Wifi Audible Warnings – X-Ray Emissions
The MINI Z has one audible X-ray generation indicator. It consists of an audible beep.
The quantity of beeps can be configured on the tablet to match local governmental regulations:
•
Normal
– At the beginning of an X-ray emission, one beep. At the end of an X-ray emission, two
beeps. There are no beeps during the X-ray emission.
•
Extended
– At the beginning of an X-ray emission, five beeps. At the end of an X-ray emission,
two beeps. During the X-ray emission, one beep every second of time.

Interlocks – X-Ray Emissions
The MINI Z scanner has several mechanical interlocks:
•
A key on the scanner housing for main scanner power on/off (see
Figure 2-6
)
•
Two trigger buttons on the scanner handle, wired in parallel; at least one button must always be
pressed down in order for X-rays to be emitted (see
Figure 2-6
)
•
In the interior of the scanner, Mechanical Interlock 1 ensures that all primary X-ray shielding is in
place before X-ray emissions are enabled.
Figure 2-5: Dual laser beams visually indicate the X-ray beam path. The
upper left panel shows the left-right beam fan angle of approximately 60°. The
up-down fan angle is negligible, as indicated by the blue arrows in the upper
middle panel.
