  What are the precautions for the use of handheld megaphones？

  1、Hand-held megaphone is a professional loudspeaker device. It has high volume and power when in use. Please do not put the microphone close to your ears. When there is harsh noise during indoor use, just turn down the volume.

  2、During use, when there are frequent power failures, it means that the battery has been used up. Please turn off the megaphone and charge it in time. Because the lithium battery does not have a memory effect, please do not use up the battery completely during daily use, but always keep it in a fully charged state.

  3、When not using the megaphone for a long time, please fully charge the lithium battery for storage, and charge the battery every 1-3 months to avoid aging of the lithium battery.
