Configuring Control Settings
The 765DC control panel is preset at the factory (called default settings) for
operation with a standard configuration. This configuration assumes the use of the
standard 8" focal length cone and D-speed film or a DenOptix digital imaging
system. This standard configuration presets the exposure times for the anatomical
selections. These presets can be changed for use with E-speed or F-speed film or
another type of digital imaging system, or with the optional long cone.
•The film speed and digital option can be changed using the control panel
buttons and software.
•Compensating for the cone length is done by changing a switch inside of
the control box. Note: It is recommended that this be done only by an
authorized Gendex service agent.
Changing the default settings for the film speed used
The 765DC is set at the factory for the use of D-speed film. This can be verified by
turning the control and noting that the time initially displayed is 0.320 seconds. The use of
E-speed or F-speed film requires modifying the exposure times used. The system can be
programmed to accomplish this automatically.
1. Turn the system off.
2. Press and hold the anatomical time selector switch while turning the system on (see Figure 1).
3. The time display will now read "SP 1". This confirms the system is in the film speed menu.
4. To change to E-speed. Press the exposure time 'Up' button. The time display will now read
"SP 2". This confirms that the system is now set for E-speed film.
5. Press the anatomical time selector switch again to store the new setting. The time displayed
should now indicate 0.200 seconds.
6. To change to F-speed. Press the exposure time ‘Up’ button Figure 1
again until the display reads “SP 3”.
7. Press the time selector switch to store the setting. The time

information and turn the system off. The unit should now automatically select the digital
option when first turned on.
5. To select for the unit to come on in the child mode, press the adult or child selection button
until the green light is flashing next to the child option. Press the anatomical selector switch
to store the information and turn the unit off. The unit should now automatically select the
child option when the unit is first turned on.
Modifying the system for use with the optional 12" (30 cm) cone
The 765DC is set at the factory for use with the standard supplied 8" (20 cm ) cone.
The 12" (30 cm) long cone is recommended when using the paralleling film positioning
technique along with the Rinn XCP kit. Using the long cone requires the use of longer
exposure times, which can be programmed into the system by changing an internal
electrical setting.
This modification should be performed only by a qualified Gendex service
agent. Contact your Gendex service agent to make the change.
