The SCROLL Control
The SCROLL Control is a single pushbutton, to the

system status between the available modes. Pressing
the SCROLL button switches the display in the Message /
Mode LCD between:
◆

◆
AUTOWARM 4 HRS - 8 HRS
Select the OPERATE mode to make radiographs after
completing the appropriate warm-up sequence (if required).
Select the appropriate AUTOWARM mode to
“
run up
”
to the
required kV level at a fixed rate when the equipment has not
been used for a period of time (see
“
Warm Up Sequence
”
in
Chapter 5).
The X-RAY ON Control
The X-RAY ON Control, identified by the radiation
symbol, starts x-ray generation, and turns on the X-
RAY INDICATOR. The X-RAY ON Control is
active only when all of the following conditions are
met:
◆
power is applied to the system
◆
The keyswitch is turned ON
◆
all error / fault conditions have been corrected
The X-RAY Indicator
The X-RAY indicator, next to the X-RAY ON
control, is a light emitting diode (LED) that glows
red when x-rays are being generated.
The X-RAY OFF Control
The X-RAY OFF control is the red, mushroom-
type pushbutton switch, near the bottom of the
control panel. Pressing this switch anytime during
an exposure causes:
◆
termination od x-ray production
◆
the exposure counter to stop
◆
the x-ray on LED to extinguish
The timer will continue to display the exposure time or mAs
(elapsed or remaining). To continue with the exposure, re-
press the X-RAY ON button. The exposure will continue from
the point that the OFF control was originally pressed. To start
a new exposure, press the RESET button, set new exposure
factors, then re-press the X-RAY ON button.
