The "B" in Leitner Wireless Serial Numbers

If you flip over your Leitner wireless headset base and read the serial number, you may find that there is a "B" in there, but maybe not.

In case you are wondering, the "B" means you have a new software version. The main change is that you can now move into computer mode even if the USB cord isn't plugged in. In previous versions you couldn't do that, so something new!

So now you know!
