Q: Is there an auto shut-off feature?
A: Yes, actually i>clicker offers two battery-saving features. As long as a remote is actively communicating with a receiver (i.e. a student uses it to vote), that remote will remain on for 90 minutes after the last vote. If a remote is accidentally turned on or buttons compressed but that remote is not communicating with a receiver (i.e. in a backpack or purse), the remote will automatically turn off after 5 minutes.
