1 WARNINGS
WARNING
THE FOLLOWING WARNINGS, CAUTIONS AND NOTES MUST ALWAYS BE CONSIDERED
WHILE SERVICING, IN ORDER TO AVOID EITHER PERSONAL INJURY OR DAMAGE TO
THE UNIT.
CAUTION RADIATION SAFETY RULES
Some procedures described in this manual produces X-ray radiation. Always follow rules
for radiation safety.
Never touch or scratch the surface of the x-ray tube radiation window. The window is
made of beryllium that can be harmful if inhaled or swallowed.
Never attempt to open the TUBE-HEAD. It does not contain any serviceable parts and this
would make it inoperable and void the warranty.
Never make any exposures without the Mo/Al filter in the beam, or without the beam limit-
ing device (collimator) in place. Otherwise the radiation safety cannot be guaranteed.
CAUTION ELECTRICAL SAFETY RULES
The unit contains hazardous voltages. While servicing internal parts, always disconnect
the unit from the mains (if possible) by removing the plug from the wall outlet, and wait for
2 minutes before touching any electrical parts.
Always replace the fuses with ones of the same type and rating. Otherwise patient, opera-
tor or equipment safety cannot be guaranteed.
The circuit boards can be damaged due to static discharges and requires careful handling
and storage.
CAUTION GENERAL SAFETY RULES
The unit must be serviced only by qualified personnel, trained by PLANMED 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 jeopardize the function of the unit, if not fol-
lowed as stated.

MANUAL VERSIONS
Technical Manual
2 MANUAL VERSIONS
PLANMED pursues a policy of continuous product development. Although every effort is made to
produce up-to-date product documentation this manual should not be regarded as an infallible
guide to current production specifications. Planmed reserves the right to make changes to speci-
fications without prior notice. This manual is valid for all versions of the Sophie Mammogra-
phy X-ray units with SID 650mm. In case you have the unit with SID 600mm, you need a
technical manual revision 9.
3UNITMODELS
All Sophie Mammography X-ray unit models are electrically and mechanically identical, except
for some minor details. This manual is valid for all versions since the differences are small.
The darkroom versus daylight differs only in the size and dimensions of the cassette table and
film marking device.
The mobile versus the stationary units differs only in the base wheel system and the X-ray tube
locking system (for transportation).
Daylight units can be converted to darkroom units (and vice versa), please contact PLANMED for
details.
NOTE THIS TECHNICAL MANUAL IS VALID FOR SOFTWARE REVISIONS: TUBE CPU 2.41
(OR LATER) AND REAR CPU 4.41 (OR LATER).
If you find that your SOPHIE doesn’t have some keyboard functions, or its keyboard
functions differs from procedures described in this manual, then either the software
must be replaced with at least the above mentioned revision, or you have to relate to
an older version of this manual. The former procedure is recommended.

SOFTWARE REVISIONS & COMPATIBILITY
Technical Manual
4 SOFTWARE REVISIONS & COMPATIBILITY
Background
Since this unit is fully microprocessor controlled, its operation is controlled by the currently
installed software. PLANMED reserves the right to improve functionality or to add new features to
the product by modifying the software and/or hardware. Manuals are updated accordingly and
technical bulletins published in order to inform about these changes or additions.
Hardware compatibility
As a general rule; new software releases are compatible with all existing hardware. New software
releases (or possible upgrading kits containing new software) are normally directly compatible
with existing hardware, but not necessarily without some re-calibration procedures.
Software numbering & compatibility
Since the unit contains two communicating microprocessors, these must be able to “understand”
each other.
Incompatible software versions should never be used together, the unit would either be totally
non-functional, produce continuous error codes, or some important features or functions could be
missing. However, no damage or safety hazard would result if two non-compatible software chips
are accidentally used together.
The following table contains information about compatible software versions. Use versions
together only as listed in this table.
