Using the 12 in Cone (30-A2033)
The JB-70 is set at the factory for use with the standard supplied 8 in (20 cm)
cone. The 12 in (30 cm) long cone (30-A2033) is recommended when using the
paralleling film positioning technique. Using the long cone requires the use of
longer exposure times, which can be programmed into the system by changing
an internal electrical setting. Only a qualified Progeny Dental service agent
should preform this modification. Contact your Progeny Dental service agent to
make the change.
