(1) Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of
(2) Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse.
(3) Cleaning
(4) To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
(5) Do not apply unnecessary force to the terminal.
(6) Example of recommended external circuit (mount outer mounting parts near the sensor as much as possible.)
