Detailed below are a list of problems which may occur. Click on an error to see what action should be taken.

No camera image


To start, check the following:

  • In the Device Manager ("Start" / "Control panel" / "Hardware and Sound" / "Device Manager"), is the Omnicam listed as an image processing device? If yes, update the driver software.
  • Is the camera cable properly connected to the second cable on the CEREC AC via the circular connector (LEMO connector)?
  • Is the second CEREC AC cable properly connected to the supply board (VP) in the PC slide-in module?
  • Check the connection cable between the supply board (VP) and the mainboard (motherboard).
  • Does a CEREC 3D error message appear when the camera is supposed to be activated? If yes, load new software. If no camera image appears, replace the frame grabber card.

If you receive the message "Unknown USB device" after connecting the camera, reboot the computer

Disconnecting the camera cable from the Omnicam


The Omnicam camera cable has two parts. The first camera cable is attached to the Omnicam and with it forms a unit.

  1. Disconnect the slotted round nut with the extraction tool. Guide the extraction tool over the cable. The camera housing and the adapter ring are released. The cable grip cover is exposed.
  2. Unscrew the 2-way screwed connection of the cable grip cover with a TORX screwdriver (08x60). The stainless steel sleeve and the connector are easily accessible.
  3. Pull the connector out of the Omnicam and disconnect it. The cable is unplugged from the Omnicam.

To re-establish the connection between the Omnicam and the cable, carry out the steps listed above in reverse order. Ensure that the stainless steel sleeve and the anti-kink sleeve fit together well and that the same applies for the camera injection mould.

Error messages during camera calibration


When calibrating the Omnicam, follow the instructions in the Omnicam User Manual. Ensure that the protective cover is replaced after using the calibration set so as to prevent the camera from being contaminated. If a calibration is repeatedly unsuccessful, replace the calibration set.

Does the Omnicam require powder?

No, coating free scanning saves an additional working step, reduces the learning curve and increases patient comfort. 

Can I send digital impressions to the laboratory?

Yes, through CEREC connect. 

Where can I update my software from?

The software updates are free of charge and are available from http://www.sirona.com/en/products/digital-dentistry/restorations-with-cerec/?tab=3720. Major software updates are free to CEREC club members and will be posted out (CD format) with the licence code.

What are the dimensions of the Omnicam?

Width 350 x Height 1210 x Depth 470 (mm)

Is the Omnicam portable?

The unit is portable from one surgery to another (on one level) as it has a four castor wheels base. 



Danger of touching live parts: If the housing is damaged, there is a possibility of touching live parts inside the unit. If the housing is damaged, the unit must be put and left out of operation until it has been professionally repaired.

Regular Inspection

Some countries have legal regulations which require regular safety inspections of electrical devices or systems by the operator.

A so-called "retest" (repeat test) must be carried out for the CEREC AC acquisition unit every three years at the latest. In addition, this retest also must be performed following every repair or retrofit of components such as the PC, the PC power supply, the camera and the camera cable.

Annual maintenance performed by trained technical personnel is recommended.

Care and cleaning agents

Use only care and cleaning agents which have been approved by Sirona

Do not use the agents listed below on the LCD monitor. You can use these agents for all other surfaces, including the camera.

  • Alpro: Minuten Spray classic / Minuten Wipes / Plasti Sept / Plasti Sept Wipes
  • Dürr: FD 312
  • Kerr: CaviCide / CaviWipes

Care and cleaning of the monitor screen


The monitor screen can be wiped off with a soft cloth.

Never spray the monitor screen with a disinfectant or cleaning agent.

Surfaces (without monitor)

Use only care and cleaning agents which have been approved by Sirona


  • Do not allow liquids to penetrate into the ventilation slots.
  • Never use corrosive cleaning agents, wax or solvents.
  • Remove any dirt and disinfectant residues regularly using a mild commercial cleaning agent.
  • Do not use any coloured cloths for cleaning, since they may cause discoloration of the surfaces, e.g. in combination with disinfectants!

Protection against medicaments

Due to their high concentrations and the substances they contain, many medicaments can dissolve, etch, bleach or discolour surfaces.

The only way to prevent damage is to wipe off medicaments immediately with a damp cloth and a cleaning agent

Cleaning and setting the trackball cover ring


1. Rotate the cover ring counterclockwise and remove it.

2. Clean inner surface of cover ring (A) with ethanol (commercially available cleaning alcohol).

3. Remove the ball.

4. Wipe out the calotte (spherical cap).

5. Insert the ball.

6. Fit the cover ring and turn it clockwise until it is firmly tightened.

Setting the ease of action of the ball: For cover rings with various detent positions, the ease of action of the ball can be set by selecting the corresponding detent position.

Calibrating CEREC Omnicam

The measurement procedure used by the system requires the use of a calibrated CEREC Omnicam. The CEREC Omnicam is factory calibrated, then calibrate the CEREC Omnicam after every reinstallation and after every transport. The calibration set supplied with the CEREC Omnicam is available for the calibration process. The supplied calibration set and a USB stick form a single unit.

Recalibrate the CEREC Omnicam in the following cases:

  • Following transport (shaking stress) or during first commissioning.
  • After storage in unheated or un-air-conditioned rooms (temperature differences exceeding 30°C).
  • With temperature differences of over 15°C between the last calibration and operation.
  • In general, carrying out a calibration is the correct process in the event of errors in the acquisition process (such as poor image quality or the lack of a 3D preview). In many cases, the errors can be corrected in doing so.

