3.2 Operation of AeroDR Detector
3 .2 .3 Precautions for exposure
During exposure give adequate attention to the follow-
ing items.
 Exposure area
• The size lines of AeroDR Detector indicate the
exposure size.
• During exposure, place the exposure body part
within the white lines on the four corners.

 Wired connection
• When performing exposure with a wired connec-
tion, fasten the wired cable horizontally to the
wired connection connector of the AeroDR Detec-
tor. If connected at an angle, transverse (noise)
sometimes gets into acquired images after expo-
sure.
Connect it such that
there is no space.

 Wireless communications environment
• With a wireless environment, it is possible that
errors such as no wireless connection, wireless
communication terminates, and lengthened expo-
sure cycle time might occur.
HINT •••••••••••••••••••••••••••••••••• • ••
• Problems with a wireless communications environ-
ment can occur in the following conditions:
– Installed location of the access point is not good.
– When inserted in the wall stand, table, or stretcher,
the opening in the wall stand or table is too small
and there is no passage for the radio waves.
– The radio waves are not emitted due to metal parts
close to the antenna, which changes the antenna
characteristics.
– For exposures where the body touches the AeroDR
Detector directly, the radio waves are not emitted
if the body completely covers the antennas posi-
tioned in 2 places.
– Other devices use the same radio band, and cause
interference.
– When the 2.4 GHz band is used, using high
frequency therapy equipment will cause interference.
– When the DFS band is used, the access point
changes channels if weather radar or air control
radar is detected. This may cause communication
to be temporarily disconnected.

 Exposure switch
• If the exposure switch remains held down, it may
result in an afterimage becoming visible. Once
exposure is finished, release the exposure switch
immediately.
 Grid
• Use the following grid when exposing.
40 lp/cm or
Grid density
34 lp/cm
