1. The normal working temperature of sound box equipment should be 18℃ ~ 45℃. Too low a temperature can reduce the sensitivity of some machines (such as electronic tube machines); Too high, easy to burn components, or make components early aging. Pay special attention to cool down and keep the air circulating in summer.

2, sound box equipment should not direct sunlight, but also avoid close to the heat source, such as the heater.

3. After the sound box is used up, the function keys should be reset. If the function key is no longer in position for a long time, the pulling button spring is in a state of stress for a long time, it is easy to cause dysfunction.

4. Before switching the power supply of the sound box, turn the volume potentiometer of the power amplifier to the minimum, which is one of the most effective means of protection for the power amplifier and the sound box. At this time, the power amplifier amplification is almost zero, at least in the wrong operation will not cause harm to the sound box.

5. Power on regularly. In the case of long-term use, especially in the humid, high temperature season, it is best to power for half an hour every day. In this way, the heat generated when the components of the machine work can be used to drive away moisture, to avoid the internal coil, speaker voice coil, transformer and other damp mold break.

6. Wipe the surface of the machine with a clean, damp cotton cloth every once in a while; When not in use, apply dust cover or cloth to cover the machine to prevent dust from entering.
