Question about Amewi U.S. Military Truck 8x8 Dump Truck

Good day I got the Super Truck today and put it into operation right away - simply brilliant :-) The engine noise works, >>>can it be turned up or down, maybe with the remote control? I found the different flashing modes on the cabin ceiling to change (button). I have seen in a video that there are also different sounds to switch (siren, American siren, etc.). >>Can this also be switched on / off somehow on this model?) Thank you very much for your feedback.
