Using the VTech Kidi DJ Mix is super easy! First, explore the sound grid to create different sound combinations. If you want to add your own touch, use the internal mic to record custom sound effects and vocal tags. Then, use the sliders to adjust the effects for a great remix. You can play around with adding or removing vocals and effects to fine - tune the mix and record your mash - up. For listening, you can either plug in headphones or use the built - in speaker. To connect your own music, use Bluetooth or an audio cable (make sure to have your own music player, audio cable, and headphones). There's also a music game where you can follow the rhythms to improve your DJ skills. When it comes to maintenance, keep it in a dry and clean place. Don't expose it to extreme temperatures or moisture. If it gets dirty, use a soft, dry cloth to clean it. Remember, this product is designed for kids aged 6 - 12, so make sure to supervise younger kids while using it.