Prior to the first calibration

Ensure to take note of the serial number of the calibration set when starting the calibration, which must be used at this point. The number displayed in the software and the serial number on the calibration set must be identical.

The serial number of the calibration set to be used has been set on the CEREC AC with Omnicam at the factory. Prior to the first calibration after changing the PC and when switching the calibration set, you must enter the serial number of the calibration set to be used in the software. If you do not wish to do this, you can continue with "Start calibration [54]"

When entering the serial number, the following steps should be followed:

  1. Start the CalibRegistry.exe application on the USB stick included with delivery of the calibration set.
  2. Enter the 8-digit Sirona ID. You can find the ID on the sticker on the calibration set.

         - With all future calibration work involving the "CEREC SW" software, you will be prompted to use this calibration set.

Start calibration

  1. In the software, navigate to the system menu and click on the "Configuration" button.
  2. Click on the "Devices" button.
  3. Click on the "Omnicam" button.
  4. Click on the "Calibrate" button. The camera view is displayed in one window.
  5. Follow the prompt to set up the calibration set with the corresponding ID number. At this point, check that this ID matches the ID on your calibration set. If this is not the case, go back to "Prior to the first calibration [53]"

Calibrate the camera


  • Remove the protective cap from the calibration set.
  • Mount the calibration set on the tip of the camera until it locks into place.
  • Secure the CEREC Omnicam in the calibration set using one hand. Ensure that the external calibration set screw is fully screwed in, in a clockwise motion until it gently locks into place.
  • Click the "OK" button on your CEREC AC. The measuring process starts. The software prompts you to proceed to the next latching.
  • Turn the screw counter-clockwise until you reach the next latching point.
  • Click the "OK" button on your CEREC AC. In doing so, ensure that the CEREC Omnicam does not move. The software confirms the calibration process. The software prompts you to proceed to the next latching.
  • Execute the last 2 steps a total of 11 times. The software provides status updates on the calibration and informs you once the procedure is complete. You will be prompted to measure the position of the exit window.

Measuring the position of the exit windowImage

  • Mount the bottom side of the calibration set to the tip of the camera.
  • Click the "OK" button on your CEREC AC. The calibration process is continued. Once the calibration is complete, a message is displayed indicating this.
  • Confirm the message by clicking the "OK" button on your CEREC AC. The CEREC Omnicam is calibrated.

Error message during calibration

The software indicates if an error occurs during calibration. If the calibration process resulted in errors, restart the process.

End calibration

✔ The software indicates that the calibration was completed successfully.

  • Click on the "OK" button. The CEREC Omnicam is calibrated.

Maintenance and Care

Components of the Omnicam


The CEREC Omnicam is a very sensitive optical device and must therefore be handled with the utmost care. Protect the sapphire glass and the camera window against scratching and clean them with a lint-free cloth and ethanol (commercially available cleaning alcohol).

Removing the mirror sleeve

  1. Press the mirror sleeve against the camera body.
  2. Press detent A.
  3. Pull off the mirror sleeve.

Risk of damaging the camera window or sapphire glass. Push the mirror sleeve straight toward the front; do not tilt it.



Do not spray the CEREC Omnicam or immerse it in cleaning agents or disinfectants

  • Disinfect the CEREC Omnicam (including the mirror sleeve) with a cloth which has been soaked in the agent specified in the section "Care and cleaning agents" in the Operating Instructions for the acquisition unit.


If the CEREC Omnicam accidentally falls, check to make sure that the camera window and sapphire glass are not damaged. If the CEREC Omnicam has been damaged, it must no longer be used on patients. The CEREC Omnicam must be recalibrated.

Not sterilisable: Do not under any circumstances sterilise the CEREC Omnicam or the video cable

The mirror sleeve can be sterilised with hot air (180°C, 30 min), not in the autoclave.

Refitting the mirror sleeve

Risk of damaging the camera window or sapphire glass.

  • The mirror sleeve must not come into contact with the camera window.
  • Push the mirror sleeve straight toward the camera body; do not tilt it.
  • Carefully refit the mirror sleeve until it locks in place.

Replacing the main fuse

Electric shock - Disconnect the power plug at the unit end before replacing the fuses.

Fuse type - Use only fuses of the same type in the fuse module.


The power plug must be disconnected.

  1. Unlatch the fuse module with a screwdriver and pull the module out.
  2. Replace the defective fuses.
  3. Reinsert the fuse module.

Charge battery (optional)

Reduced buffer cycles

After around 1000 buffer cycles the capacity of the battery fades due to the nature of the battery technology used.

If the buffer times are too short, you should replace the battery.

The storage battery is permanently charged during operation on line voltage. This allows brief buffer operation after 1 hour of charging.

For a complete charge, the battery must be charged without interruption for at least 12 hours. Keeping the acquisition unit connected to the mains voltage and the power switch on is sufficient here. The PC does not have to be switched on for the charging process.


  1. Open the lower door on the back panel. Use a coin to open the latch. Turn counterclockwise.
  2. Remove the battery cover.
  3. Unplug the battery connector.
  4. Unscrew the fastening screw and remove the battery.
  5. Insert the new battery into the battery compartment with the fastening screw and screw it down.
  6. Plug in the battery plug.
  7. Attach the battery cover.
  8. Put the door back in position and lock it.
