N7ZEC420CABLE MODEM

EC420 User’s Manual Introduction Important Rules for safe Operation In addition to the careful attention devoted to quality standards in the manufacture of your TurboComm DOCSIS Cable modem, safety is a major factor in the design of every product. However, safety is your responsibility, too. This section lists important information that will help assure your enjoyment and proper use of the TurboComm Cable Modem and accessory equipment. Please read them carefully before operating and using your modem. Installation Read and Follow Instructions You should read all the safety and operating instructions before operating the modem. Follow all operating instructions. Retain Instructions You should save all the safety and operating instructions, for your future reference. Heed Warnings Comply with all warnings on the products and in the operating instructions. Check Power Sources Operate this product only from the type of power source indicated on the product’s marking label. If you are not sure of the type of power supplied to your home, consult your dealer or local power company. Be Careful of Overloading Do not overload wall outlets or extension cords, as this can result in a risk of fire or electric shock. Overloaded AC outlets, extension cords, frayed power cords, damaged or cracked wire insulation, and broken plugs are dangerous. They may result in a shock or fire hazard, Periodically examine the cord, and if its appearance indicated damage or deteriorated insulation, have it replaced by your service technician. Protect Power Cords Route power supply cords so that they are not likely to walked on or pinched by items placed upon or against them. Pay particular attention to cords where they are attached to plugs and convenience receptacles, and examine the point where they exit from the product. Check Ventilation Slots and openings in the enclosure are provided for ventilation to ensure reliable operation of the product and to protect it from overheating. Do not block or cover these openings. Never block these openings by placing the product on a bed, sofa, rug, or other similar surface. Never place this prodct near or over a radiator or heat register, or any other heat source (including amplifiers). Do not place this product in a built-in installation, such as a bookcase or equipment rack, unless you provide proper ventilation. Do Not Use Accessories Do not use attachments, unless they are recommended by TurboComm, as they may cause electrical or fire hazards, Use the Recommended AC Adaptor You must use the adaptor that comes with your TurboComm Cable Modem. Do Not Use Near Water Do not use this product near water – for example, near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement or near a swimming pool, and the like. Do Not Place Near High Temperature Source – for example near a steamer, kitchen range fire, and the like. Use Caution in Mounting This Product Do not place this product on an unstable surface or support. The product may fall, causing serious injury to a child or adult, as well as serious damage to the product. Use Care in Moving Product and Cart Combinations Quick stops, excessive, force and uneven surfaces may cause the product and cart combination to overturn. Ground the Cable System Be sure that the outside cable system is grounded, so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electric Code, ANSI/NFPA No. 70-1984(Section 54 of the Canadian Electrical Code, Part I) provides information with respect to proper grounding of the cable modem. Do not disconnect RF cable from your TurboComm Cable Modem while the power to your modem is on Use Unplug Power Before Cleaning Do not use liquid cleaner or aerosol cleaner. Use a damp cloth for cleaning. Keep Objects Out of Openings Never push objects of any kind into this product through openings, as they may touch dangerous voltage or “short-out” parts, which could result in a fire or electric shock. Never spill liquid on the product. Protect From 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, and disconnect the cable system. This will prevent damage to the product due to lightning and power line surges. Take at least 10 seconds between DC plug off and on. Service Do Not Remove Covers 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. Unplug this product from the wall outlet carefully, as the AC adaptor may be hot. Refer servicing to Qualified Service Personnel Under the Conditions Listed Below When the power supply cord or plug is damaged. If liquid has been spilled or objects have fallen into the product. If the product has been exposed to rain or water. If the product doesn’t operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions. If the product has been dropped or the cabinet has been damaged. When the product exhibits a distinct change in performance, such as the inability to perform basic functions – this indicates a need for service. Require Safety Check Upon completion of any service or repairs to this product, ask the service technician to perform safety checks recommended by TurboComm to determine that the product is in safe operating condition. Overview The modem provides you with high-speed data communications over the television cable network by following the widely accepted DOCSIS/MCNS standards being developed by the multimedia cable network system consortium. Those standards offer a combination of high performance and interoperability among many of the cable system operators in North America. Working of Cable modem Digital signals are represented by high and low electrical voltage levels. And how fast t…

A mouse was connected to the mouse port of IBM PC. And A keyboard was connected to the mouse port of IBM PC. And a printer was connected to the parallel port. An external modem connected the serial port and the external modem connected with two un-terminated telephone cables on the line and phone jack. TEST SITE MAX LIGHT MEASUREMENT REPORT Page: 7/272 Report Number: MLT0510P15002 FCC ID: N7ZEC420 Technology Lab 1.5 Test Procedure All measurements contained in this report were performed according to the techniques described in Measurement procedure ANSI C63.4-2003 "Measurement of un-Intentional Radiators." 1.7 General Test Condition The conditions under which the EUT operates were varied to determine their effect on the equipment's emission characteristics. The final configuration of the test system and the mode of operation used during these tests was chosen as that which produced the highest emission levels. However, only those conditions which the EUT was considered likely to encounter in normal use were investigated. The system's radiated and conducted emissions were investigated while the computer alternately transferred data to the EUT (1000 bytes). Run “Ping (IP Address -T –L 1000)” comment which sent a continuous stream of 1000 Bytes data to EUT and transferred data to and from the EUT was proven to worst case emissions. The system's physical layout and cabling was randomly arranged to ensure that maximum emission levels were attained.
