■ Precautions for Use
(1)
In case of cleaning, use only the following type of cleaning solvent.
Ethyl alcohol, Methyl alcohol, Isopropyl alcohol
(2)
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 .”
