Radio Decoder
The radio decoder contains one of the radio units.
The decoder translates the radio traffic, consisting
of lever and button data from the hand controller,
to the CAN bus.
For safety reasons, it is extremely important that data
is not corrupted, therefor the decoder has dual micro-
processors which monitor each other to ensure accu-
racy in the translation. The controller and the decoder
must be "paired" with each other to establish a connec-
tion. A unique code is loaded and stored in each unit.
The pairing procedure is described elsewhere in this
documentation.
A relay box is normally mounted on the bottom
of the decoder. More information regarding
the relay box and its function is provided by
a separate brochure.

Controller
The hand controller is the device that the operator
uses to control his crane and his vehicle.
The hand controller has eight levers. The functions of
each lever may be the same or different in different
menus, however only one function can exist per lever
at any one time.
If a lever is faulty, or if it is deflected on starting, it is
disabled. The other levers operate as usual.
Activating the micro-button enables the operator to set
the levers to 50% or 20% of normal speed thus enabling
the crane to be operated with increased precision.
