Hold down the file release button on the contra angle and insert the file. Turn the file back and forth until it is lined up with interior latch groove and slips into place.
Page 14: Attaching Foot Switch
Attaching Foot Switch Insert the foot switch plug all the way into its jack on the side of Foot Switch Plug OTR Module. [This jack is marked with a small triangle (►) pointing right.] • Always hold the connector to connect or disconnect cords. * Operate the handpiece with the foot switch if a canal cannot be accurately measured.
Page 15: Checking The Function
• Check the ROOT ZX II’s operation before each patient. If the indicators in the display do not all appear normally, the File Holder Contact instrument may not be able to make an accurate measurement.
Page 16: Operating The Unit
4. Operating the Unit • If there is a lightning storm while the battery is being charged, do not touch the main unit, the AC adapter or the main power cord; you could get a shock. • Stop using the instrument and have it repaired if the display does not appear properly or if the instrument suddenly turns off (except in the case where it automatically turns itself off after 10 minutes of not being used).
Page 17: Normal Mode
<Normal Mode> If the file torque is less than the set value, the file will keep rotating in the forward direction. When the file torque is more than the set value, the file will automatically start rotating in reverse direction. Furthermore, the Normal mode can set various motor controls as described below.
Page 18: Root Canal Measurement (Two Methods)
Root Canal Measurement (Two Methods) Plug the probe cord into Canal Measurement Module and connect the file holder and contrary electrode. Probe Cord Plug a: Detach the micromotor from handpiece cord. Select M1, M2 or M3 with pressing the MODE switch and measure length of a root canal.
Page 19: Preparing The Root Canal
Preparing the Root Canal Plug the handpiece cord into OTR Module and then connect the handpiece and the contra angle. Handpiece Cord Plug Press the MODE switch to select M1, M2, or M3, and then perform root canal Preparing. • Make sure that the contrary electrode, file holder, handpiece file electrode etc.

Liquid Crystal Display and Switches <OTR Mode> Battery Power Indicator Shows how much power is left. Canal Length Indicator Bar • Charge the battery as soon as the Torque Line indicator gets down to the last two bars. • Never use the unit when the battery If the file torque is more than the set Sound Volume power display is flashing.
Page 21: Torque Settings
Torque Settings • If the torque setting is too high, the file could jam inside the canal. • The torque settings must be changed depending on the root canal condition. • When the auto torque reverse seems to be triggered too frequently, or it is triggered immediately after starting the normal rotation, increase the torque setting by one line.
Page 22: Normal Mode
<Normal Mode> Battery Power Indicator Shows how much power is left. Motor Stopping Time for • Charge the battery as soon as the indicator Apical Reverse gets down to the last two bars. • 0, 0.25 ( ), 0.5 ( ), and 1 ( Never use the unit when the battery power second.
Page 23: Torque Settings
Torque Settings • If the torque limit is too high, the file could get jammed in the canal. In this case, set the micromotor for reverse rotation to free the file. (See page 27, “Reverse Rotation”) • When the torque reverse function is turned off, the file could be engaged in the root canal and lock up. When this happens, set the micromotor for reverse rotation to free the file.
Page 24: Setting Memories For Other Functions
Setting Memories for Other Functions <OTR Mode> To change the settings other than Torque Line, Apical Line or Rotation Speed, take the following steps. 1. Turn the power off. 2. Press the SELECT switch and turn the power back on without releasing the SELECT switch. 3.
Page 25: Normal Mode
<Normal Mode> To change the settings other than Torque Line, Apical Line or Rotation Speed, take the following steps. 1. Turn the power off. 2. Press the SELECT switch and turn the power back on without releasing the SELECT switch. 3.
Page 26: Meter Display
Factory Settings for Memories Memory Item Mode OTR Mode OTR Mode Normal Mode Speed (rpm) Torque Meter Display The position of the file tip is shown by the root canal length indicator bar on the display. The apical line flashes on and off once file is inserted into the root canal.
Page 27: Operating The Micromotor
Operating the Micromotor 1. Hook the contrary electrode in the corner of the patient's mouth. Corner Corner of mouth mouth Contrary Contrary • Do not use an ultrasonic scaler with the contrary electrode electrode Electrode attached to the patient. This is dangerous because electrical noise from the scaler could interfere with canal measurements and motor operation.
Page 28 3. The file will automatically start to rotate when it is inserted into the root canal (Auto Start)*. If the root canal is extremely dry, the auto start function may not operate. • If the auto start function does not work because the root canal is too dry (infected canal etc.), moisten the canal with a liquid such as hydrogen peroxide, sodium hypochlorite or saline.
Page 29 Then hook the contrary electrode back in the corner of the patient’s mouth to start the file rotating. * Electrical noise will cause the motor to stop and automatically put ROOT ZX II into the root canal measurement mode, which is the safest mode. However, it will return to normal operation when the file is taken out of the root canal.
Page 30: Manual Mode Using The Foot Switch
• Nickel-Titanium files are more easily broken by the amount of torque applied to them than stainless steel files. Keep the following points in mind to minimize the possibility of file breakage. • Before using micromotor, use a small hand file, such as #10 or #15, to penetrate the root canal manually down to apex and then return to the apical constriction.
Page 31: Manual Mode Using The Operation Switches
Manual Mode Using the Operation Switches Forward Rotation With the file outside the canal and the motor stopped, hold down the Set switch and then press the MODE switch. (Do not reverse the switch order; this would go into the Memory function.) The file will rotate forwards at the specified speed.
Page 32: Replace Buit-In Electrode With Cap With External File Electrode
Replace Buit-in Electrode with Cap with External File Electrode If there is no electrical conductivity between the file and its shank, replace the cap with the one that has an external file electrode (sold Built-in separately). Electrode (1) Loosen the screw and take off the built-in electrode. Screw (2) Hold the push button and slide the guide bar straight in as shown in the illustration.
Page 33 (6) Hold the push button down and turn the file back and forth until is lines up with the notch and goes all the way in. Release the button to secure it. • Make sure the file goes all the way in. Give it a light tug to make sure it is held securely.
Page 34: After Using The Unit
• Use only the AC adapter made for ROOT ZX II. * The micromotor will still operate when the battery power indicator bar goes down to one line and starts flashing.
Page 35 • If [F.02] appears in the display, noise has been detected. Turn the unit off and then back on again. If [F.02] still appears, stop using the unit and contact your local dealer or J. MORITA OFFICE. 3. Amber Charge LED goes out when the battery is fully charged.
