Operation

Operation/
Procedure

1. The names of the loads which can be operated are displayed. Select the load to be checked with the key, and the

selected load is highlighted.

2. Press the [EXECUTE] key.

The load selected in procedure 1 starts the operation. During the operation of the load, the [EXECUTE] key is
highlighted. If the EXECUTE key is pressed while it is highlighted, the operation is stopped.
When two or more operations are selected in procedure 1, the operation is performed in the sequence of display
order.
