How Do I Mount the DPH650 on the Wall?
5 Are you mounting the DPH650 into a drywall or concrete surface where a
wooden stud is not available?
If yes, drive the anchor bolts into the wall and then go to step 6.
If no, go to step 6.
6 Install the mounting screws into the wall or the anchor bolts, as appropriate, and
leave a gap of about 1/4-in. between the screw head and the wall.
7 Verify that no cables or wires are connected to the DPH650.
8 Lift the DPH650 into position. Slip the large end of both mounting slots (located
on the back of the DPH650) over the mounting screws, and then slide the modem
down until the narrow end of the keyhole slot contacts the shaft of the screw.
Important: Verify that the mounting screws securely support the DPH650 before
you release the unit.
9 Connect the cables and wires to the DPH650.
