Use the kV and mAs fields on the Acquisition screen or the up and down arrow buttons on the control
panel (Figure 5-2) to adjust the parameters for a patient exam.
Figure 5-2 Technique adjustment buttons
1. To increase the kVp, press the UP kVp arrow. To decrease the kVp value, press the DOWN kVp arrow.
See Figure 5-2.
2. To increase the mAs, press the UP mAs arrow. Press the DOWN mAs arrow to decrease the value.
Should you reach a maximum or minimum value, kVp / mAs MAX or kVp / mAs MIN will briefly
appear on the message display to alert you.
IMPORTANT!: Carefully check the digital display (Figure 5-1) before making an exposure to ensure that
the factors selected are those that are intended. Pay particular attention to the placement
of the decimal point in the mAs setting to ensure that whole numbers are not mistaken
for an intended mAs fractional number.
