andType150/400coursecomputers.Itprovidesthecoursecomputer
with precise information aboutthe boat’s yaw (its rate of turn). The
course computer uses this information to improve course keeping:
•Type150/400course computers:connecting the GyroPlus
enablesnineresponse levels, providesenhanced coursekeeping
usingAST(AdvancedSteering Technology).It also allows
accesstoAutoLearn (self-learning steeringcalibration) when
usedwithST6001+orST7001+controlunits.
•Type100/300course computers:connecting the GyroPlus
enhances performance with the autopilot set to response level3.
Autopilot operation in response levels 1 and 2 is unchanged.

Installing the GyroPlus
Location
Mount the GyroPlus rate sensor below deck, in a location that is:
•vertical (seebelow)
•dry
•protected
•freefrom vibration
Note:When selectingthe location for the GyroPlus sensor and the
route for the cable, refer to EMC (Electro-Magnetic Compatibility)
information suppliedwith coursecomputer.

Post-installation procedures
AfterconnectingaGyroPlus sensor, you MUST completethese
2 procedures:
1. Offset anddrift compensation
2. Coursecomputerre-calibration
Offset and drift compensation
Like all rate gyros, the GyroPlus issubject to offset and drift. If you
complete the following steps after installing theGyroPlus, your
Raymarine autopilots will be able to compensate automatically for
this offset and drift in Auto mode:
1. Moortheboatsotheheadingremainsconstant.
2. Pressauto to enter Auto mode.
3. Leave the autopilotin Auto mode for 5 minutes so the course
computer candetermine the necessaryoffset anddrift
compensationvalues.
4. After5 minutespressstandby to return toStandby mode. The
course computer will store the compensation values.
Course computer re-calibration
AfterinstallingaGyroPlusyouMUSTre-calibratetheautopilot.
If you havean ST6001+ or ST7001+ control unit you will be able to
use the AutoLearn steering calibration function.
Refer to the control unit owner’s handbook for more information
about calibratingthe course computer.

Raymarine EMC Guidelines
EMC Installation & Service Guidelines
IMPORTANT NOTE
All Raymarine equipment and accessories are designed to the best industry standards for
use in the leisure marine environment.
When powered up, all electrical equipment produces electromagnetic fields. These can
cause adjacent pieces of electrical equipment to interact with one another, with a
consequent adverse effect on operation. In order to minimise these effects and enable you
to get the best possible performance from your Raymarine equipment, these guidelines are
provided to enable you to ensure minimum interaction between different items of
equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).
The design and manufacture of Raymarine equipment and accessories conform to the
appropriate EMC standards, but correct installation is required to ensure that performance
is not compromised. Although every effort has been taken to ensure that they will perform
under all conditions, it is important to understand what factors could affect the operation of
the product. Please keep this document for future reference.
Safety
Some products generate high voltages, so never handle the cables/connectors when power
is being supplied to the equipment.
Installation
These guidelines describe the conditions for optimum EMC performance, but it is
recognised that it may not be possible to meet all of these conditions in all situations. To
ensure the best possible conditions for EMC performance within the constraints imposed
by any location, always ensure the maximum separation possible between different items
of electrical equipment.
For optimum EMC performance, it is recommended that wherever possible:
• Raymarine equipment and cables connected to it are:
• At least 1 m (3 ft) from any equipment transmitting or cables carrying radio signals
e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance
should be increased to 2 m (7 ft).
• More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally be
assumed to spread 20 degrees above and below the radiating element.
• The equipment is supplied from a separate battery from that used for engine start.
Voltage drops below 10 V in the power supply to our products, and starter motor
transients, can cause the equipment to reset. This will not damage the equipment, but
may cause the loss of some information and may change the operating mode.

Raymarine EMC Guidelines
• Raymarine specified cables are used at all times. Cutting and rejoining these cables can
compromise EMC performance and so must be avoided unless doing so is detailed in
the installation manual.
• If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the
ferrite needs to be removed during installation it must be reassembled in the same
position.
Suppression Ferrites
The following illustration shows typical cable suppression ferrites fitted to Raymarine
equipment. Always use the ferrites supplied by Raymarine.
D3548-2
Connections to Other Equipment
If your Raymarine equipment is to be connected to other equipment using a cable not
supplied by Raymarine, a suppression ferrite MUST always be fitted to the cable close to
the Raymarine unit.
Check Before Going to Sea
Always check the installation before going to sea to make sure that it is not affected by
radio transmissions, engine starting etc.
Servicing
Raymarine equipment should be serviced only by authorised Raymarine service
technicians. They will ensure that service procedures and replacement parts used will not
affect performance. There are no user serviceable parts in any Raymarine product.
Always report any EMC related problem to your nearest Raymarine dealer. We use such
information to improve our quality standards.
In some installations it may not be possible to prevent equipment from being affected by
external influences. In general this will not damage the equipment but it can lead to
spurious resetting action, or momentarily may result in faulty operation.
