s Precautions for Use

( 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.

( 2) In case of cleaning, use only the following type of cleaning solvent.

Ethyl alcohol, Methyl alcohol, Isopropyl alcohol

( 3) As for other general cautions refer to the chapter “ Precautions for Use ” .
