s Precautions for Use
(1 ) Use the light emitting unit ( remote control transmitter ) , in consideration of performance,
characteristics and operating condition of light emitting device and the characteristics of
the light detecting unit.
( 2) Pay attention to a malfunction of the light detecting unit when the surface is stained with
dust and refuse. Care must be taken not to touch the light detector surface. If it should be
dirty, wipe off with soft cloth so as to prevent scratch. In case some solvents are required,

( 4) Do not apply unnecessary force to the terminals and case form outside.
( 5) Do not push the light detector surface ( photodiode ) from outside.
( 6) To avoid the electorstatic breakdown of IC, handle the unit under the condition of ground-
ing with human body, soldering iron, etc.
( 7) In case of adopting the infrared light detecting unit for the wireless remote control, use it
in accordance with the transmission scheme and the signal format recommended in “ Coun-
termeasures for malfunction prevention of home appliances with infrared remote control”
