3) LED indication
When the annunciator Nos. in SD64 to 79 all turn OFF, the LED (refer to (5)(b)
in this section), which was turned ON as the annunciator turned ON, turns
OFF.
POINT
If the LEDR instruction is executed when annunciator ON and the operation con-
tinuation error having higher priority (
occur simultaneously, the LEDR instruction clears the error having higher priority
( Section 6.21.2) than the annunciator.
Hence, the annunciator cannot be turned OFF if the LEDR instruction is executed.
When using the LEDR instruction to turn OFF the annunciator, execute the LEDR
instruction after removing the cause of the error having higher priority than the

The Basic model QCPU cannot use the LEDR instruction.
