### NAVTEX Operational Features

When a NAVTEX message is received, a notification will appear in the notification area.

Viewing received messages:

| Menu path |
|-------------|
| {{ menu }} → {{ settings }} → {{ menu_navtex }} |

A list of all messages received from the NAVTEX receiver will open.

```{note}
**Limitations:**

- ECDIS does not control the volume of stored messages.
- ECDIS does not filter messages by coverage areas.
- The navigator must independently filter incoming messages by transmitting station and type, depending on prevailing circumstances and conditions.
```

| No. | Description |
|:---:|---|
| **1** | Message reception time; |
| **2** | Identifier of the station that transmitted the message; |
| **3** | Type of received message; |
| **4** | Number of messages in a composite (long) message; |
| **5** | Frequency on which the message was transmitted; |
| **6** | Status of the message received from the receiver; |
| **7** | Delete message; |
| **8** | Message not viewed; |
| **9** | Message viewed; |
| **10** | Table filtration by transmitting station<br><br>![](images/image525.png) |
| **11** | Table filtration by type of received messages:<br><br>![](images/image526.png) |
| **12** | Table filtration by frequency on which messages were received:<br><br>![](images/image527.png) |
| **13** | Delete all — button to delete all messages in the table.<br><br>![](images/image528.png) |

```{important}
Data filtration in the message table does not affect the filtration of data received from the NAVTEX receiver.

ECDIS receives all messages transmitted by the NAVTEX receiver.
```

To view the message text — click on the message row in the table.

| No. | Description |
|:---:|---|
| **1** | Message text field. The message is displayed "as is" in the field; ECDIS does not correct or analyze the message text; |
| **2** | **Add user object** — button to go to the {doc}`user objects </sections/instruments/user-objects/index>` creation window; |
| **3** | **Back** — return to the list of received messages; |

Plotting objects on the chart is performed using {doc}`user objects </sections/instruments/user-objects/index>` tools.

```{note}
To plot **Mariner's objects**, the **Mariner's objects** option must be enabled.
```

Select the object type corresponding to the nature of the navigation warning (point, area, circle, etc.).

| No. | Description |
|:---:|---|
| **1** | **Coordinates to UO** — button to transfer recognized coordinates from the message to User Objects. If coordinates are not fully recognized, only recognized coordinate pairs will be transferred to UO; unrecognized values can be entered manually by the navigator. If coordinates are not recognized, a notification will be displayed in the message window:<br><br>![](images/image532.png)<br><br>When transferring coordinates, note that for a point object, select Point geometry; for an area object, select Area; for a circle, select Circle geometry; |
| **2** | **Info to UO** — button to transfer additional object information to UO.<br><br>If the selected object lacks an information attribute, a notification will be displayed in the message window:<br><br>![](images/image533.png) |
| **3** | Message text. |

```{important}
The reason for the inability to recognize object coordinates in a received message depends not only on reception quality but also on the coordinate notation format. The coordinate notation format is not formalized in the standard.

If a situation arises where data can be read but ECDIS did not recognize the coordinates, take a photograph or screenshot of the screen and send a notification to the ECDIS manufacturer by completing the {doc}`form </sections/bug-report/form-filling/index>`.

The ECDIS manufacturer will add the new coordinate format, release a software update, and send it to your address.
```

```{hint}
Object coordinates can be corrected:
 - in the message text window when plotting the object;
 - in the user object coordinate input fields.
```

After saving the UO, the resulting object will be displayed on the chart.
