If in case of other burst wave form will be used, please check these spec. carefully under the evaluations. (2) When the receiver will be used as the wire-less remote controller, please use the signal format RC5 Code, RC6 Code, RCMM Code. If using other signal method, signal format, the receiver might have chances to miss-function. (3) Please set up transmitter’s carrier frequency as same as the receiver’s f0 frequency. Otherwise error might be occurred. Rev.A 4/6 RPM7236-Hx series Photo Link Module (4) If transmission signal has non-continues carrier, error might be occurred. Continuous carrier is necessary. T1 T1≠T2 T2 (5) The receiver was designed to use as in-door use only. Therefore, please understand that the receiver cannot cover all characteristics, in case of using it out-door. (6) Noise environment (Light noise from inverter Lamp, and other kind of Lamps, Power ripple, electromagnetic noise from power circuit, and etc) may cause a reduced effective distance. (7) The receiver may not work properly if the receiving signal judgment is done by single pulse due to the surrounding / environmental noises. To prevent such misjudgment, please make sure that the receiver is set up to work only when receiving series of the coded signal. (8) Emitting unit (remote control transmitter) has to be considered about its emitting device function, characteristics and characteristics of the receiver. (9) Attach holder on PCB pattern. (Holder do not conduct to GND) (10) Do not supply unnecessary stress to lead and holder. (11) Please pay attention to the lens carefully. It might have a chance to miss-function when the lens get dust or dirty. Also, please do not touch the lens. (12) In order to protect the products from ESD, human body, solder iron and etc. are required to be grounded.
