User Identification
Each group reponse keypad has a unique address between 1 and 250

via software utility. Individual pads can be password-protected to preserve configurations.
IR Technology
Proprietary two-way infrared system provides reliable line of site operation between keypads
and their associated OptionFinder IR Audience Reponse Base Station. Each keypad buffers
the response and continues to transmit until acknowledgement is received. Responses easily
bounce off walls, ceilings and other surfaces for easy point-and-click participation.
IR technology means different systems can be used in an unlimited number of rooms in the
same facility so long as the rooms do not share windows or connected visual open space. No
FCC or International licenses are required.
