Wall Mounting
Number of screws: 2 pieces.
Direction for wall mounting: LED panel upward.
Dimension for the screw: 4.4 mm.
There are 4 slots on the underside of the gateway that can be used for wall mounting.
Note: When wall mounting the unit, ensure that it is within reach of the power outlet.
You will need 2 suitable screws which screw diameter would be 4.4 mm to wall mount the Cable
Modem..
To do this:
1.
Ensure that the wall you use is smooth, flat, dry and sturdy and use the 4 screw holes which are
101.6 mm apart from each other.
2.
Fix the screws into wall, leaving their heads 3 mm (0.12 inch) clear of the wall surface.
3.
Remove any connections to the unit and locate it over the screw heads.
When in line, gently
push the unit on to the wall and move it downwards to secure.
