3, before resetting the AO Smith water heater filter element, first make sure to stop heating and disconnect the power supply. This is a very important safety measure to ensure that no current will pass through the water heater. In addition, close the water valve to prevent water from entering the water heater. Wait a while to make sure the water temperature inside the water heater drops to a safe range. The filter element of AO Smith water heaters is usually located on the front or bottom of the water heater.
4, switch the machine again. Set -- General -- Secure -- Clear certificates. If screen lock Settings other than passwordIn other lock modes, the screen is gray and the message "Already stored by administrator, encryption policy, or certificate" is displayed. Or contact after-sales consultation, or at that time to provide instructions in accordance with the instructions, generally have a reset function.
5, Smith water purifier needs to be installed with a special card activation, otherwise it can not be used. After the activation needs to be pressed on the tap, there is a total of 8 digits of the activation number, and then according to the activation number of the machine, after some operation in the tap, the activation can be used normally. The user must find a professional to install according to the installation specifications described in the manual, and followUse the water purifier in the instructions.
6, brush in the anti-counterfeiting identification area of the filter element to reset and use. In order to ensure the quality of the filter water, Smith also added the filter anti-counterfeiting identification function on the fuselage, only the original filter anti-counterfeiting identification card in the filter anti-counterfeiting identification area brush to reset the use, you can enter the official website, enter the anti-counterfeiting code, the two-dimensional code on the filter is the anti-counterfeiting code, sweep it.
1, the original chip decryption data line has a variety of usesThe way. First, the original chip decryption data line can be used to study and analyze the internal structure and function of the original chip. By decrypting the data line, we can gain an in-depth understanding of the working principle and design concept of the original chip. This is extremely valuable for chip manufacturers and technology researchers, as they can improve designs and strengthen security by analyzing decrypted data lines. First, for some customers, chip Decryption provides custom chip design and manufacturing services, which opens up new application areas and business opportunities for customers. Secondly, the technology and method of chip decryption can be applied in maintenance and after-salesIn the service, customers can better understand and master the use of the chip.
3, AT88SC0104D, etc., among which there are also specially designed chips with encryption algorithms for professional encryption or functional chips designed to verify the manufacturer's code work, such chip industry can achieve the purpose of preventing electronic products from copying. With the help of special equipment or homemade equipment, using the vulnerabilities or software defects on the design of the single-chip microcomputer chip, through a variety of technical means, you can extract key information from the chip and obtain the program in the single-chip microcomputer, which is called single-chip decryption.
4, chip decryption, also known asFor single-chip decryption, IC decryption, etc., because the single-chip chip in the formal product is encrypted, the program can not be read directly using the programmer. However, sometimes for some reasons, it is necessary to get the internal procedures of the single chip microcomputer to refer to the study, find the lost information or copy some chips, which needs to be decrypted by the single chip microcomputer.
5, ic cracking, also known as single-chip decryption, chip decryption, ic chip decryption (MCU) generally have internal EEPROM/FLASH for users to store programs and working data. In order to prevent unauthorized access or copy of the single chip computer programMost microcontrollers have encryption locks to locate or encrypt bytes to protect on-chip programs. 6, the main uses of the chip include but are not limited to the following aspects: computing and processing data: the chip can be used in computers, mobile phones, tablets and other devices in the central processing unit (CPU), the execution of various algorithms and operations, processing and manipulation of data.
