You are right, I just tried it and only holding the function 
button is necessary to lock and unlock the rig.  Jim WA6EKS

I think that pressing in and holding the function button locks 
the front
pannel.  Try that! Doug, N6NFF

Butch, you are right about that.  Thanks, now both VFO's are the
same volume as before.  I guess the lock function is a good one
as well.  I wonder if there's a lock function that locks the
front panel yet still allows you to transmit? 73, Jim WA6EKS

Here is what I have in my notes.

OnI thought this was a menu choice, but it is not.  To mute or
attenuate
the band you're not using press function low to turn this mode on
or off.
If I remember right, you press function then low, not at the same
time.  I
just tried it on my radio, press function then press transmit
power
button, this will put other vfo at about half volume while
transmitting
and receiving on main one.  Doing this again puts it back to
normal.

Tom, pressing the function button and transmit power button
locks
and fortunately unlocks the radio.  Oh, it even keeps it from
transmitting.  Never knew about that function, but it doesn't
unmute or mute either of the VFO's.  Wow, you learn something
new
everyday.  I have been reading the 590 manual again.  Guess I
need to read the 71a manual as well.  73, Jim

Jim:

If you don't want the receive on the second VFO to be muted
while
using the
dominant VFO, press the function key, plus the TX power button
till you hear
the low beep.  The TX power button is the third one in from the
two VFO and
squelch controls.

Does this help?

Hello list, I am having a strange thing happen on my 71a which I
must have
caused but can't figure out how to undo.  When I am listening on
my 71a,
and have the right VFO on a memory either VHF or UHF and the
left
VFO on a
different memory, and have both squelch knobs turned off, the
memory that is
selected will dominate, meaning that if I turn the volume of the
dominant
VFO up it will mute the squelch sound of VFO b.  The opposite
also hapmens.
I know that it is possible to have both VFO's work at the same
time without
either one being muted unless you transmit on one and the other
is listening
on the same band.  Does that make any sense? The mute button,
righthand most
button on the bottum row,  will select between a and b VFO but
when both are
supposed to be active, they are not.  I don't know how to
explain
this any
better, but maybe one of you TMV71A owners will know what I'm
talking about.
