Here a the things to check if you locator does not show a location:
Verify that your Hub is working properly to make sure your have network coverage
Check the four lights of the Hub as shown in the picture below. From right to left: (1) The power indicator. This should always been green once the Hub is powered and has booted up completely. (2) The WiFi indicator. This light might be orange if the WiFi is not yet password protected, e.g. if the Hub has not been set up via the app yet. In all other cases, it should be green. (3) The LoRa light indicates if the Hub is connected to the Tabs LoRa network. This light must be green. (4) The Internet indicator. This should be green indicating that the Hub is connected to the Internet.
In summary, once you have configured your WiFi network, all lights should be green indicating that the Hub operates normally.
Verify the locator is charged and activated
First, make sure the locator is charged sufficiently. Connect the USB-C charging cable to the locator for charging. The charging port is located under the grey rubber cap in case of the object locator. The wristband has a white rubber cap.
Furthermore, make sure the locator is activated by briefly pressing its button (any of the two buttons in case of the wristband). The light should then flash twice with a few seconds in between.
If it does not flash, then the locator might be deactivated. In general, the locator can be deactivated or activated by pressing the button for at least 10 seconds. Your may want to use this feature before going on a flight.
If the locator appears to be deactivated, then press the button for 10 seconds to activate it. The light should flash very quickly when releasing the button indicating that the device has changed its state. Now, it should be active an briefly pressing the button should result in the light blinking twice as describe above.
The locator uses the Global Positioning System (GPS) to determine its location. For this to work properly, it has to be outside with partial of full sky view. Furthermore, the locator only starts sending frequent position updates if it is in motion. Therefore, for testing the locator take it outside and go for a walk. Give it some time to acquire the GPS signal and it should send its position to the mobile app.
Tabs mobile app considerations
Note that the locator sends updates to the mobile app even if it is unable to determine its position. For example, if it is indoor and cannot acquire the GPS signal. These messages are displayed in the mobile app without a position (only with a "-" indicating that the current position is unknown). Additionally, a red GPS signal icon indicates that the locator has checked-in without a valid GPS position.
