General Safety Information for the Operator
WARNING
Risk of Deviation
Never rely on the heading indication of an analogue compass repeater
alone to navigate a vessel or to perform other safety-critical operations.
The analogue repeater is an indicator only and will indicate ship’s head-
ing as long as it receives formally valid data. It does not apply any filter-
ing or plausibility checks of the incoming data.
Loss of data supply will result in a visual error indication but will not
raise an audible alarm.
Always confirm the plausibility of the heading indication at the repeater
against the respective source which generates the heading data.
In safety-critical operations, regularly check the data source and the
repeater’s indication against all available aids to navigation.
WARNING
Risk of using magnetic heading data for steering
The magnetic heading repeater is equipped with a removable cover, hid-
ing the compass card when navigating the vessel under normal use, as
the magnetic heading repeater is only classified for steering purposes in
case of emergency with other heading sources not available.
Never remove the cover from the magnetic heading repeater when nav-
igating the vessel under normal use, to avoid steering the vessel mistak-
enly by magnetic compass heading.
WARNING
Risk of using invalid heading data
The heading indication at the repeater is only valid if the error indicator
is off and exactly one of the source indicators is permanently lit.
In case the error indicator in on and one or all of the source indicators
are flashing the heading indication of the repeater must be considered
as invalid and the heading data must not be used for steering the vessel.
WARNING
Risk of injury
Permanent eye damage may result, when looking directly at the sun or
at its reflection in the black azimuth mirror when using the azimuth
device PV 23.
The PV 23 is not suited for taking the azimuth of the sun itself, as the
anti-glare filters do not sufficiently block out direct sunlight.
Never look directly at the sun or at its reflection in the black azimuth mir-
ror when using the azimuth device PV 23.
WARNING
Risk of freeze
The bearing repeater 5016-CA is equipped with capacitive keys, sensi-
tively reacting to the fingers skin resistance which will not function
when touched with gloves.
In case of minus temperatures always be extremely careful not to touch
the metal housing of the bearing repeater to avoid freeze of hands and
fingers.
Note The capacitive keys of the bearing repeater 5016-CA are sensitive against
surface water, e.g. remaining rain drops, which may result in random
changing of the illumination brightness.
This effect does not have any impact on the functionality or handling of
the capacitive keys.
