Note 1. Do not assign the same unit no. as one of the other Special I/O Units to
the Voice Unit; unit no. duplication results in an “I/O UNIT OVER” error.
2. If the message output mode is changed after creating the I/O table,
because the number of allocated words is different, an “I/O SETTING
ERROR” will be generated. In this case, re-create the I/O table.
