Upon completion, the wizard will send a "guest request" to the boat owner for confirmation. After the request is accepted you will be able to start using the application.

The activation code is embedded within the QR code. It may also be found written under the QR code in numeric (textual) format. The serial number (SN) can be found on the front face of the device.

The device should be positioned such that the QR code faces upward. Do not place the device under metal enclosures.

You may have activated the "boat lock" or "anchor alarm" functionality, and the Sentinel service is warning you that your boat has moved from its initial position.

One of the following may be happening:

• The device has not yet started sending data to the server. In some cases, it may take up to 15 minutes after the device is activated and turned on for the first data point to appear.
• The device may not be connected to an Internet network.
• The SIM card is not yet activated. Please contact Sentinel support.

Please verify that:

• You are properly connected to internet (WiFi, 3G or 4G)
• You are using correct credentials (username and password)

If you don't have a Door sensor installed, disable it in the application. In the mobile application open the affected boat, open the Sensors tab and click the "Edit" button. From there you can hide the Door sensor.

The device has not yet started sending data to the Sentinel server. In some cases it may take up to 15 minutes to receive the first data point after powering on the device and creating an account.

The device will store the captured data (routes, battery status, alarms, etc) on the device until internet connection is secured. Then, the data will be uploaded and you will be able to see it in the Sentinel apps.

Please contact the Sentinel technical support (Sentinel d.o.o., GSM: +385/91/33 55 66 7)

The serial number is not the same as the activation code. The activation code is written just beneath the QR code in a small font size.

You may be in an area without mobile Internet coverage (3G or 4G - LTE). The information will appear on your device when strong mobile signal is available.

Due to the sampling frequency it may occur that the route is occasionally drawn over land. If this occurs frequently, please inform the Sentinel technical support (Sentinel d.o.o., GSM: 00385 91 33 55 66 7).
