Risk of damage/destruction through low temperatures
The supporting fluid in the gyrosphere container will start freezing at
temperatures below 0° C.
The NAVIGAT X MK 1 must no longer be operated when the ambient tem-
perature at the gyrocompass’ location falls below - 10° C while the com-
pass is in operation or when the ambient temperature falls below 0° C
while the gyrocompass is not in operation.
Always make sure, that the ambient temperature is higher than 0° C
respective 10° C. If this is not possible, the gyrosphere container with
gyrosphere must be removed from the NAVIGAT X MK 1 and transported
to a place with sufficient ambient temperature.
Make sure to remove the gyrosphere from the gyrosphere container if no
place with sufficient ambient temperature is available to eliminate dam-
age from freezing supporting fluid. The removal is to be executed in a
service work procedure by authorized service personnel only.
`^rqflk
Risk of damage through rotating masses
After power-down of the compass system, the gyroscopes need at least
45 minutes to stop rotating. Opening the container or draining off the
supporting fluid during rotating will damage the gyrosphere.
Wait at least 45 minutes after power-down of the compass system and
make sure, that the gyroscopes have stopped rotating before opening the
container or draining off the supporting fluid.
`^rqflk
Risk of damage through inadequate cleaning solvents
Do not clean the compass housing with organic solvents, acetone or any
other substance which could damage or discolour plastic.
Use only soapy water or a mild detergent to clean the compass housing.

`^rqflk
Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the cooling fan and cause over-
heating of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full cooling fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the fan functionality to avoid overheating.
`^rqflk
Risk of damage through unauthorized service
Any service and installation work on the gyrosphere is to be carried out
by authorized service personnel only.
Never undertake service or installation work if unskilled for the certain
procedure.
`^rqflk
Risk of damage through unauthorized service
Only authorized service personnel is allowed to remove the gyrosphere
from the gyrosphere container.
Always keep to the mandatory safety requirements and the correct serv-
ice work procedure to remove the gyrosphere from the gyrosphere con-
tainer.
`^rqflk
Risk of damage through unauthorized service
Only authorized service personnel is allowed to remove gyrocompass

inal transport container.
Do not throw or drop the transport container.
The transport container is to be transported in an upright position only.
`^rqflk
Risk of damage to the gyrosphere
Carry the carrying box containing the gyrosphere by hand only and han-
dle it with extreme care.

diate installation.
`^rqflk
Risk of data loss through shutdown of the compass / power-off condition
After a shutdown of the compasses main and backup power supplies it
cannot be guaranteed that all menu settings remain stored unchanged.
Always check whether the shaft correction angle and alignment error cor-
rection values are noted correctly in the setup tables, before switching-
off the power supplies, see “Setup and Configuration Tables” on page A-
1 Appendix.
Always make sure to separately note the shaft correction angle and align-
ment error correction values before switching-down the compass for
maintenance or repair purposes.

Risk of defective gyrosphere caused by “GYRO FAILURE”
Should a “GYRO FAILURE” alarm occur during power-up, the compass
is not working properly.
De-energize the system and visually check the connections to the gyro-
sphere, the follow-up step motor and the shaft encoder.
If the failure reoccurs when the compass is powered-up again, the instal-
lation has not been carried out correctly or the gyrosphere is defective
and must be replaced.
`^rqflk
Risk of defective gyrosphere
The gyrosphere may not be in operable working condition, if after a time
period of around 45 minutes after power-up the gyrosphere current has
not dropped below 320 mA.
If a visual inspection reveals no obvious cause of malfunction, the power-
up cycle of the gyrosphere must be completely repeated.
If after a time period of around 45 minutes after the second power-up
cycle the gyrosphere current has still not dropped below 320 mA, the
gyrosphere may not be in operable working condition.
Contact the Sperry Marine Service for advice.
`^rqflk
Risk of misleading gyrosphere data / operating values
The temperature and gyrosphere current values are indicated as reading
values at the CDU only.
Both values can be adjusted via correction values, which are set to neu-
tral (= no correction) values by default.
Therefore the indicated values may deviate from real gyrosphere operat-
ing values, which can only be measured at the required checkpoints by
authorized service personnel.
`^rqflk
Risk of inadequate correction values
Any wrongful or not instructed adjustment of the temperature and gyro-
sphere correction values will falsify a correct identification of the
NAVIGAT X MK 1 system‘s operating conditions.
Only authorized service personnel is allowed to change the temperature
and gyrosphere current correction values.
Never alter the correction values unless specifically instructed by Sperry
Marine.
`^rqflk
Risk of inadequate testing / test values
The usage of any voltmeter NOT true RMS for testing will falsify the test
results.
The usage of a multimeter true RMS is absolutely mandatory.
Newer use a voltmeter not true RMS for testing purposes.
`^rqflk
Risk of damage through inadequate operating conditions
Inadequate operating conditions such as e.g. ambient over temperature
or inadequate ventilation, can damage the gyrocompass and decrease
the system performance and the longevity of the system components.
Always keep to the recommended install and environmental conditions
to ensure trouble free operation and best performance of the gyrocom-
pass. Always maintain adequate ventilation at install place.
Additional ventilation may become necessary to meet required ambient
environmental conditions for best performance and system longevity.

