Dual Operator Mode (A/B)
The dual operator mode on the deluxe touchpad provides additional programmable positions for a second operator.To program the delivery
system for two operators, first select the operator mode being programmed (A/B).A letter in the lower left corner of the touchpad screen will
appear showing the active mode. Program the appropriate function.

•Press and hold Program and A/B together until the touchpad switches to ”select handpiece.”
• Activate the handpiece being configured, and follow the steps displayed on the touchpad screen.
Programming Memory
The memory settings (M1-M4) are different for both operator A and B modes and for each handpiece position. All memory settings are factory
preset with both the air and water coolant on.
Electric Micromotor
When activated, the desired maximum RPM can be programmed into one of the four pre-programmed memory settings. To adjust the RPM limit,
use Plus (+) and Minus (-). Select water and air coolant to be on or off, and press Program and the Memory button (m1-m4). Three beeps
confirms the setting. The total range is 300-40,000 RPM. An RPM limit bar shows the RPM level for the electric micromotor.
EXAMPLE: If the RPM limit is set for 40,000 RPM and the power limit bar shows half, then the electric micromotor is operating at
approximately 20,000 RPM.
The maximum RPM limits are preset to the following:
Preset Maximum RPM
m1
2,000
m2
10,000
m3
20,000
m4
40,000

beeps confirms the setting. A power limit bar shows the power level to the scaler.
EXAMPLE: If the power limit is set for 50 percent and the bar shows half, then the scaler is operating at approximately 25 percent power.
The maximum power level limits are preset to the following:
Preset Power Level Limit
m1
25%
m2
50%
m3
75%
m4
100%
NOTE: When the deluxe touchpad displays zero percent, the scaler continues to operate at minimum power causing tip movement.
WARNING: Do not attempt to change the scaler tips when the unit is operating.
