Operator’s manual – Owandy-RX DC

Certain exposure values which depend on the selection of the operating parameters have been predeﬁ ned:

►

cone (8”/12”)

►

type of patient (ADULT/CHILD)

►

radiographic tecnique

►

intra-oral test

PLEASE NOTE

These values have to be considered as “recommended”: it is possible to change these values if necessary. (refer to Charter 5 and 6)

To modify these exposure values

►

radiographic voltage (60kV/70kV)

►

radiographic current (4mA/8mA)

►

type of patient (ADULT/CHILD)

►

radiographic tecnique

(refer to Chapter 4)

To modify these exposure values

►

cone (8” /12”)

►

type tubehead

►

N° of control button

change the dip-switch position, inside the timer

THIS OPERATION MUST BE CARRIED OUT BY THE INSTALLER ONLY
