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 oper-  
ated 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 com-  
pliance 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 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 A prescrites dans le Règle-  
ment sur le brouillage radioélectrique publié par le ministère des Communications

Remember to check the attenuation and bandwidth of the fiber optic cable. The  
system will only operate properly if these specifications fall within the range of the

Troubleshooting:  
3. Todas las advertencias en el aparato eléctrico y en sus instrucciones de oper-  
Multimode fiber optic cable contains an optical fiber with a light carrying “core” that  
is only .0025 inches (62.5 microns) in diameter. Single mode fiber optic cable has an  
even smaller “core”, only 00032 to .0004 inches (8-10 microns). This is smaller than  
a human hair! Therefore, any minute particles of dirt or dust can easily block the fiber  
from accepting or radiating light. To prevent this from happening, always use the  
provided dust caps whenever optical connectors are exposed to air. It is also a good  
idea to gently clean the tip of an optical connector with a lint-free cloth moistened  
with alcohol whenever dust is suspected.  
ación deben ser respetadas.  
4. Todas las instrucciones de operación y uso deben ser seguidas.  
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  
The status of the VIDEO and AUDIO indicator LEDs should provide the first clue as  
to the origin of an operational failure. If these are off, it usually means that the fiber is  
broken or has too much attenuation. Next, be certain that the input and output signal  
connections are correct.

8. Servicio—El usuario no debe intentar dar servicio al equipo eléctrico más allá  
a lo descrito en las instrucciones de operación. Todo otro servicio deberá ser  
referido a personal de servicio calificado.  
If, after reviewing the above possibilities, the system is still not operating, please  
contact the Black Box Tech Support for further assistance  
9. El aparato eléctrico debe ser situado de tal manera que su posición no interfi-  
era su uso. La colocación del aparato eléctrico sobre una cama, sofá, alfombra  
o superficie similar puede bloquea la ventilación, no se debe colocar en libre-  
ros o gabinetes que impidan el flujo de aire por los orificios de ventilación.  
Maintenance:  
The only maintenance of the AC1020A system that can be provided by the user is to  
ascertain that the optical connectors are free of dust or dirt that could interfere with light  
transmission and that electrical connections are secure and accurate. DANGER!Always  
disconnect the transmitter power before removing the optical fiber from the unit! For  
assistance with all other repairs, please contact Black Box technical support.  
10. El equipo eléctrico deber ser situado fuera del alcance de fuentes de calor  
como radiadores, registros de calor, estufas u otros aparatos (incluyendo am-  
plificadores) que producen calor.

Indicator LEDs:  
The transmitter and receiver units in the A1020A system each have three integral in-  
dicator LEDs that are used to monitor the state of the unit. Their status is as follows:  
TRANSMITTER and RECEIVER:  
Power: (Green) Indicates that correct power has been applied.  
TRANSMITTER:  
Video: OFF: Indicates no video detected on the input.  
BLINKING GREEN: Indicates either H or V sync detected at the input  
but not on both.  
STEADY GREEN: Indicates both H and V sync detected on the input.  
Audio: OFF: Indicates no audio detected on the transmitter unit.  
BLINKING: Indicates audio detected on the transmitter unit.  
RECEIVER:  
Video: OFF: Indicates no video detected over fiber and, as a result, no  
video present on output.  
BLINKING GREEN: Indicates either H or V sync detected over the  
fiber but not both.  
STEADY GREEN: Indicates both H and V sync detected over the fiber  
and, as a result, video present on the output.  
Audio: OFF: Indicates no audio detected over fiber and, as a result, no active  
audio detected by the receiver unit.  
BLINKING: Indicates audio detected over fiber and, as a result,  
active audio detected by the receiver unit.

The RGBHV Video with StereoAudio Fiber Optic Transmission System (AC1020A-  
V/A System) is a transmitter/receiver pair that transmits a single channel of RGBHV  
and two audio channels over one single mode or multimode fiber.  
Optical Connectors...............................ST  
The system’s all digital encoding delivers noise-free transmissions that retain all of  
their initial parameters, regardless of fiber optic cable attenuation. System operation  
may be easily monitored using integral indicator LEDs on each unit that continuously  
signify the presence of baseband video and audio signals.
