CAUTION
• Before replacing the board or plugging/unplugging FFC, unplug Power cable and
leave it for a while. If operating with Power cable still plugged, Board may be
damaged or operators may get an electric shock by standby electricity.
• When handling board, do not touch on-board devices with bare hands.
• Before plugging FFC, check FFC terminal (to see the corner of the terminal is not
crooked and reinforcement is not peeled off).
• When plugging/unplugging FFC, do it vertically to the connector.
If plugged/unplugged obliquely, it may damage, shunt, or disconnect the
terminals inside the connector, and may damage the elements on the board.
• Make sure to plug FFC all the way. After plugging, make sure that FFC and
connector terminal are aligned and that FFC is not plugged obliquely.
