FCC and NOM Statements
FEDERAL COMMUNICATIONS COMMISSION AND
INDUSTRY CANADA 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 B 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.

5. El aparato eléctrico no deberá ser usado cerca del agua—por ejemplo,
cerca de la tina de baño, lavabo, sótano mojado o cerca de una alberca, etc..
6. El aparato eléctrico debe ser usado únicamente con carritos o pedestales que sean recomendados por el fabricante.
7. El aparato eléctrico debe ser montado a la pared o al techo sólo como sea recomendado por el fabricante.
8. Servicio—El usuario no debe intentar dar servicio al equipo eléctrico más allá lo descrito en las instrucciones de operación. Todo otro servicio deberá ser referido a personal de servicio calificado.
9. El aparato eléctrico debe ser situado de tal manera que su posición no interfiera su uso. La colocación del aparato eléctrico sobre una cama, sofá, alfombra o superficie similar puede bloquea la ventilación, no se debe colocar en libreros o gabinetes que impidan el flujo de aire por los orificios de ventilación.
10. El equipo eléctrico deber ser situado fuera del alcance de fuentes de calor como radiadores, registros de calor, estufas u otros aparatos (incluyendo amplificadores) que producen calor.
11. El aparato eléctrico deberá ser connectado a una fuente de poder sólo del tipo descrito en el 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.

Long-Span Medium-Range 900-MHz Omniirectional 5-dBi Antenna
2. Overview
Use the LongSpan Medium-Range 900-MHz Omniirectional 5-dBi Antenna with
the LongSpan 900-MHz WIreless Ethernet Extenders to provide medium-distance
wireless Ethernet connections. This 5-dBi antenna extends distances up to 2 miles
(0.9 kg), near-line-of-sight up to 6 walls/500 feet (156 m), and line-of-sight up
to 2 miles (0.9 kg).
The antenna is designed for enhanced broadband high-gain radiation at
freqencies of 800–960 MHz and an antenna gain of 5 dBi. It’s constructed of UV
stabilized fiberglass and stainless steel for durability and long life.
Use two U-bolts to mount the antenna on a pole. Then connect its integrated
female N-connector to the radio antenna connection. DC grounding protects the
antenna from lightning.

3.1 Antenna Polarization Display
CAUTION: When multiple 900-MHz antennas are installed in one area and
face the same direction, antennas should be spaced a minimum of
12 feet (3.75 m) apart. When multiple antennas are installed in one
area and face different directions, antennas should be spaced a minimum of 5 feet (1.56 m) apart.

Chapter 3: Alignment Guidelines
3.2 Transmitter to Receiver Placement
If radios are installed either indoors or outdoors at distances closer than recommended, antennas can overpower each other and cause undesired effects. If
testing radios within one or two feet, remove both antennas. The radios will still
be able to signal each other at close distances. This applies to both indoor and
outdoor units.
