Notes
(1) All characteristics of the receiver in this specification are specified by supplying burst wave form with ROHM standard
transmitter (Shown as 8 (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.

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.
