## Overview

Channel settings are an integral part of the way your devices communicate across the mesh. If you have mismatched channel settings, your radios will be unable to communicate with one another.

## Settings

<!--- TODO add other channel settings --->

| Setting | Acceptable Values | Default |
| :-----: | :---------------: | :-----: |
| region | `Unset`, `US`, `EU433`, `EU865`, `CN`, `JP`, `ANZ`, `KR`, `TW`, `RU` | `Unset` |

### region

The `region` variable sets which region your radio is configured to work in. It is important to ensure that you've set it to the correct region. If left `Unset`, it will default to `US` settings.
