Unit Installation Adjustment
Installing the ONU on a horizontal surface (Bench top)
Put the ONU on a clean, flat, sturdy bench top. You must keep the clearance for all sides
of the unit to more than 10cm for heat dissipation.
Installing the ONU on a vertical surface (Hanging on a wall)
You can install the ONU on a vertical surface by using the mounting holes on the bottom
of the ONU chassis and two flat-head wood screws.
a) Insert the screws into the wall. The screw positions must be in the same horizontal line
and the distance between them must be 145mm. Reserved at least 6mm between the
screw caps and the wall.
b) Hang the ONU on the screws through the mounting holes.
