*NOTES
ON HANDLING
1.Cautions regarding noise
Be aware that power is suddenly into the componment any surge current may cause damage happen,
even if the voltage is within the absolute maximum ratings.
CAUTION
Within this device there exists GaAs (Gallium Arsenide) material which is a harmful substance if ingested.
GaAs dust and fumes are toxic. Do not break, cut or pulverize the product, or use chemicals to dissolve them.
