[Caution in the gallium arsenide (GaAs) product handling]
This product uses gallium arsenide (GaAs) of the toxic substance appointed in laws and ordinances.
GaAs vapor and powder are hazardous to human health if inhaled or ingested.
・ Do not dispose in fire or break up this product.
・ Do not chemically make gas or powder with this product.
・ When discard this product, please obey the law of your country.
・ Do not lick the product or in any way allow it to enter the mouth.
[CAUTION]
Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times from ESD. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without
detection. Industry-standard ESD precautions should be used at all times.
