Setting Default Startup Parameters
Default startup techniques may be programmed by the operator in the following
manner:
1. Depress and hold the button at the lower left corner of the display screen while
turning the generator ON. The default startup screen will appear as the
generator is in its power up sequence.
2. You may now select the default settings for the following parameters:
• Startup mode (2 or 3 point mode, APR, optional AEC)
• Default 2 point kV
• Default 2 point mAs
• Default 3 point kV
• Default 3 point mA
• Default 3 point Time
• Default focal spot
• Default image receptor (Wall, Table, or None)
• Default screen contrast
3. To exit this screen and save your changes, press <exit>. The generator will
now complete its power up sequence and default to your new settings.
Prep and Expose
To make an exposure:
1. Press and hold down the PREP button
When the green READY light turns on above the PREP button, continue
holding down the PREP button while you press the EXPOSE button.
When the exposure occurs, the red X-RAY light above the EXPOSE
button will be illuminated and an audible tone will sound for the duration of
the exposure.
Continue to hold down both buttons until the red x-ray light goes out and the
audible tone ends. Releasing either of the two buttons during an exposure
will cause the exposure to terminate and a BUTTON FAULT error
message to be displayed.
Using the Rotational Knob
The rotational knob used in conjunction with the kV, mAs, Time, and centimeter
thickness buttons. When one of those buttons is pressed, that parameter is
highlighted on the screen in reverse video. The values are changed with the
increment or decrement buttons.
