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. Unnecessary force shoud not be applied to terminal.
5. Do not push the light detector surface (photodiode) from outside.

・ON signal time TON：200μs or more.
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.
6. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
7. Since conductive thermo plasticity is used in 2nd mold regin,please be careful not to come in contact with PCB land
