INTRODUCTION
The 490-95 is designed to reject interference from Plasma Displays from entering the IR signal line. These Small IR
Receivers are intended to be mounted in panels, doors, cabinets, etc. for control of A/V equipment behind closed doors or
any IR Repeater System that is in close proximity of a Plasma or LCD Displays. Modeled after the original 490-90, the
490-95 offers the same features as its predecessor but in a smaller mounting frame.
