On August 26, 2024, at 5:00 PM, while driving along the Jing-Mi Road inbound direction towards Beijing near Dongxin Ditan Village bus stop, I heard a frequency of 438.450 - 5.5 T88.5. A pedestrian triggered the anti-theft alarm on an electric scooter, and approximately 10 meters away, the handheld device also started emitting an alarm sound! Unfortunately, at that time, I couldn't clearly see the brand of the electric scooter.
