Be sure to disconnect the power cable from the AC outlet
whenever removing the card flexible cable from the
connector for maintenance, etc. Hold the both sides of the
card flexible cable with both hands to disconnect the
cable straight. (Even if the power has been switched OFF,
previously charged voltage may remain in the capacitor,
etc. If the electrodes of the card flexible cable and those
of the connector come in contact by accident, a malfunction
may occur.)
