Cautions regarding use in high and low temperature environments
• Whentheunitisusedinalowtemperaturespace(e.g.room,ofce),thepicturemayleavetrailsorappearslightlydelayed.
Thisisnotamalfunction,andtheunitwillrecoverwhenthetemperaturereturnstonormal.
• Donotleavetheunitinahotorcoldlocation.Also,donotleavetheunitinalocationexposedtodirectsunlightorneara
