It's not the kind of password you set yourself, but one that's written in the manual, saying to press and hold the F key plus the power button to enter, which would require a 6-digit password. However, I didn't find it, and I also don't want to transmit on a different frequency. I just wanted to see what the interface looked like. I searched many websites but couldn't find any related information. Could someone please provide me with the password? Thank you.
