FEDERAL COMMUNICATIONS COMMISSION WARNING
This device complies with Part 15 of the FCC Rules and Regulations. Operation is
subject to the following two conditions:
This device may not cause harmful interference, and
This device must withstand any interference received, including interference that may
cause undesired operation.
The CBX 500 has been tested and found to comply with the limits for a Class A digital
device pursuant to Part 15 of the FCC Rules and Regulations. These limits are
designed to provide reasonable protection against harmful interference when this
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 and television
communications. Operation of this equipment in a residential area is likely to cause
interference in which case the user will be required to correct the interference at his or
her own expense.
Shielded cables must be used with this unit to ensure compliance with the FCC Class
Alimits.
Do not attempt to repair or modify this equipment. Any repairs to the unit must be
performed by Lucent Technologies or a Lucent-authorized representative.

If Problems Arise
If any of your telephone equipment is not operating properly, you should immediately
remove it from your telephone line, as it may cause harm to the telephone network. If
the telephone company notes a problem, they may temporarily discontinue service.
When practical, they notify you in advance of this disconnection. If advance notice is
not feasible, you will be notified as soon as possible. When you are notified, you will
be given the opportunity to correct the problem and informed of your right to file a
complaint with the FCC.
In the event that repairs are ever needed on this equipment, they should be performed
by Lucent Technologies or an authorized Lucent representative. For information
contact the Lucent TAC at 1-866-LUCENT8 (in the U.S.). For international telephone
numbers see “Technical Support” in “About This Guide.”
