[. . . ] (20) The recommended operating conditions are conditions in which the normal operation of this product is guaranteed. All the rated values of the electrical specifications are guaranteed within these conditions. Always use the product within the range of the recommended operating conditions. Otherwise, the reliability of the product may be degraded. (21) This product has a glass display surface. Design your system so that excessive shock and load are not applied to the glass. Exercise care that the vent at the corner of the glass panel is not damaged If the glass panel or vent is damaged, the product is inoperable. (22) Do not cover or wrap the product with a cloth or other covering while power is supplied to the product. (23) Before turning on power to the product, check the wiring of the product and confirm that the supply voltage is within the rated voltage range. If the wiring is wrong or if a voltage outside the rated range is applied, the product may malfunction or be damaged. (24) Do not store this product in a location where temperature and humidity are high. This may cause the product to malfunction. Because this product uses a discharge phenomenon, it may take time to light (operation may be delayed) when the product is used after it has been stored for a long time. In this case, it is recommended to light all cells for about 2 hours (aging). (25) This product is made from various materials such as glass metal, and plastic. When discarding it, be sure to contact a professional waste disposal operator. (26) If faults occur due to arbitrary modification or disassembly, HAIER is not responsible for function, quality or other items. (27) Use of the product with a combination of parameters conditions or logic not specified in the specifications of this product is not guaranteed. If intending to use the product in such a way, be sure to consult HAIER in advance. PDF "pdfFactory Pro" www. fineprint. com. cn -7- 3.
