Warnings and cautions
Electromagnetic Compatibility (EMC) conformance
Raymarine equipment and accessories conform to the appropriate Electromagnetic
Compatibility(EMC)regulations for use in the recreational marine environment.
Correct installation is required to ensure that EMC performance isnot compromised.
Alwayschecktheinstallationbeforegoingtoseatomakesurethatitisnotaffectedby
radio transmissions, engine starting or other forms of interference.
To do this:
1. Turn on all transmitting equipment (radar, VHF radio, etc).
2. Checkthatallelectronicsystemsareunaffectedbyinterferencefromthetransmit-
ting equipment.
EMC installation guidelines
Raymarine equipment and accessories conform to the appropriate Electromagnetic
Compatibility (EMC) regulations. This minimizes electromagneticinterference
between equipment, which could otherwise affect the performance of yoursystem.
Correct installation is required to ensure that EMC performance isnot compromised.
For optimum EMC performance, we make the following recommendations:
WARNING: Product installation and operation
This equipment must be installed, commissioned and operated in
accordance with the Raymarine instructions provided. Failure to
do so could result in personal injury, damage to your boat and/or
poor product performance. Before you install the ST70
instrument, check that individual components are the correct
voltage for your boat’s supply.
WARNING: Electrical safety
Makesureyouhaveswitchedoffthepowersupplybeforeyoustart
installing this product.
WARNING: Navigational safety
Although we have designed this product to be accurate and
reliable, many factors can affect its performance. Therefore, it
should serve only as an aid to navigation and should never replace
commonsense and navigational judgement. Always maintain a
permanent watch so you can respond to situations as they
develop.

• PlaceRaymarineequipmentandcablesatleast3ft(1m)fromanyequipmentthat
transmits,orcables thatcarry,radio signals from VHF radios, cablesand anten-
nas. In the case of SSBradios, the distance should beincreased to 7 ft. (2m).
• Place Raymarine equipment and cables more than 7 ft(2 m) from the path of a
radarbeam.Aradarbeamcannormallybeassumedtospread20degreesabove
and below the radiating element.
• Use a power source separate from that used forengine-start.This is important to
preventerraticbehavioranddatalosswhichcanoccuriftheengine-startdoesnot
have a separate battery.
• Use Raymarine-specified cables.
• Do not cut or extend cables unless doing so is detailed in the installation manual.
Remember
Where constraints on the installation prevent any of the above recommendations:
• Alwaysallow themaximumseparationpossible betweendifferentitemsofelectri-
cal equipment.
This will provide the best conditions for good EMC performance of the installation.
Suppression ferrites
Raymarine cables may be fitted with suppression ferrites. These are necessary for
correct EMC performance. Any ferrite removed during installation mustbe replaced
assoon as installation is complete.
Use only ferrites of the correct type, supplied by Raymarine authorized dealers.
Connections to other equipment
If Raymarine equipment is to be connected to other equipment using a cable not
supplied by Raymarine, a Raymarine suppression ferrite MUST always be attached
to the cable near the Raymarine unit.
EMC Servicing and maintenance
• Undue noise and interference may be a symptom of an EMC-related problem.
Please report any EMC-related problem to your nearest Raymarine dealer. We
use such information to improve our quality standards.
• To minimize any EMC related problems and ensure the best possible perfor-
mance form your Raymarine equipment, follow the guidelines given in the instal-
lation instructions.
