Hand-switch positions
Position
Description
OFF
The OFF position is when no pressure is applied to the Prep/Expose button on top of
the Hand-switch.
PREPARE
PREPARE is the next position on the Hand-switch. When it is partially pressed, it
brings the rotor up to speed and heats the filament. PREPARE also checks the
system interlocks and verifies the system is ready to make an exposure. If you
release the button, it returns to OFF.
EXPOSE
The EXPOSE position is when the button on the Hand-switch is fully depressed. This
produces X-rays that are recorded. Release the Prep/Expose button after the
exposure is completed.
The system beeps as X-rays are produced. The tone ends when the exposure is
terminated or completed. The X-ray exposure indicator on the RCIM also lights up
when X-rays are produced.
