Chapter 4 Firmware Upgrade

4.1 Firmware Version

The firmware version can be checked through mobile phone or computer, and you can judge
whether it is necessary to upgrade the firmware according to the current T8FB version number.
Since T8FB was updated multiple versions before, the new firmware is not fit for all versions of
T8FB. Therefore, please check your current firmware version before upgrading the firmware. If the
firmware is not necessary and the T8FB transmitter can be used normally, then there is no need to
upgrade. You also need to confirm if your T8FB is OTG version or BT version.
If it is T8FB (OTG), please download the latest firmware from the link:

If it is T8FB (OTG), please download the latest firmware from the link:

Since there are many updates for T8FB, and not all T8FB is compatible to the latest firmware on
the official website. Be sure to choose the suitable
firmware for your T8FB. Please distinguish whether your
T8FB is an OTG version or BT version before you update
the firmware. Refer to the following picture, the word BT
next to the T8FB model means it is the BT Bluetooth
version, and it is the OTG version if there is no word BT.
Check the picture on the right for reference. If you
cannot confirm it is OTG version or BT version, please
contact RadioLink after-sales for confirmation.
