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:
l
Reorient or relocate the receiving antenna
l
Increase the separation between the equipment and receiver
l
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
l
Consult the dealer or an experienced radio/TV technician for help.

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.
