Impossible to get the good Frequency in the CDU (MD11)

Hi there everybody

I found nothing about my problem in this forum, so I star a new topic

:help:

Some thing goes wrong with my beautiful MD11

Sometime I have a strange problem, impossible to enter the radio frequency in the CDU. VOR and ILS

When I select 113.30 in the scratchpad I get in VOR 2 113.00? 113.30 the result is 113.00

Same problem with the ILS.

109.90/094 in scratchpad the result is 109.00/094.

.30=.00

.90=.00

If you know what exactly works wrong, please feedback the answer

Thanks, and sorry for my English

Best regard

Olivier
