1, sound equipment normal working temperature should be 18℃ ~ 45℃. Low temperature will reduce the sensitivity of some equipment (such as electronic tube machine); Too high is easy to burn components, or components early aging. In summer, special attention should be paid to cooling and maintaining air circulation.

2, audio equipment avoid direct sunlight, but also to avoid close to the heat source, such as heating.

3, sound equipment used up, each function key to reset. If the function key is out of position for a long time, the pulling button spring is in a state of force for a long time, which is easy to cause dysfunction.

Before 4, switch sound power supply, turn the volume potentiometer that put work result to the smallest, this is to put work result and sound box one of the most effective protective means. At this time the power that result puts is magnified almost zero, also unapt when operating by mistake is harmful to sound box at least, had better want to shut down plug when plug out a line plug out.

5, when starting the machine from before to after, namely first open CD machine, open again before and after class, the volume potentiometer of the power put when starting the machine turns to the smallest. When shutting down, close first result is put, the magnify function that lets result put is closed completely, when you turn off front end equipment again at this time, no matter produce again big impact current also won't suffer reach result to put and sound box. The volume potentiometer that should put the result when shutting down likewise is rotated to the smallest, close or put hind can close again before with CD machine.
