3 SERVICE MODE KEYBOARD FUNCTIONS

Never use special service mode functions if you are not familiar with how they operate.
The service mode is only intended for the trained technician.
CAUTION Operating the exposure switch will immediately start the X-Ray generator.
NOTE The operations of the rotation and cassette motors are disabled in this mode to allow gen-
erator operation without movements.
For further diagnosis of the equipment operation a separate service mode has been provided.
Various kinds of adjustments and calibrations can also be made in this operating mode. There
are also some special control and display modes that are not normally available but which can be
entered by certain control sequences. In this section it is explained what operations can be
achieved with the keys and which indications appear on the displays.
