Device Symptom
Potential Problem
Corrective Action
6.2.1
Image from X-ray
exposure does not have
sufficient contrast.
Underexposure (too light).
Increase the exposure time setting; or see
“Incomplete Exposure” below.
Overexposure (too dark).
Decrease the exposure time setting. Also
check film expiration date (old film can
produce dark, grainy/foggy images).
Chemical developer (for
film-based imaging).
Ensure chemical freshness and proper
temperature.
6.2.2
Image from X-ray
exposure is blurred.
Combined movements
of operator and patient
during exposure produced
too much distortion.
Check the exposure time setting and re-
enable when operator and patient are again
properly situated.
6.2.3
Enabling X-rays
alert stays on.
Double triggering.
Release the trigger and wait for the
Ready
alert.
6.2.4
Device does not
shift to the
Enabling
X-rays
alert or
Ready
alert.
The trigger is pulled for
longer than one second.
Pull and release the trigger within one
second and wait for the
Ready
alert.
The device may be above
the maximum operating
temperature of 104°F
(+40°C).
Allow the device to return to the operating
range as stated in Section 8.
6.2.5 Ready
state
terminated before an
exposure started.
The
Ready
state expires
because the X-ray
exposure is not initiated
within 15 seconds of the
start of the
Ready
state.
Double-check the exposure time setting and
re-enable when operator and patient are
again properly situated.
6.2.6 Incomplete
Exposure
alarm
displayed on-screen.
Incomplete exposure:
the depressed trigger
is released before the
timed exposure is able to
complete.
This condition automatically clears within
15 seconds or by pressing any button on
the user interface panel. Be sure to depress
the trigger for the full duration of the timed
exposure.
