Please perform a firmware upgrade. The query function for entering the PIN was incorrect and was revised. As of firmware version 02.44 this works flawlessly. How to perform a firmware upgrade, please read here: Firmware Upgrade

Note: For some CI modules it’s possible, the PIN query generally to suppress. This can be useful, though generally not for persons under 18 residing in your household.

Go to the CI module  menu. (menu -> Conditional Access) and take the appropriate setting. Please follow the instructions of the CI module manufacturer because we do not support them.
