I stumbled on these two “hidden” settings on my Baofeng radio yesterday which I added to the Short Guide:

*

Short press to reverse repeater output and input

Long press to scan channels or frequencies

#

Short press to toggle between H/L power

Long press to lock the controls

From the MENU settings:

7.

TDR ON allows the radio to quickly scan between the A/B channels or frequencies.

8.

BEEP OFF turns of the beep when pressing buttons.

14.

VOICE OFF turns off the voice when pressing buttons.

21/22.

MDF-A/B sets how the channels / frequencies are displayed. I have one set to NAME and the other to FREQ.

39.

ROGER OFF turns off the roger beep. Please turn this off!

The other setting I recommend changing is the squelch levels using CHIRP. More info on how to do that on the Chirp How-to page.
