### Preparation for Update

**NSR ECDIS NES-3000 software update** is performed using a **USB medium** containing an archive with updates released by the software developer or from the ECDIS software manufacturer's repository.

```{important}
**Information about software updates** is available at:
- <span style="color:red">**NSE DOMAIN NAME**</span>

**Onboard system software updates** are performed by authorized dealers of **NEW SUNRISE CO., LTD**.
```

```{important}
**Before updating the software**, perform {doc}`USB medium mounting </sections/system-settings/media-devices/index>`
```

### Update Search Logic
 1. First, ECDIS searches for updates on the removable medium.
 2. If no medium is present, the search is performed in the repository.
 3. If a medium is found and an update package is detected on it, the software checks the update relevance.
 4. After checking update relevance, a comparison is made with the update in the repository.
 5. The latest relevant update is installed.

```{attention}
To update the software from the repository, Internet access must be provided.

When configuring the bridge network, the repository address must be added to the list of **trusted** addresses.
```

### Update Procedure

```{warning}
Do not interrupt the update process before it is fully complete. This may result in system corruption.
```

```{important}
**If the software update completes incorrectly**, contact an authorized dealer of **NEW SUNRISE CO., LTD**.
```

```{important}
**Update failure** — Before starting the ECDIS software update, ensure that the correct time is set in ECDIS. If the ECDIS date and time are earlier than the update package release date, the application will not install the updates.
```
