When wall mounting the unit, ensure that it is within reach of the power outlet.
You will need two suitable screws to wall mount the unit. To do this:
1 Ensure that the wall you use is smooth, flat, dry and sturdy and make two
screw holes which are 150 mm (5.9 in.) apart.
2 Fix the screws into the wall, leaving their heads 3 mm (0.12 in.) 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.
When making connections, be careful not to push the unit up and off the wall.
CAUTION: Only wall mount single units, do not wall mount stacked units.
