N5R-20 / N5R-30
    Keypad Beep  (Menu 8)
        When set to OFF, receiver audio is muted.
        Setting  MENU 8 back to ON returns audio to normal.
        This does not affect any other function of the radio.
        Only the Keypad Beep.      DETAILS

    Battery Level indicator added
        Pressing the ZERO key displays the battery voltage level

    Entering the 7th / 8th frequency digit is now predicted.
        The is no longer required.
        The Step setting now only impacts scanning.
 
    Cloning capability has been removed.
 
    Scanning for CTCSS and DCS tones require that Menu 10 (DCS) or Menu 11 (CTCSS) need to be set to something other than OFF to perform the scan.
 
 
N5R-213 / N5R-313   (Sept 2014)
    Keypad Beep  issue resolved

2 power levels

N5R-2x
N5R-2xx
N5R2xxx
3 power levels

N5R-3x
N5R-3xx
N5R3xxx

HN5RV011
HSN5RV01
F5R3407


Note: 
 
N5R2401 is from a radio with 2 power levels (a UV-5R variant)
N5R3409 is from a radio with 3 power levels (a BF-F8HP variant)

The BEEP bug was the last known user detectable bug a UV-5R variant. It was introduced with the N5R-20 firmware back in the summer of 2014 .

It was fixed in September of 2014. As long as the radios have one of the N5R2xxx or N5R3xxx firmware versions, you aren't going to notice any difference between firmware versions.
