When the R/C is set as the sub R/C, IU unit selection cannot be made. All units will perform the up and down operation simultaneously.
�
When the suction grille comes to a stop at its prescribed position, the two wires may sag approximately 8 cm (max), and the suction grille may tilt, but this will be corrected automatically when the grille
retracts.
�
A loud sound may be heard due to this correction motion at the retraction position, but this does not indicate a failure of the unit.
�
When wire sag is detected due to the grille running over an obstacle, etc. the grille may not perform the up and down operation to avoid wires to get tangled. Remove the obstacle, tension the wires,
and press the

buttons again.
