PRECAUTIONS
• Make sure to unplug the AC power cord if something goes wrong.
• If the AC power cord is unplugged before cooling is complete, give the lamp enough time
to cool before plugging it back in. If the lamp overheats, it may fail to light. Unplugging the
AC power cord repeatedly when the temperature is high will shorten the life of the lamp.
(Even if you are not concerned about lamp lifetime, the light may not come on if you do
not wait at least 3 minutes.)
