To use these loudspeakers, first, connect them to the correct power supply that comes with them. Make sure the power supply is properly plugged in and switched on. Place the loudspeakers in a suitable location where sound can spread well. When using, avoid exposing them to extreme temperatures or humidity. For maintenance, keep the loudspeakers clean by gently wiping them with a dry cloth regularly. If there are any problems, don't try to open them yourself, but contact the manufacturer's customer service.
