zHow to use the receiver without holder
Please use the receiver with shield case or shield plate as an EMI noise measures.
(Shield case and shield plate are required to be grounded.)
Because internal or external noise (CRT, fluorescent tube, motor, LCD backlight) of the receiver may cause malfunction
like a reduced effective distance.
(In the case of internal and external noise are strong, please use RPM7136-HxR series with holder.)
zNotes
(1) All characteristics of the receiver in this specification are specified by supplying burst wave form (Fig.1) with ROHM
standard transmitter (Fig.2 ).
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 method the signal method the
signal format which refer to “Measures to prevent malfunctioning of IR remote-controlled electric home appliances”.
(Published July 1987 by Association of Electric Home Appliances) Other examples for suitable signal format are RC5
Code, RC6 Code, RCMM Code. If using other signal method, signal format, (ex: signal format which not including the
leader signal) the receiver might have chances to miss-function.
(3) Please set up transmitter’s carrier frequency as same as the receiver’s f
0 frequency. Otherwise error might be
occurred.
(4) If transmission signal has non-continues carrier, error might be occurred. Continuous carrier is necessary.

(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 receiving signal judgement is done by single pulse due to the
surrounding / environmental noises.
To prevent such misjudgement, please make sure that the receiver is set up to work only when receiving
series of coded signal.
(8) Emitting unit (remote control transmitter) has to be considered about its emitting device function, characteristics and
characteristics of the receiver.
(9) Please connect ‘Holder’ on to the ‘Ground (GND)’ of PCB. If the holder is not connected to the GND, there is a
possibility of worsening the characteristics of product.
(10) Do not supply unnecessary stress to lead.
(11) Please pay careful attention to the lens.
It might have a chance to miss-function when the lens get dust or dirty. And also please do not touch the lens.
(12) In order to prevent products from ESD, human body and solder iron, etc. are required to be grounded.
