Using this Meyer Sound MM - 4XP Mini Self - Powered Loudspeaker is easy. First, connect your audio source to the speaker. Since it doesn't have a power supply, you need to use your own suitable power source to power it up. When using, place it in a stable position away from heat sources and water. For maintenance, keep it clean by gently wiping it with a dry cloth regularly. Don't use abrasive cleaners as they may damage the speaker's surface. If you encounter any problems, it's advisable to consult a professional technician.
