Tilt the modem cover down.

Loosen the screw holding the modem in place with a flat screwdriver. It is a captive screw so it will not come out all the way.

Remove the modem cover by pulling forward from the left edge, and then pull it to the left to disengage it from the right hinge pin.

Snag the pull handle (wire) with a fingernail and pull the modem free of the unit.
