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.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC 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 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.
Important
A shielded interface cable should be used to ensure compliance with the limits for a Class B
digital device. Changes or modifications not expressly approved by Brother Industries, Ltd.
could void the user's authority to operate the equipment.

This machine is certified as a Class 1 laser product under the U.S. Department of Health and
Human Services (DHHS) Radiation Performance Standard according to the Radiation
Control for Health and Safety Act of 1968. This means that the machine does not produce
hazardous laser radiation.
Since radiation emitted inside the machine is completely confined within protective housings
and external covers, the laser beam cannot escape from the machine during any phase of
user operation.
■ FDA Regulations (110 to 120 volt model only)
The U.S. Food and Drug Administration (FDA) has implemented regulations for laser
products manufactured on and after August 2, 1976. Compliance is mandatory for products
marketed in the United States. The following label on the back of the machine indicates
compliance with the FDA regulations and must be attached to laser products marketed in the
United States.
