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 is not compromised.
Always check the installation before going to sea to make sure that it is not affected by
radio transmissions, engine starting or other forms of interference.
To do this:
1. Turn on all transmitting equipment (radar, VHF radio, etc).
2. Check that all electronic systems are unaffected by interference from the transmit-
ting equipment.
EMC installation guidelines
Raymarine equipment and accessories conform to the appropriate Electromagnetic
Compatibility (EMC) regulations. This minimizes electromagnetic interference
between equipment, which could otherwise affect the performance of your system.
Correct installation is required to ensure that EMC performance is not 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
Make sure you have switched off the power supply before you start
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.
