FCC COMPLIANCE STATEMENT FOR AMERICAN USERS

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 or

television reception. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause interference to radio and 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.

WARNING

The connection of a non-shielded equipment interface cable to this equipment will

invalidate the FCC Certification of this device and may cause interference levels which

exceed the limits established by the FCC for this equipment. It is the responsibility of the

user to obtain and use a shielded equipment interface cable with this device. If this

equipment has more than one interface connector, do not leave cables connected to unused

interfaces.

Changes or modifications not expressly approved by Epson America, Inc., could void the

user’s authority to operate the equipment.

FOR CANADIAN USERS

digital apparatus as set out in the radio interference regulations of the Canadian

Department of Communications.
