What does an EIU do?
EFIS/EICAS interface unit (EIU). What they do is monitor all airplane systems and control info displayed on both EICAS screens and EFIS.
In AUTO, what will an EIU do?
It defaults to EIU L. If that fails, it goes to EIU C. If that fails, it goes to EIU R.
In AUTO, an EIU can switch to another EIU if one fails. If you manually select any of them (L, C, R), will they switch if one fails?
No. Manual selection of an EIU means that automatic switching is inhibited.

1.) It cancels caution and advisory messages (when on the last page)
2.) It displays next page of messages if multiple pages exist
3.) It cancels the red box for an engine exceedance if no longer in that condition.
What does the RCL (recall) switch do?
-Displays all caution and advisory messages (if condition still exists) that you previously cancelled
-Redisplays red box for engine exceedances
-Displays first page of messages when multiple pages exist
