■ Be careful not to let screws or other foreign matter fall into the
computer. It could cause malfunction or electric shock.
■ Additional memory module is a precision electronic component that
may be fatally damaged by static electricity. Since the human body can
carry static electricity, it is important that you discharge yourself before
touching or installing any additional memory modules. To discharge
your body’s static electricity, simply touch any metal close to you with
bare hands.
Use a point size 1 Phillips screwdriver for R850/R840 and point size 0
Phillips screwdriver for R830 to remove and fasten the screws - the use of
an incorrect screwdriver can damage the screw heads.
