The following are important steps you should take before transmitting any messages. Make sure that you have flashed your device with Meshtastic and connected with a client before proceeding.

### Set Region

:::important
Make sure to set your `region` to the correct region so you don't transmit on an incorrect frequency.
:::

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.
