RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency energy and if not

installed and used properly, that is, in strict accordance with the manufacturer’s

instructions, may cause interference to radio communication. It has been tested

and found to comply with the limits for a Class A computing device in accordance

with the specifications in Subpart J of Part 15 of FCC rules, which are designed to

provide reasonable protection against such interference when the equipment is

operated in a commercial environment. Operation of this equipment in a

residential area is likely to cause interference, in which case the user at his own

expense will be required to take whatever measures may be necessary to correct the

interference.

Changes or modifications not expressly approved by the party responsible for

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

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

apparatus set out in the Radio Interference Regulation of Industry Canada.

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

applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le

brouillage radioélectrique publié par Industrie Canada.

The Fiber Link complies with CE EN55022 and EN50082-1 requirements.

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
