CAUTION

Caution to Be Taken for SOP Version IC Socket:

• SOP version IC sockets (mounted on the PCA4738F-42A) have a sliding bar in the

middle of the board. Be sure to keep the bar to the side of the diagonally shaded area
imprinted on the board (factory-setting). An improper setting will cause fatal
damage to the MCU due to faulty connections.

Caution to Be Taken for Opening and Closing the IC Socket:

• When opening and closing the IC socket, hold the adapter horizontally as shown in

Figure 3.7. Otherwise the inside of the IC socket may become damaged and cause
an electrical insulation failure.

Caution to Be Taken for Handling an MCU:

• Do not directly touch the connector in the IC socket and the pins on the PROM

programmer connector because dirt may cause an electrical insulation failure. When
not using this product, attach the connector pins of this product to the conductive
sponge as it was shipped from the factory.