Risk of unstable/unreliable heading in polar waters
When operating the vessel in polar waters, the heading information of
the gyrocompass may become unstable/unreliable resulting in possible
deviation.
For safe steering in polar waters, the heading information of the gyro-
compass may therefore NOT be used for navigation and heading infor-
mation of a GNSS (Global Navigation Satellite System) compass be
preferred instead.

The definition of polar waters follows E190E IMO Guidelines for ships
operating in polar waters and is illustrated in
‘Polar Waters Definition” on page 1-9.
`^rqflk
Risk of damage to the gyrosphere through shut-down
A shut down of the NAVIGAT X MK 1 system, while the vessel is navigat-
ing, will damage the gyrosphere, as the gyrosphere is only self protected
against physical damage, as long as the system is running.
NEVER shut down the NAVIGAT X MK 1, while the vessel is navigating.
A shut down of the NAVIGAT X MK 1 system for good reason is only pos-
sible when the ship is NOT navigating.
kçíÉ
Sperry Marine requires to NOT shut down the NAVIGAT X MK 1 system
as long as the vessel is navigating, even when operating in polar waters
with possible unstable/unreliable heading.

Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the cooling fan and cause over-
heating of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full cooling fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the fan functionality to avoid overheating.

In case a „Speed Invalid“ alarm is triggered while the vessel is not in
motion or moving very slowly (e.g. when manoeuvring in harbour), this
is often caused by fast currents of fairway water increasing the - 5.0 kn
minimum speed default value.
In this case, the minimum speed value must be adjusted accordingly.

close to or across the compass housing.
Always make sure to minimise possible electromagnetic interference of
other devices when installing the NAVIGAT X MK 1 gyrocompass.
`^rqflk
Risk of inadequate testing / test values
The usage of any voltmeter NOT true RMS for testing will falsify the test
results.
The usage of a multimeter true RMS is absolutely mandatory.
Newer use a voltmeter not true RMS for testing purposes.
`^rqflk
Risk of damage/destruction after power-down
After power-down of the gyrocompass system, it may take up to
45 minutes for the gyroscopes to stop rotating and the gyrosphere is
therefore extremely sensible against any movement. Should the gyro-
sphere touch the wall of the container, the momentum of the rotating
gyroscopes will make it topple and damage the centre pin.
Avoid any movement of the gyrocompass system during power-down
time. Always be extremely careful in case the gyrosphere container must
be handled during power-down time.
`^rqflk
Risk of damage of electrostatic-discharge-sensitive components

The NAVIGAT X MK 1 is a digital gyrocompass system for the maritime
navigation of vessels and must be operated only from appropriately
trained and educated personnel familiar with all mandatory safety and
operating procedures.
The NAVIGAT X MK 1 provides North-speed error corrected true heading
data as well as rate of turn (ROT) data for the navigation of maritime
vessels.
The NAVIGAT X MK 1 can operate as a standalone system or as part of a
multi gyrocompass system environment (Heading Management Sys-
tem, HMS).
kçí=fåíÉåÇÉÇ=rëÉ
The NAVIGAT X MK 1 and/or the provided true heading and ROT data of
the NAVIGAT X MK 1 are not allowed to be used for the navigation of
inland water vessels and river boats. Any exception to this restriction
must be regulated by specific certification of an entitled organisation or
administration, for further details see certification information under
”Design and Main Features” on page 1-6 and ”Marine Equipment Direc-
tive EC Declaration of Conformity” on page 1-17.
Although the NAVIGAT X MK 1 is a highly accurate system for providing
true heading and ROT data, operators must not rely on it solely as the
only heading source. The plausibility of the NAVIGAT X MK 1 heading
and ROT data and the speed and position input data (as secondary data)
must always be confirmed against all other available aids to navigation.
Since the NAVIGAT X MK 1 system can additionally be used for display-
ing secondary navigation data (speed and position input data) gener-
ated from other connected devices, the operator must not take
displayed secondary data for granted and is obliged to confirm the
validity of secondary data independently.
When navigating in polar waters (according to E190E IMO Guidelines
definition), the heading information of the gyrocompass may become
unstable/unreliable, due to physical principles, resulting in possible
deviation. For safe steering of the vessel in polar waters, the heading
information of the gyrocompass may therefore not be used and heading
information of a GNSS (Global Navigation Satellite System) compass be
preferred instead.
