Bill, the only thing you have to do is:
With "band up" or "band down" go to the 40m-band.
Then tune down to 5,xxx MHz with the tuning knob.
Next step...with pushing "band up" you should be again on 40m.
The new "extra-band" should be now between the 80m- and the 40m-band.
If you don't tune out of any other ham-bands, the "extra-band" with 5,xxx
will remain there.
