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.
To initiate a warm-up;
1. Press WarmUp on the main menu
2. The WARM-UPCYCLE menu will appear (see
figure at the right).
3. There are two pre-programmed warm-up
cycles labeled: NORMAL and EXTENDED.
Unless you know that the unit hasn't been
used for a couple of months, select
NORMALNORMAL
4. Press START (at the bottom of the screen).
5. The message in the white system status box
will indicate WARMUP IN PROGRESS. The
flashing indicator lights on the unit will flash
on and off indicating that x-rays are being
produced. Leave the room for 15 minutes and
note on the sign up sheet that a warm up was
needed.
6. After the warm up is completed (theNORMAL
warm-up cycle takes approximately 10
minutes), that system status block will
indicate WARMUP COMPLETE. Press MAIN to
take you back to the main menu. You are now
ready to perform an irradiation which is
discussed in the next section.
