#64AEC/E The density display shows E. The mAs display shows
thickness and kV display shows the initial kV for this
thickness. In this mode, the initial kV for different thicknesses
can be programmed (only used by Alpha RT AA-mode). This
setup has to be done both for the molybdenum and the
rhodium filter, and also separately for the bucky, cassette
tunnel and magnification table.
To change kV table:
Use the initial kV table (see next page) to design new values.
1 Select molybdenum filter.
2 Install cassette holder (bucky, cassette tunnel or mag.

3 Drive the compression to 0 cm (Driving the paddle up
and down you cansee initial kV values for different
thicknesses).
4 Select the initial kV value for 0 cm with Density +/-
buttons.
5 Drive the compression paddle up 0.5 cm and select the
initial kV value with Density +/- buttons.
6 Repeat point 5. until you have programmed the initial
kV for 9.5 cm.
7 Install next cassette holder and repeat the kV
programming.
8 Select rhodium filter and repeat the same kV
programming for all cassette holders.
Pressing mAs- button resets the kV tables to factory default
values.
