Using this Hape DJ studio is super easy. First, make sure to insert 3 AA 1.5V batteries (you'll need to buy them separately). Your little one can start by turning the knob to pick an instrument sound or a fun sound effect and play the 18 - key piano. To add a background tune, press the middle button. You can change the speed of the music with the tempo slider. For that cool DJ feel, use the scratchable black record. When your child gets the hang of it, they can mix different elements to create their own music. As for maintenance, keep the toy away from water and extreme temperatures. If it gets dirty, use a dry or slightly damp cloth to clean it. Also, when not in use for a long time, remove the batteries to avoid damage to the toy.
