How to use portable speakers

　　Insert the memory card or U disk directly into the speaker, and you can play it after turning it on.

　　One is the use environment. Try not to place it in direct sunlight, and do not place heavy objects on top of the Bluetooth speaker to avoid deformation of the shell. In addition, pay attention to the ambient temperature of portable Bluetooth speakers. The normal ambient temperature of general audio equipment should be 18℃～45℃. If the temperature is too low, it will reduce the sensitivity of some parts such as electronic tube machines.

　　The second is to turn on and off. Some split-type portable Bluetooth speakers should first turn on the main audio source such as the CD player, and then turn on the audio unit; when shutting down, turn off the audio unit first, and then turn off the main audio source. The volume switch of the power amplifier should also be turned to the minimum when turning on the power to avoid instantaneous loud volume damage to the audio.

　　Third, it is volume adjustment. When using a portable Bluetooth speaker to enjoy music, avoid turning the volume of the speaker to the maximum when it is turned on. Since the components of the speaker have not yet passed the preheating stage when the speaker is turned on, a larger volume will make it work at full capacity instantly, causing The components are damaged, and doing so for a long time will cause some internal fragile audio components to fail.
