into the back box, taking care that the CAT-5 cable(s) and PSU wiring (if used) are
not under any strain. Insert the two M3.5 raised-head screws supplied through
the xing holes in the front plate and engage them in the threaded inserts or lugs
of the back box. Tighten until the panel is neatly ush against the wall – do NOT
over-tighten.
Without back box: carefully position the rear of the unit in the hole, and x the
front panel with screws of a type and length appropriate to the wall construction.
No. 6 woodscrews are satisfactory provided that timber battens are available
either side of the hole.
