Chapter B - KEYBOARD FUNCTIONS & MODES
B-8 Planmeca Proline CC panoramic x-ray
Technical Manual
mA keys and display
This display indicates the selected mA - value (2 - 12 mA) of the X-ray tube.
NOTE During an exposure in the service mode this display does not indicate the selected mA-
value but the actual mA-value measured from the X-ray tube.
With the minus (-) key the mA - value can be decreased in steps of 1 mA. When kept down for
more than 0.5 seconds an auto-repeat function activates.
With the plus (+) key the mA - value can be increased in steps of 1 mA. When kept down for
more than 0.5 seconds an auto-repeat function activates.
Control (CTL) -key and indicator light
The CTL - key does not activate any operations by itself. It is used either to clear an error indica-
tion, when no further actions are taken, or to give the other keyboard keys special functions.
When the key is pressed once, the CTL indicator light comes on, indicating that the other keys
have special functions if operated. If CTL is pressed while the indicator is on, the indicator goes
off and the keyboard keys have their normal functions.
Primary slot key and display
Operating the primary slot key changes the primary slot. While the slot is changing the display of
the slot number is blinking. Operating this key changes the slots in ascending order from 0 to 3
and back to 0. In cephalostat models the slots are changed from 0 to 6 and back to 0.
NOTE In transversal slicing system models the wide slot (number 7) substitutes the reduced
height panoramic slot (number 1).
The primary slot display indicates the number of the primary slot selected. While the slot is
changing the display is blinking. In the following table it is explained, which slots correspond to
which numbers.
Slot number Slot
0 (or blank) Normal panoramic slot
1 Reduced height panoramic slot
2 Lower jaw (not in ceph. models)
3 Upper jaw (not in ceph. models)
Cephalostat models only:
4 Vertical asymmetric
5 Vertical symmetric
6 Horizontal asymmetric
Transversal slicing system models only:
7 Wide slot
