We’re experiencing our first real cold snap of the season here in the beautiful Philadelphia Metropolitan Area so it seems like a good time for a quick, weather-related warning/reminder.:

If your presentation equipment has been allowed to get very cold during transport (maybe because it’s been in your trunk instead of the nice toasty back seat for example), take it out it its case and give it plenty of time to warm up to room temperature before plugging it in and turning it on.

This is especially important for projectors. I’ve never seen it happen, but it’s not unheard of for a projector lamp to explode when going from being off and very cold to suddenly being on and very hot (betterlamp.com — see tip #4). This situation can create a nasty, expensive, dangerous mess that you do not want to experience.

And although there isn’t any danger of something exploding, you should take the same precaution with your other equipment. In the case of stuff like computers or switches, the problem will be an excess of moisture from condensation messing with the delicate electronic bits inside.

It’s probably safest to avoid letting your equipment get so cold in the first place if at all possible. In other words, take care of your projector and it will take care of you.
