Cordless headset using IR signals

摘要

A cordless headset, 100, communicates with a handset, 200, through infra red signals and with the base unit, 300, via a wireless link. The infra red receiver may be mounted facing towards the front of the headset. The handheld controller may contain a keypad and a coding circuit connected to the keypad for driving an infra red LED positioned facing the topside of the controller. The commands corresponding to the infra red signal may be performed by the headset or the base unit.
