Note: 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 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 the 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. To maintain compliance with FCC radio frequency emission limits, shielded cables are required to connect equipment to other Class B certified devices and the use of quadshield, RG-6/U type CATV cable is required for connection to the CATV system.

Any changes or modifications may void the user’s authority to operate this equipment.

Warning: Only devices certified to comply with the Class B limits pursuant to Subpart B of FCC Rules may be attached to this equipment. Operation with noncertified devices is likely to result in interference to radio and TV reception. Changes or modifications made to this equipment, not expressly approved by the

FCC could void the user's authority to operate the equipment.

This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the

Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de classe B prèscrite dans le

Règlement sur le brouillage radioélectrique édict par le Ministère des Communications du Canada.

Warning - The LCPET-xx is designed to work with single-phase power systems having a grounded neutral conductor. To reduce the risk of electrical shock, do not plug the LCPET-xx into any other type of power system. Contact your facilities manager or certified electrician if you are not sure what type of power is supplied to your building. To reduce the risk of shock, always plug the cord into a grounded power outlet.

Warnung - Die LCPET-xx ist für den Betrieb mit einphasigen Stromversorgungssystemen ausgelegt, die einen geerdeten neutralen Leiter haben. Um die

Gefahr elektrischer Schläge zu reduzieren, dürfen Sie das Gerät nicht an andere Stromversorgungssysteme anschließen. Wenn Sie nicht wissen, welche Stromart in Ihrem Gebäude zur Verfügung steht, bitten Sie Ihren Hausverwalter oder einen zugelassenen Elektriker um Auskunft. Schließen Sie das Gerät immer an eine geerdete Steckdose an, um Stromschläge zu vermeiden.

Danger - LCPET-xx est conçu pour un fonctionnement avec des systèmes d’alimentation mono-phasés pourvus d’un conducteur neutre mis à la terre. Pour limiter les risques d’accidents électriques, ne connectez pas LCPET-xx à un autre type d’alimentation. Contactez le directeur du site ou un électricien certifié si vous ne connaissez pas le type d’alimentation dont est pourvu le bâtiment. Pour limiter les risques d’accidents électriques, branchez toujours ce cordon sur une prise de terre.

Aviso - LCPET-xx ha sido concebido para funcionar con sistemas de alimentación monofásicos provistos de un conductor neutro puesto a tierra. Para disminuir el riesgo de accidentes eléctricos, no hay que enchufar este equipo a ningún otro tipo de sistema de alimentación. Hay que ponerse en contacto con el administrador de la instalación o con un electricista autorizado en caso de duda sobre el tipo de alimentación que posee el edi ficio. Para disminuir el riesgo de accidentes eléctricos, hay que conectar siempre este equipo a una toma de alimentación con conexión a tierra.

Caution - To ensure reliable operation of the LCPET-xx and to protect it from overheating, openings in the equipment must not be blocked or covered. The

LCPET-xx should never be placed near a radiator heat register.

Achtung - Um einen zuverlässigen Betrieb der LCPET-xx zu gewährleisten und sie vor Überhitzung zu schützen, dürfen Geräteöffnungen nicht verstopft oder abgedeckt werden. Die LCPET-xx sollte nicht in der Hähe von Heizkörpern aufgestellt werden.

Attention - Pour assurer le bon fonctionnement de LCPET-xx et pour le mettre à l’abri de toute surchauffe, les ouvertures ne doivent être ni entravées, ni recouvertes. LCPET-xx ne doit jamais être place à proximité d’un accumulateur de chaleur thermique.

Precaución - Para garantizar el buen funcionamiento de LCPET-xx y para protegerlo de un eventual recalentamiento, las aberturas no deben quedar obstruidas o recubiertas. LCPET-xx no debe jamás colocarse cerca de un acumulador de calor térmico.

Note: The LCPET-xx must be operated with the supplied line cord or with a line cord meeting IEC227 H03 VV-F or IEC227 H03 VVH2-F having conductors with a cross sectional area not less than .75 mm 2 .

IMPORTANT SAFETY INSTRUCTIONS

Read Instructions - All the safety and operating instructions should be read before the product is operated.

Retain Instructions - The safety and operating instructions should be retained for future reference.

Heed Warnings - All warnings on the product and the operating instructions should be adhered to.

Follow Instructions - All operating and use instructions should be followed.

Grounding - This product is equipped with a three-wire grounding-type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.

Outdoor Antenna Grounding - Since an outside antenna or cable system is connected to the product, be sure that the antenna or cable system is grounded to provide some protection against voltage surges and built-up static charges. Article 810 of the National

Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to the antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection of grounding electrodes, and requirements for the grounding electrodes.

Lightning - For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges.

Power Lines - An outside antenna system should not be located in the vicinity of overhead power lines or other light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them may be fatal.

Note to CATV System Installer - This reminder is provided to call the CATV systems installer's attention to Section 820-40 of the

NEC which provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

The Power LED activates within 3 seconds of plugging the LCP in. If this does not happen, unplug the power and refer to Page F - Troubleshooting Checklist

• The LCP Power Up Diagnostics run within 30 seconds of power on.

• The Ethernet Transmit LED will start to blink.

• The LCP will begin “scanning” the broadband if its configuration file server is not located locally.

• The Block Sync LED will illuminate.

• The Broadband Transmit LED can be noticed after the Block Sync LED illuminates.

• If there is transmit traffic on either the Ethernet or Broadband networks, you will see the activity

LEDs blink.
