SW2 - Setting for Optional 12" (30 cm) Cone
The default settings for anatomical exposure times are set at the factory for
an 8" (20 cm) focal length cone. The 12" (30 cm) cone is recommended
when using the paralleling film positioning technique. Using the longer cone
requires the use of longer exposure times. These exposure times can be
programmed into the system by changing the setting on Switch SW2.
Note! It is recommended that this procedure be performed only by a qualified
Gendex service agent.
1. Turn the system on and note the initial displayed exposure time.
Ensure that you follow the procedure referenced in the following step.
This equipment must always be electrically disconnected from the
mains electrical supply (external power source) before beginning any
procedure.
2. Follow the steps outlined in Opening the Master Control, starting on
page 1-2, to open the Master Control.
3. Locate the series of dip switches labeled SW2 located at the bottom left
of the Logic Board.
4. Set the position 3 switch to ON position.
