2 Important Information 10. Grounding or Polarization - This video product is equipped with either a three prong plug for 120 Vac use. It is to be inserted into only the type of receptacle for which they specifically designed . Do not cut off the round grounding pin in order to be able to fit into a two prong receptacle as this could cause injury and will void the warranty. 11. Power Sources - This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supplied to your home, consult your appliance dealer or local power company. 12. Power-cord Protection - Power-supply cords should be routed so they are not likely to be walked on or pinched by items placed upon or against them. Pay particular attention to cords and plugs, convenience receptacles, and the point where they exit from the appliance. 13. 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 outlet. 14. Power Lines - An outside antenna system should not be located in the vicinity of overhead power lines, other electric light or power circuits, 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. 15. Overloading - Do not overload wall outlets and extension cords as this can result in risk of fire or electric shock. 16. Object and Liquid Entry - Never push objects of any kind into this product through openings as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind on the product. 17. Servicing - Do not attempt to service this product yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel. 18. Damage Requiring Service - Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following conditions: a. When the power-supply cord or plug is damaged. b. If liquid has been spilled, or objects have fallen into the product. c. If the product has been exposed to rain or water. d. If the product does not operate normally by following the operating instruction. Adjust only those controls that are covered by the operating instructions. An improper adjustment may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation. e. If the product has been dropped or the cabinet has been damaged. f. When the product exhibits a distinct change in performance - this indicates a need for service.

Replacement Parts - When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original parts. Unauthorized substitutes may result in fire, electric shock or other hazards. 20. Safety Check - Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating conditions. 21. Outdoor Antenna Grounding - Before attempting to install this product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. a. Use No.10 AWG (5.3mm ) copper, No.8 AWG (8.4mm (aluminum, No.7 AWG (10mm ) copper-clad steel or bronze wire or larger, as ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart. c. Mount antenna discharge unit as close as possible to where lead-in enters house. d. A driven rod may be used as the grounding electrode where other types of electrode systems do not exist. Refer to the National Electrical Code, ANSI/NFPA 70-1984 for information. e. Use jumper wire not smaller than No.6 AWG (13.3mm ) copper or equivalent, when a separate antenna grounding electrode is used. NOTE TO THE 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 PAR- TICULAR, SPECIFIES THAT THE CABLE GROUND SHALL BE CON- NECTED TO THE GROUNDING SYSTEM OF THE BUILDING, AS CLOSE TO THE POINT OF CABLE ENTRY AS PRACTICAL.

Description The PICO MACOM, INC. PM45 Modulator has been specifically designed for adjacent channel headend use. It provides high stability and superior picture and sound quality and assures reliable operation even in the most crowded systems. The high frequency and extremely high accuracy Phase Lock Loop oscillator allows the unit to meet the frequency offset and stability requirements of FCC Docket 21006, even at hyperband output channels. Modular construction allows the unit to be reconfigured to any output channel by qualified service centers. Superior out-of-band carrier to noise is achieved by output amplifier bandpass filtering in addition to IF SAW filtering. Features • SAW filtered for superior vestigial side band shaping & harmonic reduction • IF modulation for superior harmonic reduction and modulation quality • Encoder compatibility, using an external IF loop-thru, to accommodate pay-per- view or scrambled signals • LED overmodulation indicators • Excellent audio and video linearity • Compatible with BTSC MTS Stereo audio • Three year warranty • 13⁄4" low profile rack mounting • Low power consumption • 45dBmV minimum output • Spurious outputs down 60 dB • Complies with FCC Docket 21006 requirements for CATV systems
