Pressing the MENU key opens the pseudo menu item
00 MENU. Then after pressing UP or DOWN, it's going to select the item that was opened when you closed the menu the last time.

* Use MENU, UP and DOWN to select the value.
** Use 7 and 9 for navigation through digits, UP and DOWN (or selection knob) to choose characters.
Some functions only apply to a channel. Once you switch channels, or you switch from A to B, the menu item will change. If you're in frequency mode, the value stays the same even if you change the frequency. However A and B is still going to be different.
To save a frequency to a channel, long-press VM/SCAN, then choose the desired channel number. If the channel number blinks, it's vacant. Finally confirm with VM/SCAN, MENU or AB⏎. Delete channels by long-pressing FM.
There are 99 positions available and 16 positions in the FM Radio mode.
Under the PTT button, there are two other buttons with dots on them.
Button 2 (the top one) temporarily disables squelch, i.e. monitors the frequency regardless the quality of the signal. When tapped, it also switches display backlight on and off. Button 1 (the bottom one) seems to do absolutely nothing.
After pressing MENU and then VM/SCAN, the radio will start scanning either frequencies or channels (depending on current mode). Once it finds a signal, it does one of the following, depending on scanning mode (menu option 23 SCANM):
Stop the scanning with MENU or VM/SCAN. You can also switch the scanning direction with UP and DOWN keys or with the knob.
Works pretty much like the "normal" mode. There are 16 positions for FM channels, see Storing and deleting channels for how to use them.
Frequencies go from 65 MHz (!) up to 108 MHz. Frequency step for FM radio is always 100kHz.
Note that if there is signal from the "normal" mode, FM radio will be interrupted.
Turn the radio off, press and hold MENU (not FM as the manual suggests), then turn the radio on. A menu will apear:
|Model||What's next to the volume knob||Everything else|
|UV-B5||Selection knob||Same as UV-B6|
|UV-B6||Flashlight||Same as UV-B5|
