Product Principle:

By steadily rotating the generator crank, the speaker will emit keypad tones when the number keys are pressed, allowing simulation of emergency calls such as the police hotline (110), medical emergency hotline (120), and fire emergency hotline (119). It also produces sound and light effects of a siren.

Gameplay Points:

You can also dial 120 for the medical emergency hotline or 119 for the fire emergency hotline. Dialing 333 will prompt vocal instructions from the speaker on how to dial 110 for the police hotline. Dialing 444 will provide vocal instructions on how to dial 120 for the medical emergency hotline. Dialing 555 will provide vocal instructions on how to dial 119 for the fire emergency hotline.
