i can sometime access the option screen but not all the times

6. Press the Blue button to choose the NAGRA option
7. Four arrows back take 0X55'
8. One down arrow takes you to the 0x00 - i.e. Key 0. Press OK
9. Up pops the HEX Keyboard - just type in the new numbers - it puts the dots in for you. Do this for Key 01 as well.
