The "WX" indicator on the display is not for weather band. It allows arbitrary receive and transmit frequency pairs as described in the manual (F+Led button). I'm not sure why it ended-up as "WX" on the display.
The APO indicator (bottom middle) has no function whatsoever.
Keypad sound (bell symbol in top right) is always on. I've not found any way to turn off the keypad beep.
Overall, the display is great because there's none of the short-cuts of left-off digits anywhere. All significant digits of the entire frequency (8 digits) or memory channel (2.5 digits) are shown under all circumstances. Very nice.
