Expanding off of this . . . What does everyone do regarding "best
practice"? After reading the suggestions/tips Tim sent out
earlier . . . this one . . . I have often thought that if I could
put together a quick troubleshooting card -- or tips with the
technology (such as best practice) -- maybe I would not be drained of
energy with things I call minor repair/quick fixes.
The one that always comes to mind is quick networking/
troubleshooting: ex. I can't get mail. 1) Can you get on the
internet? Yes--probably an attachment too large . . . go online,
and give the instructions for deleting. If no, can your neighbor get
online? Yes/No. Are you set to the right location? , etc., etc.
While I believe I am the eternal optimist . . . the pessimist in me
says it's not worth the time because they'll just call or email
anyway. Then we'll all get frustrated when I say "Have you checked
your card?" Of course, people could become mini troubleshooters --
if you enforce no help until you have gone through the steps (or
things like "did you restart").
Does anybody have something like this in place? I've wondered if it
would be good to give with the gradebook instructions in the
fall . . . and any other "informative" tech. integration or the such.

As we place ore and more Projectors in classrooms and IMC's for
checkout, I was wondering if there is a "Best Practices" for there
use. I received this from another list I am on and would love
comments, recomendations, amendments and/or overa ll changes.
Thanks
LCD Projector Best Practices:
The standard rating for a projector bulb is about 2000 hrs of use.
The
replacement cost of the bulbs is about $300 each. Under normal
conditions the bulb should slowly get dimmer until by about 2000
hrs it
is dim enough to need changing. They are not supposed to actually
burn
out (but sometimes they do) The life of the bulb depends on the number
of hours it runs, but also on the way it has been warmed up and cooled
down.
Here is a summary recommendation for proper use:
1. If the projector is turned on, be sure it runs for at least 20
minutes before turning it back off. This insures it gets
completely up
to operating temperature and has been stable at that temperature for a
while before cooling down again.
2. If the projector is turned off (put into sleep mode,
never really turn it off) then do not turn it back on for 30 minutes.
The bulb has to get completely down to room temperature before
trying to
power it back on.
3. During the day if you are done but will use the
projector again in less than 20 minutes then leave it on but you can
press the "video" button to get it to the blue background. You can
then
turn it back to computer when you need it again.
4. During the day if you are done and WILL NOT be using it
for 30 to 40 minutes then please do turn it off and allow it to cool
down completely. (we have some who go to lunch and leave their
projector running)
5. Out in a corn field our power goes out. I asked about
power on/off problems with our electricity but was told as long as the
projector is asleep it should not be a problem, other than those times
when the power does the on/off/on/off flashing which is hard on
everything.
