmful interference to radio or television 
reception, which can be determined by 
turning the equipment off and on, the user 
is encouraged to try to correct the 
interference by one or more of the 
following measures:
Reorient or relocate the receiving 
antenna.
Increase the separation between the 
equipment and the receiver.
Connect the equipment into an outlet 
on a circuit different from that to 
which the receiver is connected.
Consult the dealer or an experienced 
radio/TV technician for help. 
You are cautioned that any changes or 
modifications not expressly approved in 
this manual could void your authority to 
operate this equipment. 
Only peripherals (computer input/output 
devices, terminals, printers, etc.) that 
comply with FCC Class B limits may be 
attached to this computer product. 
Operation with non-compliant peripherals 
is likely to result in interference to radio 
and television reception.
All cables used to connect peripherals must 
be shielded and grounded. Operation with 
cables, connected to peripherals, that are 
not shielded and grounded, may result in 
interference to radio and television 
reception.
FCC Part 68
This equipment complies with Part 68 of 
the FCC rules. On the bottom of this 
equipment is a label that contains, among 
other information, the FCC equivalence 
number (REN) for this equipment. If 
requested, this information must be 
provided to the telephone company.
This modem uses the USOC RJ-11 
telephone jack.
The REN is used to determine the quantity 
of devices which may be connected to the 
telephone line. Excessive RENs on the 
telephone line may result in the devices not 
ringing in response to an incoming call. In 
most, but not all areas, the sum of the RENs 
should not exceed five (5.0). To be certain 
of the number of devices that may be 
connected to the line, as determined by the 
total RENs, contact the telephone company 
to determine the maximum REN for the 
calling area.
If the terminal equipment (Notebook 
Computer PCG-F250/PCG-F270/
PCG-F280/PCG-F290) causes harm to the 
telephone network, the telephone company 
will notify you in advance that temporary 
discontinuance of service may be required. 
But if advance notice is not practical, the 
telephone company will notify the 
customer as soon as possible. Also, you 
will be advised of your right to file a 
complaint with the FCC if you believe it is 
necessary.
The telephone company may make 
changes in its facilities, equipment, 
operations or procedures that could affect 
the operations of the equipment. If this 
happens, the telephone company will 
provide advance notice in order for you to 
make the necessary modifications in order 
to maintain uninterrupted service.
