# Important Notice

1. For optimal performance, use the included original power adapter. If unavailable, use any safety-certified **5V3A** (for iSG Display) / **5V2A** (for iSG Box) adapter with the appropriate cable.
2. Both iSG Display and iSG Box DO NOT contain batteries, so ensure a **constant power supply**.
3. To log in, iSG needs an internet connection. After that, it operates locally without internet, though some Home Assistant integrations, like Tuya, may still require it.
4. Default Home Assistant credentials (built-in): **admin / admin**. You can change it later in Home Assistant settings.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kb.linknlink.com/isg/getting-started/welcome/important-notice.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
