( 1) In case of cleaning, use only the following type of cleaning solvent.
( 2) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.01
F bet-
ween Vcc and GND near the device.
Ethyl alcohol, Methyl alcohol, Isopropyl alcohol
( 3) As for other general cautions, refer to the chapter "Precautions for Use .
