1.4 Caution
• Do not apply force to the top cover (See figure below).
• Do not cover the breathing hole on the top cover (See figure below).
• Do not touch the interface connector pins or the surface of the printed circuit board
• This drive can be damaged by electrostatic discharge (ESD). Any damages incurred to the drive after its
removal from the shipping package and the ESD protective bag are the responsibility of the user.
