Warm-Up Cycle
When you first power on the unit, the x-ray tube may or may not need to be
properly warmed up (a warm-up is required every 40 hours or if there has been an
electrical disruption). If the x-ray tube needs to be warmed up the system status
box will say
WARMUP REQUIRED
.
It is important to perform the warmup if this
message appears.
If the tube doesn’t need to be warmed up, the status box will say
X-RAY OFF.
