INCREASE / DECREASE: Radiographic technique values are increased or
decreased by pressing the respective push-buttons. The values increase or
decrease step-by-step each time the corresponding push-button is pressed,
and changes faster when either of them is pressed continuously.
kV: Selects the X-ray Tube voltage.

mAs: Selects the exposure in mAs.

mA: Selects the X-ray Tube current.

s: Selects the exposure time in seconds.

(Refer to Section 9.3 for Factor ranges)
If after pressing any of these push-buttons, the technique value is
blocked and an acoustic signal is emitted it could mean that:
Radiographic Parameters Blockage. When any of the
maximum or minimum radiographic parameter limit is reached, its
related Display blinks.
Generator Power Limit. If the power limit (kV x mA) is reached
by increasing the mA up to a maximum possible value, the mA
value is blocked. Flashing values on kV and mA Displays will alert
operator about the situation.
If required, kV could be increased up to its maximum value while
mA value may automatically decrease, as long as mAs value is
kept the same.
Space Charge. If a variation of the kV or mA induces to reach
space charge limit in the selected tube, the parameter is blocked,
and flashing value on the kV Display will alert operator about the
situation.
Maximum Energy (60 kJ). Only in AEC mode, if a variation of the
parameters means that the maximum energy (60 kJ) will be
exceed, the parameter is blocked. Flashing values on kV and mAs
Displays will alert operator about the situation.
Instantaneous Power. If a technique reaches the instantaneous
power limit of the X-ray Tube (ratings limit or the X-ray Tube is
momentarily overheated), some techniques cannot be selected.
Flashing values on kV and mAs Displays will alert operator about
the situation.
