# Radio

The Radio menu allows you to perform a channel radio availability scan for each of the available channels.

If the area has a dense coverage of sensors from other base stations, this can become important.

{% hint style="info" %}
If sensors are already paired to the base station they will also show up as
 interference in the radio scan of the channel currently in use.
{% endhint %}

A channel scan can be activated for a selected channel or all channels at the same time. A scan takes 60
 minutes per channel during which it is not possible to pair new sensors to the base station or change the
 time of the device. Channel switching is disabled during the scan. Some data may be lost during the
 scanning period.

You can abort the scan process by selecting STOP SCAN. The statistics of the scanned channel in this
 case will be lost.

After the scan, we recommend choosing the channel with the highest availability to ensure that you receive
 a reliable data stream from the sensors and avoid data loss.

{% hint style="warning" %}
When changing the channel, already paired sensors require re-pairing.
{% endhint %}

## 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://help.aranet.com/base-stations/base-stations/web-interface/overview/system/radio.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.
