• The conditions of the S value corresponding to
the maximum exposure time and the DR Detec-
tors corresponding to them are as follows.

• To use a grid in Aero Sync mode, align the orien-
tation of the triangular mark of the DR Detector
with the grid bar as shown in the following gure.

• If the DR Detector is used in an orientation where
the grid bars are turned 90 degrees with respect
to the triangle mark on the DR Detector, observe
the following conditions:

• Do not use additional lters for exposure dose re-
duction.
• When another system performs X-ray exposure
in the exposure room where the DR Detec-
tor is placed, the DR Detector may incorrectly
sense the X-ray exposure and transfer images.
Do not use the image processing controller to
make the DR Detector ready for exposure.
Aero Sync mode exposure when radioac-
tive substances remain
• If there are any radioactive substances remaining
in the patient's body after nuclear medicine test-
ing or some other reason, the AeroDR 2 1417HQ,
AeroDR 2 1417S, AeroDR 3 1417HD, AeroDR 3
1717HD and AeroDR 3 1012HQ may recognize
that X-rays were emitted and start image transfer.
When the image is transferred, change the X-ray
sensitive setting of the image processing control-
ler to "Large" before performing exposure.
• If you change the X-ray sensitivity to "Large" in
AeroDR 2 1417HQ and AeroDR 2 1417S, make
sure that all of the following conditions are met
before performing exposure. If you perform expo-
sure under other conditions, you may not be able
to get an image.
– On the DR Detector, set up an area (2 cm x 2
cm or larger) on which the X-rays are emitted
directly.
– Emit the X-rays onto the entire DR Detector.
– Emit the X-rays by using a tube current of 140
mA or higher or a tube voltage of 90 kV or
higher.
• If you change the X-ray sensitivity to "Large" or
"Med" in AeroDR 3 1417HD, AeroDR 3 1717HD
and AeroDR 3 1012HQ, make sure that all of the
following conditions are met before performing
exposure. If you perform exposure under other
conditions, you may not be able to get an image.
– Emit the X-rays onto the entire DR Detector.
– Emit the X-rays by using a tube current of 140
mA or higher or a tube voltage of 90 kV or
higher.
S-SRM connection
• When S-SRM connection is adopted, make sure
to perform exposure using the hand switch con-
nected to the AeroDR Interface Unit2, AeroDR
Generator Interface Unit and AeroDR Generator
Interface Unit2.
• If exposure is performed using the hand switch on
the operation panel of the X-ray device, exposure
synchronized to the this device is not possible.
