The connection between the display case and the grounding metal parts should have a low impedance value. The following tests are carried out to determine whether they are qualified or not. During the transient interference injection, the voltage drop between the controller shell and the grounding metal parts is measured. It is required that the voltage Umax on the shell should not be greater than 0.8V (TTL low level threshold value) during the whole process of interference injection. According to some characteristic parameters of interference injection, the required grounding impedance range is calculated: 0-100MHz. In the frequency band, the impedance value shall not exceed 60 milliohms. 2. In addition to the good grounding of the display case, all the input and output points of sensors, loads and so on connected with the display screen must be closed-
loop, that is, all input and output points must be connected with the display screen accordingly. 3. The common reasons for the unsuccessful burning of picture libraries are as follows Configuration file does not exist or content error Naming errors for folders to be burned, files not to be burned, or file naming format errors U-disk or motherboard Ontology Unburnt or version error of underlying program FCC Statement Any Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause undesired operation. FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment .This equipment should be installed and operated with minimum distance 20cm between the radiator& your body. 10 SECD-7I0A-35 User Manual Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the fol following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the recreceiver is connected. Consult the dealer or an experienced radio/TV technician for help. 11
