On some dental tables with vacuum dust collector, the motor may be used while being coupled 
with a dust collector. When such a dust collector * is used, power consumption of ULTIMATE

with a vacuum dust collector, select the mode as follows: 
 
How to select the mode 
While pressing      Forward/Reverse Selector Switch, turn on      Power Switch, and the mode 
can be selected. A long beep indicates vacuum-coupled mode and 2 short beeps indicate 
non-coupled (energy-saving) mode. 
 
* Each time the switch selection is made, the mode changes between vacuum-coupled mode 
and non-coupled mode. 
* A currently known dust collector is KAVO EWL-560.
