4-6-5 Clearing Error Messages
After the I/O table has been registered, any error messages recorded in memory
should be cleared. It is assumed here that the causes of any of the errors for
which error messages appear have already been taken care of. If the beeper
sounds when an attempt is made to clear an error message, eliminate the cause
of the error, and then clear the error message (refer to Section 9 Troubleshoot-
ing).
To display any recorded error messages, press CLR, FUN, and then MONTR.
The first message will appear. Pressing MONTR again will clear the present
message and display the next error message. Continue pressing MONTR until
all messages have been cleared.
Although error messages for fatal errors can be accessed in any mode, they can
be cleared only in PROGRAM mode.

4-6-6 Verifying the I/O Table
The I/O Table Verification operation is used to check the I/O table registered in
memory to see if it matches the actual sequence of I/O Units mounted. The first
inconsistency discovered will be displayed as shown below. Every subsequent
pressing of VER displays the next inconsistency.
Note This operation can be executed only when the I/O table has been registered.
