CAUTION
When Inserting an MCU into the Adapter:
• Be careful when attaching to the PROM programmer because incorrect insertion can
cause fatal damage to the MCU.
• When opening and closing the IC socket, keep the IC socket side above and
horizontal. Otherwise the inside of the IC socket may become damaged and cause
an electrical insulation failure.
