When the display device emits an acoustic signal, it shall simultaneously emit a vibration alert. The display device shall have a manual silencing function. When a manual silencing operation is performed, the vibration alert shall also stop simultaneously.
5.1.8 The display device shall have a manual self check or power on self check function to check the functionality of its indicator lights, display screen and audible/visual components.
5.1.9 The display device shall have an internal timer or be capable of automatically adjusting the clock via a wireless communication network. The daily timing error of the internal timer shall not be greater than ±0.5 s, and the operation of the internal timer shall not be affected by the operating status of the display device.
5.1.10 The maximum communication distance between the display device and a terminal device should not be less than 1000 m, and the maximum communication distance between the display device and a relay device should not be less than 200 m.
5.1.11 When the display device has a positioning function, the positioning error for continuous positioning type display devices intended for outdoor use only should not be greater than 10 m, and for continuous positioning type display devices intended for indoor use, the positioning error should not be greater than 5 m; the positioning error for anchor positioning type display devices intended for outdoor use only should not be greater than 50 m, and for anchor positioning type display devices intended for indoor use, the positioning error should not be greater than 20 m.
5.1.12 When the display device has a remote measurement function, the maximum effective distance for the display device to complete the check in function interaction with the remote measurement point should not be greater than 5 m.
5.1.13 The display device shall have complete packaging at the time of product delivery. The packaging shall contain a quality inspection certificate and a Chinese instruction manual.
