Operating Procedure - GENDEX 765DC Manuel De L'opérateur

OPERATING PROCEDURES
1. Switch the power switch to the "On" position. The Ready indicator lamp on the front
of the control panel will light.
2. Select or verify that the unit is set for either film or digital imaging. The indicator
light should be lit next to the appropriate graphic icon. Press the button between the
two icons to toggle to the correct selection.
3. Select or verify that the system is set for the appropriate patient selection (i.e. an adult
or child). Press the button between the two icons to toggle to the correct selection.
4. Press the selector button in the center of the control to toggle the indicator lamp until
it lights next to the tooth (or bitewing) symbol for the area that you wish to x-ray.
Note: The exposure time defaults (the times displayed when the system is initially
turned on) can be modified per the instructions in the Configuring Control Settings
section on page 10.
5. If desired, the up or down buttons can be used to select a specific exposure time other
than the default setting using the R10 scale. For recommendations for Occlusal film,
see the Default and Recommended Exposure Tables on page 12.
6. Position the tubehead to the patient using standard accepted positioning procedures.
Note: Care should be taken to not place fingers in areas where they may be
potentially pinched during the movement of the arm. Also, be careful to not have the
tubehead hit the wall after returning the arm to the storage position.
7. Prior to making the exposure, verify or modify the time settings as necessary using
the secondary tubehead controls. Note: The unit is supplied with an 8" (20cm) cone.
An optional longer 12" (30cm) cone can be used to sharpen the image as when the
paralleling technique is used. A rectangular cone is available as an option to reduce
the x-ray field size to that of the film and reduce the radiation to the patient.
8. When using the optional coil-cord exposure switch, it is strongly recommended that
the operator exit the operatory. Note: In order to comply with regulations and good
safety practices, the technique factors must be visible to the operator from the remote
location.
9. Press and hold either the coil-cord or push-button exposure switch until the audible
signal and exposure indicator light terminate. (Note: Releasing the exposure button
at any time will immediately terminate the exposure).
