How does Qian Xun wake up the offline locator function?

Send SMS command status # or dial SIM card number. According to the relevant public information, check the equipment status. If you don't receive any SMS reply and turn it off, you need to check whether the installation and wiring are correct. The locator needs to face up, and there are no metal objects. If it is wired, it is best to let professionals install it, and check whether the battery of the equipment is charged and in normal startup state. If the device is charged, turn on the battery switch to restore the positioner to offline state.
