The piano should stay away from the window. When the piano must be placed next to the window, please use thicker curtains. To avoid getting wet in rainy days, don't put it near the bathroom and kitchen. At the same time, it is kept moderately dry, and the piano requires high environmental humidity. In order to prevent the piano from getting wet. Users are advised to maintain the piano in strict accordance with the instructions. Users with air conditioning at home can turn on the air conditioner to a humid state to prevent it from getting wet. Try to ensure that the wood is not exposed to the sun and does not deform locally. If the piano does not sound on time due to use and temperature and humidity changes, please call the dealer's after-sales service department and send professionals to the door for debugging. When the humidity is too high and the room temperature rises sharply, the moisture may condense on the strings and other metal parts, leading to rust. The structure of wool and felt will also change greatly because of inhaling too much water, which will make the beating machine move slowly and produce noise. Pay more attention to the humidity change of the piano to prevent mildew. Therefore, we should cultivate the maintenance of the piano at ordinary times.
