The ICP and Mediablock are not a couple.

This means one of both has been replaced. You need to marry both. Start the clear security warning procedure. See "Authorization to clear security warning on the projector". Together with this error you will always have an error “imb - physical marriage tamper event”.

Brief procedure to clear the security warning:

1. Ensure the cover plate of the Light Processor compartment is properly installed.

2. Ensure that all boards in the Card Cage are properly installed.

3. Ensure that the top over of the Card Cage is properly installed.

4. Start up the projector.

5. Initiate authorization by holding the security key in the security socket (reference 1 image).

6. Enter the pin code within 5 seconds.
