Clear Memory/Message Queue
These options are found under Tools then Clear Display Memory and
Clear Display Message Queue. The clear memory option erases the
entire memory of the display. Memory Cleared is displayed and then
the display goes through a reset cycle. The clear message queue
option just erases the queue, not the display memory. If there is a
background message, it is displayed after a clear message queue
command has been issued.
