1 General and technical data
1.1 Introduction
The Planmeca Viso X-ray unit uses Cone Beam Computed Tomography
(CBCT) to produce three-dimensional (3D) X-ray images. Panoramic,
cephalometric and projection radiography techniques can be used for two-
dimensional (2D) X-rays.
This manual describes how to maintain and service the Planmeca Viso X-ray
unit. These instructions include options that may not be available in all
countries.
1.1.1 Manual versions
Planmeca pursues a policy of continual product development. Although
every effort is made to produce up-to-date product documentation this
publication should not be regarded as an infallible guide to current
specifications. We reserve the right to make changes without prior notice.

1.2 Warnings and cautions
WARNING
THE FOLLOWING WARNINGS, CAUTIONS AND NOTES MUST ALWAYS
BE CONSIDERED WHILE SERVICING THE UNIT, IN ORDER TO AVOID
EITHER PERSONAL INJURY OR DAMAGE TO THE UNIT.
WARNING
In the ME containing batteries shall include warning notice and marking as
specified etc. housing, connection (Polarity) , type, overcharging, marking
(lithium) and current/voltage protection.
WARNING
Avoid the risk of electric shock by only connecting this equipment to a supply
mains with protective earth.
WARNING
ELECTRICAL SAFETY RULES
The unit contains hazardous voltages. While servicing internal parts, the
power supply must be disconnected externally from, for example, a fuse or a
mains switch. The fuse or main switch must be lockable into off-position.
Turning off the unit from its own mains switch DOES NOT cut off the mains
voltage from all internal nodes.
Wait for 2 minutes before touching any electrical parts.
WARNING
Do not modify the X-ray unit. The X-ray unit must be serviced by qualified
personnel only, with authorisation from the manufacturer.
WARNING
RADIATION SAFETY RULES
Some procedures described in this manual produce X-ray radiation. Always
follow the rules for radiation protection.
Never attempt to open the tube head. It does not contain any serviceable
parts, and radiation safety can no longer be guaranteed.
Never make any exposures without the filter or the beam limiting device
(collimator) in place. Otherwise the radiation safety cannot be guaranteed.
WARNING
ELECTRICAL SAFETY RULES
The unit contains hazardous voltages. While servicing internal parts, the
power supply must be disconnected externally from, for example, a fuse or a
mains switch. The fuse or main switch must be lockable into off-position.

CAUTION
Use protective eye-wear when changing the battery.
CAUTION
The maximum temperature of the tube head is limited to 60° C (140° F). The
rubber bellows inside the tube head keep the pressure constant within the
allowed temperature range.
CAUTION
EMC requirements have to be considered, and the equipment must be
installed and put into service according to the specific EMC information
provided in section "EMC information" on page 27.
CAUTION
Portable and mobile RF communications equipment can affect the X-ray
unit. For minimum distance between portable and mobile RF
communications equipment and the X-ray unit, see section "EMC
information" on page 27.
CAUTION
ELECTRICAL SAFETY RULES
Always replace the fuses with ones of the same type and rating. Otherwise
patient, operator or equipment safety cannot be guaranteed.
The circuit boards can be damaged due to static discharges and requires
careful handling.
CAUTION
GENERAL SAFETY RULES
The unit must be serviced only by qualified personnel, trained by
PLANMECA. Repairs and parts replaced by unqualified personnel carry no
warranty.
Periodical maintenance as described in this manual must be performed on a
regular basis, to ensure the safety and image quality of the unit.
Some procedures described in the unit could be dangerous, if not followed
as stated.
NOTE
The display values shown in this manual are only examples and should not
be interpreted as recommended values unless otherwise stated.

When you switch the X-ray unit on the main display will be shown on the
control panel and the X-ray unit will carry out a self-test which takes
approximately 75 seconds.
The X-ray unit is then ready for use.
NOTE
To prolong the lifetime of the Planmeca Viso X-ray unit, always switch off the
X-ray unit when it is not in active use.

If you want to pause a function (instead of cancelling it) touch the pause
button.
To scroll a list down or up, slide your finger on the screen.
To change a setting, select the service spanner at the top left corner of the
main view. This will take you to the settings menu where you can adjust the
settings of the X-ray unit.
1.4.2.1 Calibrating touch screen display
In case the touch screen is not working accurately, e.g. touching button on
the screen activates task of the button next to it, or it is just hard to activate
desired button or area on the screen, calibrate the display.
Normally, there is no need to calibrate the display at all, but the factory made
calibration remains valid.
To calibrate the display, follow the steps below.
1. Switch on the X-ray unit.
2. As soon as the screen displays text Touch the screen now to start
calibration, touch the screen. The calibration screen appears.
3. In the calibration screen, five calibration adjustment markers will appear
on the display, one at a time:
• 1st in the left up corner
• 2nd in the right up corner
• 3rd in the right bottom corner
• 4th in the left bottom corner
• 5th in the center of the display.
4. Touch the adjustment markers in the order they appear on the screen.
After touching the final adjustment marker, the X-ray unit will start up
normally.
1.4.3 Emergency button
The emergency stop button is located on the top of the stationary column.

Technical manual Planmeca Viso 7

Press the emergency button to stop the X-ray unit operating in an
emergency. When the emergency stop button is pressed down, all
movements of the X-ray unit are blocked and the unit will not generate
radiation. The up / down movement will stop within a distance of 10 mm (0.4
in.).
A help message will appear on the touch screen. Guide the patient away
from the X-ray unit. Then release the emergency stop button. The X-ray unit
will automatically restart.
