I have today been entering new BISS/CW codes thru the 8280 menu - one entry was fine - channel cleared - the second which ended in 8C did not clear the channel. I returned to the menu to see that the entry read 8F - I thought I had just made a date entry error - so reentered that field to 8C - save the settings - channel not cleared - checked menu - still 8F !! I then zeroed the line and saved - all zeros OK - re-entered the line and saved - guess what 8F again - tried on a different line and still this error occurs - entering 8C gets saved as 8F !!
I have firmware 128 + phantom131p and addon_2

All other aspects of the box are fine, other BISS keys are fine and the 8281 menu works OK as well.

Can anyone shed some light of this anomaly ??

thanks
