Technique Adjustment - GE Definium AMX 700 Operator's Manual

9. Press the PREP/EXPOSE button all the way down to take an exposure. (An audible tone will sound, and
the X-RAY indicator will light up.)
If an exposure isn't taken within 10 seconds of pressing PREP, release and repeat the prep cycle.
(Release the PREP/EXPOSE button, and press to prep position again.)
If the message WAIT appears, you may still take another exposure. Although, because of
insufficient recovery time, the selected technique may be inaccurate. (Refer to
Messages on Display
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.
The kVp/mAs Numeric Display will flash for about 6 seconds after the release of the hand switch
from the PREP position, if an exposure has occurred.
10. Secure the unit for transport when the exam is complete.
11. Park tube and detector.

Technique Adjustment

The software provided with the GE Portable DR Detector contains the recommended default technique
settings for both digital and cassette exams. Technique adjustment should always be made on the
Acquisition screen. Refer to
Image Acquisition for more information.
The mAs and kVp adjustment buttons provided on the display panel should only be used if the unit
software fails. The following information is provided for reference if the software fails and techniques
must be adjusted manually.
IMPORTANT!: If the software fails, the digital detector cannot be used; exams must be taken with either
an analog or CR cassette.
When in acquisition mode, the display panel also shows the kVp and mAs values (Figure 5-1). Changing
the values on the control panel automatically updates the values on the Acquisition screen and vice
versa.
