The circuit constant is a example. It is difference from mounting equipment. Please select it by your mounting equipment.
Please be carefully not to apply exceeding the absolute maximum ratings of applying voltage and continuous high voltage spike
3. 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.
4. The shield case should be grounded on PCB pattern.
(The area across the shield case and the GND terminal is internally non-conductive.)
5. Do not apply unnecessary force to the terminal and the case.
6. Do not push the light detector surface (photodiode) from outside.
9. External Circuit Examples (Mount the outer parts as near the unit as possible).

In case the signal format of total duty and/or ON/OFF signal time dosen`t meet the conditions noted above, there is a
case that reception distance much reduces or output dose not appear.

2. Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of
light emitting device and the characteristics of the light detecting unit.
If it should be dirty, wipe off such dust and refuse with soft cloth so as to prevent scratch. In case some solvents are required, use
methyl alcohol, ethyl alcohol or isopropyl alcohol only.
Also, protect the light detecting unit against flux and others, since their deposition on the unit inside causes reduction of the
function, fading of markings such as the part number.
7. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
8. Do not use hole and groove set in the case of the light detecting unit for other purposes, since they are required to maintain the
specified performance.
