The openings should never be blocked by placing the product on a bed, sofa, rug, or other similar surface. This product should not be placed in abuilt-in installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer’s instructions have been adhered to. •Power Sources-This product should be operated only from the type of power source indicated on the marking label. If you are not sureof the type of power supply to your home, consult your product dealer or local power company. For products intended to operate from battery power, orother source, refer to the operating instructions. The lighting flash with arrowhead symbol, within an equilateral triangle is intended to alter the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock o persons. The exclamation point within a equilateral triangle is intended to alert the user to the presence of important operating and maintenance(Servicing) instruction in the literature accompanying the appliance. CAUTION : TO REDUCE THE RISK OF ELECTRIC SHOCK. DO NOT REMOVE COVER (OR BACK). NO USER SERVICEABLE PARTS INSIDE REFER SERVICING TO QUALIFIED SERVICE PERSONNEL 1 Example of Antenna groundingas per National Electric Code, ANSI/NFPA 70 (NEC –National Electrical Code) ANTENNA LEAD IN WIRE ANTENNA DISCHARGE UNIT (NEC SECTION 810-20) GROUNDING CONDUCTORS (NEC SECTION 810-21) GROUND CLAMPSPOWER SERVICE GROUNDING ELECTRODE SYSTEM (NEC AR 250, PART H) GROUND CLAMP ELECTRIC SERVICE EQUOPMENT Note to CATV System Installer This reminder is provided to call the CATV system installer’s attention to Article 820-40 of the NEC that 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. •Grounding or Polarization-This product may be equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. •Alternate Warnings-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. •Power-Cord Protection-Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product. •Productive Attachment Plug-The product is equipped with an attachment plug having overloadprotection. This is a safety feature. See Instruction Manual for replacementor resetting of protective device. If replacement of the plug is required, be sure the service technician has useda replacement plug specified by the manufacturer that has the same overload protection as the original plug. •Outdoor Antenna Grounding-If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as 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, groundingof the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the gr…

Operational Description Functionality The NU2V-2500 is the box, which is placed between the satellite dish and the TV set or other electronic home equipment. It decodes the incoming signals, verifies the access rights and outputs clear picture, sound or other services in the appropriate format. Description The decoder is functionally organized as indicated in the following figure. NIM(Network Interface Module) NIM(BS0054) consists of TUNER and QPSK Demodulator. The signal received by Antenna and LNB will be transmitted to TUNER. TUNER is designed to select one transponder and convert to I & Q signal. The I & Q signal from TUNER will be transmitted to QPSK Demodulator which is designed to demodulation and FEC(Forward Error Correction) decording. The output of QPSK Demodulator is parallel format of TS (Transport Stream) signal. Integrated STB Controller Integrated STB Controller(U101) consists of Demultiplexer, MPEG Decoder, Video Encoder and Microprocessor. The TS signal from NIM will be transmitted to Demultiplexer. Demultiplexer is designed to select wanted Video PES (Packetized Elementtary Stream) and Audio PES. These signal will be transmitted MPEG Decoder to make decompressed digital Video and Audio signal. Digital Video signal will be transmitted Video Encoder to convert analog Video output. Digital Audio signal will be transmitted to external Digital-to-Analog converter. The Microprocessor is designed to control all other devices. Flash Memory Flash memory(U201) is used to store main software and default Satellite Information. Main software and Satellite Information can be up-dated by PC through serial communication. And also the Satellite Information can be up-dated by customer when he changes some data. SDRAM SDRAM(U202) is temporary memory, and it is used for main software, demultiplexing and MPEG decording. VCXO The VCXO(Y401) is designed to generate system clock signal. The system clock is used for demultiplexing, MPEG decording and to work of Microprocessor. It has DC voltage input port which is used to adjust output frequency. Video Filter The Video Filter(L601, L602, L603) is designed to remove high-frequency noise on Video signal. Audio DAC Τηε Αυδιο ∆ΑΧ(Υ501)ισ δεσιγνεδ το χονπερτ τηε διγιταλ αυδιο σιγναλ(Ι2Σ φορματ).
