■ Precautions for Use
( 1 ) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.33µ F
between Vcc and GND nea
( 2 ) Please do not perform dip cleaning or ultrasonic cleaning because lens part of this
product is an optical device of acrylic resin.
( 3 ) Remove dust or stains, using an air blower or a soft cloth moistened in cleaning solvent.
However, do not perform the above cleaning using a soft cloth with cleaning solvent in the
marking portion.
In this case, use only the following type of cleaning solvent used for wiping off :
Ethyl alcohol, Methyl alcohol, Isopropyl alcohol
When the cleaning solvents except for specified materials are used, please consult us.
( 4 ) As for other general cautions, refer to the chapter “Precautions for Use ” .
