5. ies Application Advisory AA 03 is a complete IR Trouble Shooting Guide For non operation or intermittent control try the following 1 The most common indication of IR interference is if the 291 95 s TB LED is ON constantly or flickers often This can be caused by numerous sources of Interference a RF Interference Depending upon the surrounding environment and Wire Run Lengths RF interference can cause the Talk Back LED to Flicker often or cause the LED to be on Constantly Examples sources of RF Interference can be from TV Transformers Dimmer Circuits Large Power Supplies High Current Electrical Lines and PC Equipment e Isolate the source of the interference by turning off suspected sources and seeing if proper IR control can be achieved Try relocating the 291 95 to minimize effects from the interfering RF source e If the RF source is coupling into the wire itself try re routing the wire isolating it from the interfering source or try the following 1 Increase the wire gauge for the IR Receiver 2 Use a shield as a DRAIN connecting it to GND on the Connecting Block side ONLY Note Do not connect the Shield at both ends as this can cause Capacitive interference 3 If using CAT5 Wire you must utilize all 8 conductors of the wire Use all 4 White Stripe wires for the GND connection 2 Solid Wires for 12VDC and the last 2 Solid Wires for IR Signal This will ensure that all lines are properly coupled to GND to minimize RF interfe
