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.

• 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.
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/
