Taking Exposures

Steps
Note:
Check the battery status and message displays for battery condition. It's important to
note that you do not have to raise your kVp or mAs value to compensate for low battery
voltage.
Once you've positioned patient and cassette, selected technique and the proper safety
precautions are taken, follow these steps.
1. Remove handswitch from saddle. Press the handswitch button half way to the
PREP position. Accelerating the rotor to proper speed takes about 2.5 seconds.
D
READY FOR X−RAY will appear on the message display.
You may, if you wish, press the button all the way down to take an exposure.
The 2.5 second prep cycle is automatic. (If PREP/EXPOSE positions are
pressed simultaneously, READY FOR X−RAY will not display.)
2. Press the PREP/EXPOSE button all the way down to take an exposure. (An audi-
ble tone will sound, and the X−RAY indicator will light up.)
D
If an exposure isn't taken within 30 seconds of pressing PREP, release and
repeat the prep cycle. (Release the PREP/EXPOSE button, and press to
prep position again.)
D
If the message WAIT appears, you may still take another exposure. Although,
because of insufficient recovery time, the selected technique may be inaccu-
rate. (Refer to Messages On Display in this manual for a complete description
of all x−ray messages.)
D
HEAT WAIT displays when the tube anode is cooling. No exposures can be
taken while this message appears. (The length of the delay will vary with the
selected technique.) If an exposure is attempted while HEAT WAIT is active
X−RAY DISABLED will be displayed.
D
The kVp/mAs Numeric Display will flash for about 6 seconds after the re-
lease of the handswitch from the PREP position, if an exposure has oc-
curred.
3. Secure the unit for transport when the exam is complete.
