CAUTION: Before performing the following procedures, read the safety instructions in your Owner's Manual.
NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist
grounding strap or by periodically touching an unpainted metal surface (such
as the back panel) on the computer.
NOTICE: Do not press down on the left side of the modem while
installing it.
Starting from the lower left corner of the modem, gently roll in the
top-left corner of the modem, placing it underneath the sponge. Gently
rolling in the modem prevents the top left corner of the modem from
contacting the system board and damaging parts.
Ensure the modem is aligned correctly, and replace the M2 x 3-mm screw.
