Using the Behringer C210B is simple. First, make sure the battery is charged. You can charge it up to 80% in 7 hours and fully in 10 hours. Once charged, turn on the speaker. To play music, connect your Bluetooth device like a phone or computer. Just swipe and select the speaker from your Bluetooth settings. You can also use the 3 - channel mixer to adjust the sound with individual gain controls.
When using it, avoid exposing the speaker to extreme temperatures or moisture. Also, don't place it on unstable surfaces.
For maintenance, keep the speaker clean. You can use a soft, dry cloth to wipe the enclosure and the protective grilles. If you're not using it for a long time, store it in a cool, dry place with the battery charged to about 50%. Enjoy your music with the Behringer C210B!
