When on, the green signal , at the top left-hand corner of the
keyboard, shows "Ready for X-rays" condition, where a touch of the
X-ray button starts exposure. This exposure enabled condition stays
until the exposure ends or for a pre-set time (variable during set-up
between 10 and 30 seconds: default 15 seconds), after which the
condition itself is disabled; in this case you must reactivate by touching
the corresponding key again.
NOTE:
When the READY key is pressed not only will exposure be enabled, but
the equipment will also start displaying exposure time on the display
calculated according to line voltage fluctuation compensation (see
paragraph 5.1).
NOTE:
If the READY key has been disabled in system configuration, the display
will show the "corrected" exposure time only during exposure or holding
the X-ray button pressed at the end of it.
NOTE:
If you touch the X-ray button when the enabling signal is not active, no
exposure occurs; at the same time the display shows the latest actual
exposure time.

The yellow luminous signal , at the top right-hand corner of the
keyboard is activated if X-rays are being emitted, signalling that
emission is actually taking place. Emission is also signalled by an
acoustic signal.

The display, in the middle top part of the keyboard has a multiple
function.
1. During the exposure preparation phase, it displays the automatically
or manually selected exposure time.
2. Soon after enabling the equipment by pressing the "Ready" key and
during the exposure phase, it displays exposure time corrected by
the equipment to compensate line voltage fluctuations, while at the
end of the exposure it displays the time that must elapse before the
end of the tubehead cooling pause.
3. At the end, if you press the X-ray button with exposure not enabled,
the display shows the latest actual exposure time.
