An exposure can be made using the handswitch that is connected to the
System Console, or by using the exposure keys on the System Console.
Make an Exposure (Handswitch)
The handswitch is a three-position push button switch. Its three positions
are OFF, Prep and Expose. The handswitch is normally in the OFF
position. See Illustration 4-4.
Press the handswitch halfway to the Prep position for 1-1.5 seconds. This
prepares the X-ray tube for exposure. Then press the handswitch all the
way down to the Exposure position and hold until the exposure is
complete. A beep will sound notifying that the exposure is complete.
X-RAY EMISSION IS TERMINATED INSTANTLY WHEN YOU
