s 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 ”.
