zNotes
(1) All characteristics of th e receiver in this s pecification are s pecified by sup plying burst wave form (Fig. 1) with ROHM
standard transmitter (Fig.2 ).
If in case of other burst wave form w ill be used, p lease check th ese spec. Ca refully under the evaluations.
(2) When the receiver will be used as the w ire-less remote contro ller , please use the signal method the signal fo rmat
which refer to “Measures to prevent mulfunctioning of IR remote-controlled electric home appliances”. (Published July
1987 by Association of Electric Home Appliances)
If using other signal method, signal format, (ex: signal format which not including the leader signal) the receiver might
have chances to miss-functio n.
(3) Please set up transmitter’s carrier frequency as same as the receiver’s f
occurred.
(4) If transmission signal has non-continues carrie r , error might be occurred . Continuous carrier is nece ssary.
0 frequency. Otherwise error might be
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 w ork properly if re ceiving signal judgem ent is done by single pulse due to the
surrounding / environmental noises.
To preven t such misjudgement, please ma ke sure that the rece iver is set up to w ork 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 and holder.
(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.
