To use the cellular network, you have to install a 4G SIM card and\nturn on the cellular network first. The robot will connect to the Wi-Fi network first if both cellular\nand Wi-Fi networks are available. If the Wi-Fi signal is weak, the robot will automatically switch\nto the cellular network instead.\n3.4.2.1 Install a SIM Card\nStep 1 Remove the cover of the SIM card slot with a hex key.\nStep 2 Insert a SIM card and reinstall the cover.\n3.4.3 Turn on Cellular Network\nTurn on Cellular Network in the Settings > Network Settings interface. A 4G signal symbol will\nappear on the top bar.\nCaution\nOperations such as switching languages, importing music from mobile phones, and downloading pushed\nadvertisements must be performed under a Wi-Fi network.\n3.5 Auto Charging\nKettyBot supports self-charging. If you have purchased a charging pile and have set up the pile's\nlocation during mapping, when the battery level of the robot falls below 10%, it will automatically\nreturn to the charging pile after the current task is completed. You may also tap Charge Now on\nthe screen to return the robot to the charging pile for charging.\nKettyBot Pro Operation Guide\nVersion: V9.9 Operation Guide\n41\nNote\nThe charging pile is an optional accessory and can be purchased separately.\n3.6 Docking Instructions\nKettyBot supports three docking modes. In actual scenarios where multiple robots cooperate, users\ncan select any docking mode during mapping. This section only covers the description of the three\ndocking modes. For details about mapping, please contact our technical engineers.\nThree docking modes:\nOne-to-one Docking mode: Each robot has its fixed pickup location (docking location).\nFree Docking mode: Set multiple pickup locations (docking locations) for the robot to\ndock by priority, i.e., the robot chooses the nearest pickup location for docking.\nWaiting mode: Set temporary docking location. When the robot has no task and there's\nno vacancy at the pickup locations (docking locations), the robot docks at the temporary\ndocking location. Once a vacancy appears at a pickup location (docking location), the\nrobot automatically goes there for docking.\nKettyBot Pro Operation Guide\nVersion: V9.9 Operation Guide\n42\n4.

To use the cellular network, you have to install a 4G SIM card and\nturn on the cellular network first. The robot will connect to the Wi-Fi network first if both cellular\nand Wi-Fi networks are available. If the Wi-Fi signal is weak, the robot will automatically switch\nto the cellular network instead.\n3.4.2.1 Install a SIM Card\nStep 1 Remove the cover of the SIM card slot with a hex key.\nStep 2 Insert a SIM card and reinstall the cover.\n3.4.3 Turn on Cellular Network\nTurn on Cellular Network in the Settings > Network Settings interface. A 4G signal symbol will\nappear on the top bar.\nCaution\nOperations such as switching languages, importing music from mobile phones, and downloading pushed\nadvertisements must be performed under a Wi-Fi network.\n3.5 Auto Charging\nKettyBot supports self-charging. If you have purchased a charging pile and have set up the pile's\nlocation during mapping, when the battery level of the robot falls below 10%, it will automatically\nreturn to the charging pile after the current task is completed. You may also tap Charge Now on\nthe screen to return the robot to the charging pile for charging.\nKettyBot Pro Operation Guide\nVersion: V9.9 Operation Guide\n41\nNote\nThe charging pile is an optional accessory and can be purchased separately.\n3.6 Docking Instructions\nKettyBot supports three docking modes. In actual scenarios where multiple robots cooperate, users\ncan select any docking mode during mapping. This section only covers the description of the three\ndocking modes. For details about mapping, please contact our technical engineers.\nThree docking modes:\nOne-to-one Docking mode: Each robot has its fixed pickup location (docking location).\nFree Docking mode: Set multiple pickup locations (docking locations) for the robot to\ndock by priority, i.e., the robot chooses the nearest pickup location for docking.\nWaiting mode: Set temporary docking location. When the robot has no task and there's\nno vacancy at the pickup locations (docking locations), the robot docks at the temporary\ndocking location. Once a vacancy appears at a pickup location (docking location), the\nrobot automatically goes there for docking.\nKettyBot Pro Operation Guide\nVersion: V9.9 Operation Guide\n42\n4.
