Press the MODE button from the Home Screen
to display the Mode selection list. A screen similar
to the one shown on the left side appears on the
display.
Use the UP/DOWN keys to navigate within the
list. Press these buttons until the desired mode is
highlighted.
Press the SET key to use the highlighted mode.
The screen returns to home screen with the newly
selected mode abbreviated on the top right side of
the display.
NOTE
History mode loads the last used exposure parameters for current
session. Hence the option will not be available before the first exposure.
On choosing this option a list containing previous (40) exposures are
displayed. Scroll through the list using the arrow keys and press SET key
to use the highlighted item.
5.2. Selecting a Pre-set
A pre-set is a combination of patient type and tooth anatomy which the console
uses as an index to retrieve a pre-programmed set of kV, mA and ms. For each
mode (except History mode) there are 30 pre-sets available. To select one from
this 30, use the patient type key and the tooth anatomy keys.
E.g. to take X-Ray image of maxillary canine of a child
• Repeatedly press the ADULT/CHILD key to select child (bottom LED).
• Repeatedly press the BITEWING/ENDONOTIC key until both its LEDs
are off.
• Repeatedly press the CANINE key until the maxillary (top) LED is turned on.
NOTE
MOLAR, CANINE or INCISOR anatomies are selectable only if the
BITEWING/ENDODONTIC selection is set to either endodontic
or none. Similarly OCCLUSAL is selectable only if BITEWING/
ENDODONTIC is set to none.
