3.3 MINIMUM CLEARANCE
Irrespective of the mounting type or scenario, the D2O must have a minimum
clearance to the nearest object to avoid Radio Frequency (RF) interference
and adverse Antenna influence.
With the exception of the mounting device itself (post, mast etc.), there should
be no other surfaces or objects within 150mm below the base of the D2O unit
and 500mm radially from the centre of the unit as per the diagram.

As a first step the
Antenna
must be installed on the D2O unit before it will
function.
The
Antenna
is then attached by screwing it on the exposed
Antenna Base
thread on the top of the D2O unit. It should be tightened until the
Antenna
contacts the D2O Unit. Do not over-tighten the Antenna as irreparable
damage may occur.
