Polarisation setting
The polarisations setting is required to compensate for the so-called
skew
. The skew is the discrepancy
between the vertical polarisation of the received signal from the geographical verticals. For optimal recep-
tion the LNB must be installed before the satellite disk, inclined by the
skew angle
.
The CAP 920 calculates the skew angle on the basis of the GPS data and inclines the LNB fully automati-
cally. The prerequisite for this is that valid GPS data are available.

Manual lowering to park position
Caution
Danger of injury and even death from
– roof collapsing,
– falling,
– falling parts in the motor home,
– movements of the turntable.
Please note in particular that:
●
The antenna and connected units are disconnected from the power,
●
The person carrying out the repair does not suffer from vertigo and can
move around safely on the roof of the caravan or motor home,
●
The person carrying out the repairs is wearing sturdy non-slip shoes,
●
The person carrying out the repairs has a secure position to stand and hold
on while working,
●
The roof and the climbing equipment used (e.g. ladder) are dry, clean and
non-slip,
●
The roof can withstand the weight of the person carrying out the repairs,
●
Do not hold onto the antenna, as the rocker can come free without warning
during dismantling,
●
Nobody should be underneath the antenna inside the caravan / motor home
during dismantling / installation.

Safety instructions
Important
●
If a defect arises in the electronic controls, after some disassembly work the satellite dish can
be returned to the park position (horizontal position) manually. Following this, however, recali-
bration by an authorised workshop is always necessary.
● Driving to the nearest workshop at a moderate speed with the antenna extended and taking
into account the increase (+79 cm) in the vehicle height is an option and is preferable to man-
ual lowering.
●
Users unfamiliar with the necessary repair work are urged not to attempt to lower the antenna
manually into the park position themselves. They should contact a technician or engineer. They
may find a suitable person on the campsite.
●
Always follow the safety instructions listed below.
