Federal Communications Commission (FCC) Statement
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated
in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own
expense.
Properly shielded and grounded cables and connectors must be used in order to meet FCC emission limits. IBM is not responsible
for any radio or television interference caused by using other than recommended cables and connectors or by unauthorized changes
or modifications to this equipment. Unauthorized changes or modifications could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
In addition to the above FCC statement, you should be aware that:
The statement applies only to IBM 3745-130/150/170 Communication Controllers used in the USA and
having a label on the back that indicates compliance.
