Advanced Operation Functions
- Cont’d
Forward/Reverse Selector (FWD/REV):
Determines the rotation direction of the handpiece.
The LED on the Fwd/Rev button illuminates green when forward rotation is selected. The
red LED on the Fwd/Rev button indicates reverse rotation. When the Reverse Beeper
feature is activated, an audible beep (and the red LED light) will indicate reverse rotation.
Torque Controls
Torque Up/Down Buttons
Allows the user to adjust exact torque limits in Newton•Centimeter increments (in Implant Mode) and
Gram•Centimeter increments (in Endo Mode) .
Depress the Torque Selector Up/Down buttons until
the desired torque level is indicated on the LCD Display.
Maximum Torque Button (MAX):
The VCT allows the user to change the characteristics of motor operation for different procedures
and torque requirements. Press and release the MAX button to change the settings as listed below.
NOTE: Characteristics change depending on the selected mode, Endo or Implant.
Implant Mode
LED Off
– The VCT will limit operation at the selected torque level.
LED Green
– The VCT will stop at the selected torque level for one second.
This is the suggested setting when tapping and threading implants.
LED Red
– Max torque is activated, the VCT will operate at full torque. This is the suggested setting
for an osteotomy, or surgical site preparation.
Endo Mode
LED Off
– The VCT will limit operation to the selected torque level.
LED Green
– The VCT will Auto-Stop Reverse at the selected torque level. This is the suggested
setting when using NiTi rotary endo files.
LED Red
– Max torque is activated, the VCT will operate at full torque. This is the suggested setting
for gaining access to the canal.
Implant Mode:
By adjusting the torque control to higher limits at lower rpm, setting the implant is quick and easy.
Max torque during the osteotomy ensures more than enough torque for drilling purposes.
Torque settings are retained in memory even after unit is turned off.
Proper contra angle maintenance, including cleaning and lubrication are essential to minimize torque losses
when using the torque reduction settings.
Endo Mode:
By adjusting the torque control to reduced limits for each instrument size and operating
the handpiece at a constant RPM, the risk of instrument breakage is greatly reduced.
