Ultrasonic distance voice prompter user manual. This product adopts advanced ultrasonic ranging technology to realize the distance detection between objects and probes, with a detection accuracy of 2 cm. The product not only can make real-time voice prompts for the detected distance status, but also can freely set a threshold value, which can make voice and light alarms when within the threshold value.
The ultrasonic range‑finding voice reminder uses ultrasonic sensors to measure distance between the device and an object with centimeter‑level accuracy. It provides real‑time voice prompts and optional visual‑audio alarms when the measured distance falls within preset thresholds.
The manual explains power‑on procedures, how to set product and probe numbers, configure prompt and alarm distances, and use the built‑in alarm timeout function. It also includes technical specifications, a wiring diagram, and safety notes. This manual is written in Chinese.
