Motor Speed versus File Speed-The torque and speed output are exactly the same between the Sequence and Sequence II. - Original EndoSequence measures the speed of the motor on the display panel- EndoSequence II measures the speed of the file on the display panel- When energy is transferred from the motor, through the head there will be a loss of energy. This means that while the motor is turning at a certain speed (Eg. 10,000 rpms) the file doesn’t actually turn at that exact speed divided by 10 (1,000 rpms). - The EndoSequence II corrects the loss by measuring file speed, not motor speed - If you were to compare the two models side by side the Sequence II would show the speed at 900 while the original Sequence would show a speed of 1,000 – even though both files are turning at the same speed. -Imagine two cars are racing neck and neck. One car is being measured in miles per hour while the other is be measured by the rotations of the tire. The cars are traveling at the same speed just being measured differently.

Basic Cordless Set-up


Changing the Head

• The contra angle head can be connected with the motor handpiece at 6 adjustable head positions.

• Align the positioning pins of the contra angle head with the positioning slots of the motor handpiece and insert the head until they click.

• When removing the contra angle head, pull straight out.

• The heads are compatible with original EndoSequence and EndoMate DT systems.


Placing and Removing the File

Placing the FileInsert file into contra angle head and twist until the file locks with the chucking mechanismTip: The push button does not need to be depressed to seat the file as you would in a highspeed handpiece.

Removing the FileDepress the push button and pull out the file


Setting the Torque

Turn Power OnThe Power is turned on by simply holding the Power Key down for 1 second.

Setting the Torque- Depress the “S” or Select Key once. (The speed readout will disappear and the torque setting will be displayed).- Now press the Up/Down Key until the desired torque level is reached. (Alarm sounds if the set value exceeds the upper limit or lower limit.)- Press the Select Key again to change another setting like speed or simply press the On/Off Key to begin using the file


Setting the Speed


Setting the Speed- The EndoSequence II Program is always defaulted to the speed setting.- Simply press the Up/Down Key until the desired speed level is reached. (Alarm sounds if the set value exceeds the upper limit or lower limit.)- The Speed setting can be adjusted during file operation by pressing the Up/Down Key.


Setting the Head Gear Ratio


Setting the Head Gear Ratio- Depress the “S” or Select Key twice. (The speed and torque readout will disappear and the gear ratio “GR” will be displayed).- Now press the Up/Down Key until the correct Gear Ratio is achieved(Choice between 4:1, 10:1, 16:1, & 20:1)- Press the Select Key again to change another setting like speed or simply press the On/Off Key to begin using the file


Understanding the Auto Reverse/Stop Features

- One important feature with the EndoSequence II Cordless is the ability to set torque limits.- As with so many facets in dentistry certain parameters are in place to protect the user and/or the patient. Torque limits are in place to prevent undue stress on the file that can cause separation.- The EndoSequence II has a feature that when the torque level is reached the file automatically reverses out of the tooth so the pressure or load on the file is reduced.- The next three slides will explain how the process works


Understanding the Auto Reverse Feature

- When the torque limit is set, the file runs in the forward direction when operating at torque levels lower than the set limit.- When the load on the file reaches the torque limit, the files stops spinning in a forward rotation and instead rotates in reverse.- When a load is removed, the file returns to normal rotation (forward rotation) automatically.


Understanding the Auto Stop Feature

- When the torque limit is set, the file runs in the forward direction when operating at torque levels lower than the set limit.- When the load on the file reaches the torque limit, the files stops spinning in a forward rotation and instead rotates in reverse.- When the load is removed, the file stops automatically. In the Auto Reverse mode the file continues back in the forward direction. In Auto-Stop mode it comes to a complete stop once the load is removed through reverse rotation.-The user will need to press the on/off switch to start the file in forward rotation again.


