1. The audio system should not be exposed to direct sunlight and should also be kept away from heat sources such as heaters.

The normal operating temperature for audio equipment should be between 18 ℃ and 45 ℃. Too low a temperature can reduce the sensitivity of certain machines (such as electronic tube machines), while too high a temperature can easily burn out components or cause them to age prematurely. In addition, special attention should be paid to cooling and maintaining air circulation in summer.

3. Before turning on or off the audio power, the volume potentiometer of the amplifier should be turned to the minimum, which is the most effective way to protect the amplifier and speakers. At this point, the power amplification of the amplifier is almost zero, and at least it will not cause damage to the speaker in case of misoperation.

4. When starting up, first turn on the CD player and turn the volume potentiometer of the amplifier to the minimum; When shutting down, the amplifier should be turned off first to completely disable its amplification function, and then the front-end equipment should be turned off. This way, even if a large surge current is generated, it will not affect the sound system.

5. After the speaker is used up, all function keys should be reset. If the function key is not reset for a long time, its pulling button spring will be under force for a long time, which can easily cause functional disorders.
