(Precautions for Use)

1) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.33µ F between V_CCand GND near the device.

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 agent.

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 contact us.

● As for other general precautions, refer to the chapter "Precautions for Use".
