4 Detailed Reference
Description of Ultrasound Modes
The application of ultrasound power may be fixed or linear. Linear power is proportionally controlled by the
footpedal between zero and the maximum limit set on the console.
Ultrasound power may be adjusted from 0% to 100% in 5% increments using the up/down spin buttons, Foot
Control buttons, or remote, and 1% increments using the keypad. The ultrasound output will be activated at the
minimum programmed power level as the footpedal moves into the active ultrasound region, and will increase to
the maximum programmed output as a function of linear footpedal travel.
Single Linear Ultrasound Mode with Fixed Aspiration
Once irrigation has been initiated and the footpedal has been depressed approximately five degrees (or as
programmed), an increase in footpedal resistance will be noted signifying the transition from Region 1 to
Region 2 and the start of aspiration. Fixed aspiration will be developed at the selected aspiration level. The
screen will display the actual amount of aspiration at any given time.
Ultrasound power is activated in Region 3 of footpedal travel. Another momentary increase in footpedal
resistance will be noted (if detents are enabled) signifying the transition from one Region to the next, and the
start of ultrasound power. Ultrasound power will be initiated and controlled as a function of footpedal travel in
Region 3. The next ultrasound submode may be selected (if enabled) by moving the footpedal in the outward
yaw direction.
Single Linear Ultrasound Mode with Linear Aspiration
Once irrigation has been initiated and the footpedal has been depressed approximately five degrees (or as
programmed), an increase in footpedal resistance will be noted signifying the transition from Region 1 to
Region 2 and the start of aspiration. Aspiration will increase from 0 to the fixed level in proportion to footpedal
travel in Region 2. The screen will display the actual amount of aspiration. Aspiration will remain at the fixed
level in Region 3.
Ultrasound power is activated in Region 3 of footpedal travel. Another momentary increase in footpedal
resistance will be noted signifying the transition from one region to the next, and the start of ultrasound power.
Linear ultrasound power will be initiated and controlled as a linear function of footpedal travel in Region 3.
Pulsed ultrasound may be toggled on/off by moving the footpedal in the outward yaw direction.
Note:
4-22
If single or multiple burst mode is selected, position 3 (or outward yaw movement) does not
control ultrasound power, but rather the burst interval (for multiple burst) or nearly full travel
initiates and resets the single burst (see page 4-23).
