The 2nd part of the setup requires Internet access. Please ensure that your device (tablet/phone) is connected (back) to your location's WiFi.
Alternatively, you may perform WiFi setup by connecting your Watchman to a USB port on your PC. It is similar to downloading a program on PC to configure a new device.
Please look for "Watchman Online" in the app store. App provides an easy access to all your Watchman units and their logs.
