DDR 0 & 1 Not Found
There is a problem with the switcher DDR 
memory. The switcher may be used but 
many features will be limited or disabled
Re-start your switcher. If the problem 
persists, contact Ross Video Technical 
Support for assistance.
Panel/Frame Mismatch
Your switcher control panel is connected 
to the wrong frame type (e.g. Crossover 16 
panel connected to a Crossover 6 frame).
Connect your switcher control panel to 
the proper frame and re-start the switcher.
Upgrade PMC?
Your switcher requires a Panel Module 
Controller (PMC) upgrade as part of a 
software upgrade. The switcher may be 
used without the PMC upgrade but may 
respond in an unpredictable manner
Allow the PMC upgrade to proceed. 
Contact Ross Video Technical Support 
for assistance if you are unsure about 
upgrading your switcher.
