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 int ernal o r extern al noise (C RT, fluorescent tub e, motor, LCD backli ght) of th e receiv er may cause ma lfunct ion
like a reduced effective distance.
(In the case of internal and external noise are strong, please use RPM7140-HxR series with holder .)
zNotes
(1) A ll characterist ics of the receiver i n this specificatio n are specified b y supplying burst wave form (Fig.1) with ROHM
standard tran smitter (Fig.2 ).
If in case of othe r burst wave form w ill be use d, please che ck these spec. C arefully und er the evaluation s.
(2) When the recei ver will be used as th e wire-less remo te controller, please use the si gnal 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)
If using other signal method, signal format, (ex: signal format which not including the leader signal) the receiver might
have chan ces to mis s-functio n.
(3) Please set up transmitter’s carrier frequency as same as the receiver’ s f0 frequency . Otherwise er ror might be
occurred.
(4) If transmission signal has non-continues carrie r , error might be occurred . Continuous carrier is nece ssary.

T2
T1≠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) Th e receiver may not work p roperly if rece iving signal judgment i s done by single pulse due to the
surrounding / environmental noises.
To prevent such misjudgme nt, please make sure that the receiver 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 su pply unnecessary stress to lead.
(1 1) 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 no t touch the lens.
(12) In order to prevent products from ESD, human body and solder iron, etc. are required to be grounded.