Understanding the Auto Reverse OFF Feature

- When the torque limit is set, the file runs in the forward direction when operating at torque levels lower than the set limit.- When the load on the file reaches the torque limit, the files stops spinning in a forward rotation and comes to a complete stop (without reverse).- If you want it to rotate (forward-rotate) again, re-press the ON/OFF Key


Setting the Auto Reverse/Stop Feature

- While the motor is stopped, Hold the Select or “S” Key for 1 second or longer.- Continue holding even when you hear the “beep” and see the auto reverse mode flashing.- While holding the Select key, Press the Up/Down key until the desired mode is highlighted. (Now you can stop pressing the Select key).

Auto Reverse Auto Stop Auto Reverse OFF


Changing the Programs


Changing the Program- 5 Pre-Settings or Programs to choose from- Press the Program or “P” Key until the desired pre-set is reach (1-5 @ the top of the screen)

Setting the Program- Select the desired pre-set program (1-5)- Adjust the Torque, Speed, Gear Ratio and Auto Reverse according to your needs.- Hold the Program “P” Key down until a “beep” sounds. The desired levels are now set for the specific program.


Hand PlacementA common misconception is that the index finger

should rest on the on/off switch during operation (see figure 1). The EndoSequence II does have a feature that allows the finger to rest on the on/off switch and when lifted off, the file stops. This is done by holding the on/off switch for longer than one second.

To achieve the best control of the handpiece, increase tactile awareness and prevent increase pressure on the file it is recommended that the index finger rest on the head (similar to figure 2) rather than the on/off switch.

It is recommended that the up/down motion be controlled by the fingers – not the wrist

Calibrating the Motor

1. Lubricate the contra angle head with PANA SPRAY. 2. Turn on the power.3. Hold down UP/DOWN key simultaneously for more than one second.4. The LCD panel displays “CAL” with the alarm sound.5. Attach the contra angle head (without file) to the motor handpiece and

press the ON/OFF key. 6. If the motor handpiece begins to rotate, leave it as is until it stops.7. This process ends, if the rotation stops and the LCD panel display

returns to its original state.8. If you want to stop this process, turn off the power.

Over a period of time there can be a fluctuation between the speed of the motor and the difference in torque by the contra angle head. Periodically, the motor can be calibrated to make certain torque and speed levels are accurate.


Cleaning the Handpiece

Lubricate with Pana-Spray before each autoclaving.

1. Screw the F type spray nozzle onto the Pana-Spray nozzle.

2. Insert the F type spray nozzle into the rear part of the contra angle head and lubricate the head for 2-3 seconds.

3. Insert the head into an autoclave pouch and seal it.

4. Autoclavable up to a max. 135°C (275°F).

5. Keep the handpiece in the autoclave pouch to keep it clean until you use it.

Do not heat sterilize the motor handpiece.


Charging Sequence

1. Make sure the charging base Power Switch is on. Check that the power lamp lights up.

2. Insert the motor handpiece into the Battery Charge base. Charging starts with the charge mark flashing on LCD.

3. When the alarm sounds and “FUL ” is displayed on the LCD panel, charging is completed.

- Unlike the original EndoSequence this charging base does not have to be turned off/on or “reset” every time.

- Charging base does not work with original EndoSequence Cordless

- Charging time is around 90 minutes


Replacing the Batteries• Remove the rubber cover from the battery cover with a thin flatblade screwdriver.

• Remove the screw fixing the battery cover with a Phillips screwdriver. (screw driver is not provided with the EndoSequence II)

• Remove the battery cover by sliding it toward the charging terminal.

• After removing old batteries, insert new batteries according to the polarity marking in the battery box.

• Attach the battery cover and tighten the screw with a Phillips screwdriver.

• Insert the rubber cover back into the screw hole of the battery cover


Alarm Sound Control

An Alarm will sound as the handpieces get close to the torque value limit. This feature can be turned off if this is preferred by the user.

1. Turn off the power2. While pressing SELECT key, keep pressing POWER key for 1-2 seconds (until the beep sound).3. Stop depressing POWER and SELECT Keys4. Press the SELECT key to select ON or OFF for alarm sound.5. Once the sound mode has been selected touch the POWER key to go back to the original screen.6. Display on the LCD screen will return to the original state if no operation is performed for a while.
