Hi Buddy and All,

Here is a description of the keys on the HTX-212.  I hope this helps.

The three round buttons above the channel selector from left to right are:

VFO, MR and DUP.

Across the bottom from left to right are:

F, T/T SQL, DTMF, SHIFT, mHz, and CALL

The little round button next to the volume control is LOW and of course the
power button on the upper right.

On the microphone the buttons across the top from left to right are:

VFO, MR, mHz, and CALL

There are no other button assignments on the mic.

I hope that helps Buddy and good luck.  These are a mighty fine radio for
the low cost.  73

Kevin, K7RX :)
