Speed setting
When you pick up an electric motor, the programmed
speed of the motor in RPM (revolutions per minute)
appears on the display.
You can set the speed with the quick adjustment keys on
the left side of the dentist element control panel.
If the cursor is in the intensity setting block, then the
speed can also be set with the foot switch with cursor
forwards/back.
When you press the corresponding key briefly (< 0.5 s)
then the value in RPM (min

vant key appears on the display:
When the speed is set with the cursor, the displayed
value is incremented/decremented in steps of 10000
when actuating the foot switch briefly (< 1 s) forwards or
back.
At the values of 200, 20000, 40000, the green LED in the
corresponding key lights up.
When you press and hold down a key for > 0.5 s, you
adjust the speed in predefined increments:

shown on the display for > 0.5 s, the speed is reduced.
