Flipper Zero’s sub-1 GHz module is capable of receiving signals at all frequencies in the 300-348 MHz, 387-464 MHz, and 779-928 MHz operational bands. However, **Flipper Zero transmits signals only at frequencies that are allowed for civilian use**.
On this page, you’ll learn more about how signal transmission works in your Flipper Zero, and find a list of frequencies allowed for civilian use in particular regions.
***
## How to determine your region and allowed frequencies
Flipper Zero has the send function disabled out of the box until the device is [updated](https://docs.flipper.net/zero/basics/firmware-update) either via **Flipper Mobile App** or **qFlipper** with a [microSD card](https://docs.flipper.net/zero/basics/sd-card) inserted. If you try to use the Sub-GHz function before updating Flipper Zero, you will see the following message: **Firmware update needed. Update the firmware before using this feature flipp.dev/upd**.
While updating Flipper Zero, the region where the device is located is determined and frequencies allowed for transmission in that region are unlocked. To see your region code in the [ISO format](https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes) while on the Desktop, **press and hold** the %down%**DOWN** button.

To learn more about regions and frequencies allowed for civilian use, see the table below:

To find out what frequency your remote control works at, use [Frequency Analyzer](https://docs.flipper.net/zero/sub-ghz/read#bwvDc).
If you try to send recorded signals at frequencies that are prohibited for civilian use in your region, you will see the following message: **Transmission is blocked. Transmission on this frequency is restricted in your region.**
