Yes, you can operate most toy crane machines without the music or sound effects! Many modern models come with built-in options to mute or adjust the audio. Typically, you'll find a volume control knob or a mute button on the main control panel or settings menu of the machine. For older or simpler models, you might need to manually disconnect the internal speaker wires, but this should be done carefully to avoid damaging the device. Operating the crane silently can be great for reducing noise in quiet environments or for personal preference. Always refer to the user manual for specific instructions tailored to your model. If you're unsure, contact the manufacturer or a professional technician for assistance to ensure safe and proper mute operation.
