■ Precautions for Use
(1) In this product, flux in the cleaning solvent may remain inside the slit of holder.
It sometimes causes lower output;therefore, cleaning is prrhibited.
(1) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.01µF
between Vcc and GND near the device.
(3) As for other general cautions< refer to the chapter “Precautions for Use”.
