First, you will need the Paralinx Manager tool found here. The page also includes instructions for flashing firmware.
***If your Paralinx Manager does not detect your device on Windows, download and install the Teradek Bolt manager here. Afterwards, your Paralinx Manager should properly detect your device.***
Once you have Paralinx Manager installed, please follow the steps below
1. Open Paralinx Manager, go to status, click send message, and enter 'storagerestore' (without quotes). This can be done on both transmitter (Tx) and receiver (Rx).
2. Go to Settings, Select Region, and set the Region to the correct one for your area. Even if it seems to be set already, set it again.
3. Update radio 1 on the device. For good measure, this update can be run 2-3 times to ensure the firmware was written properly.
4. Power cycle everything.
5. Pair your devices.
