FEDERAL COMMUNICATIONS COMMISSION AND

CANADIAN DEPARTMENT OF COMMUNICATIONS

RADIO FREQUENCY INTERFERENCE STATEMENT

Class B Digital Device. This equipment has been tested and found to comply with the limits for a

Class B computing device pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference in a residential installation. However, there is no

guarantee that interference will not occur in a particular 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. If this equipment does cause

harmful interference to radio or telephone reception, which can be determined by turning the

equipment off and on, the user is encouraged to try to correct the interference by one 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 an experienced radio/TV technician for help.

Caution:

Changes or modifications not expressly approved by the party responsible for

compliance could void the user’s authority to operate the equipment.

To meet FCC requirements, shielded cables and power cords are required to connect this device to a

personal computer or other Class B certified device.

This digital apparatus does not exceed the Class B limits for radio noise emission from digital

apparatus set out in the Radio Interference Regulation of the Canadian Department of

Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables

aux appareils numériques de la classe B prescrites dans le Règlement sur le brouillage radioélectrique

publié par le ministère des Communications du Canada.

instructivo de operación, o como se indique en el aparato.

12. Precaución debe ser tomada de tal manera que la tierra fisica y la polarización del equipo no

sea eliminada.

13. Los cables de la fuente de poder deben ser guiados de tal manera que no sean pisados ni

pellizcados por objetos colocados sobre o contra ellos, poniendo particular atención a los

contactos y receptáculos donde salen del aparato.

14. El equipo eléctrico debe ser limpiado únicamente de acuerdo a las recomendaciones del

fabricante.

15. En caso de existir, una antena externa deberá ser localizada lejos de las lineas de energia.

16. El cable de corriente deberá ser desconectado del cuando el equipo no sea usado por un largo

periodo de tiempo.

17. Cuidado debe ser tomado de tal manera que objectos liquidos no sean derramados sobre la

cubierta u orificios de ventilación.

18. Servicio por personal calificado deberá ser provisto cuando:

A: El cable de poder o el contacto ha sido dañado; u

B: Objectos han caído o líquido ha sido derramado dentro del aparato; o

C: El aparato ha sido expuesto a la lluvia; o

D: El aparato parece no operar normalmente o muestra un cambio en su desempeño;o

E: El aparato ha sido tirado o su cubierta ha sido dañada.
