The iCue is a handheld RF (Radio Frequency) transceiver that is used by students or audience members to respond to questions posed by the instructor. They have 13 buttons for up to 10 response choices A-J or 0-9, forward and reverse keys for indexing through test questions, and a multi-function button for changing RF channels, or special status functions. When a response key is pressed, the light on the remote turns red, and when the response is successfully received by the base unit the light on the remote will turn green giving user confirmation the response was received.

Requires two AAA batteries (not included)
