Chapter 3: Installation
3.1 Introduction
Please read this chapter thoroughly before attempting to install the
instrument and transducer. Always use genuine Raymarine cables. The
use of unapproved/inferior cables, for which Raymarine cannot be held
liable, could affect the performance of the Bidata and other instruments
on the SeaTalk bus.
The Bidata may be flush mounted by installing the instrument from
behind the instrument panel.
The display bezel must not be
assembled to the instrument if the Bidata is to be flush mounted.
EMC installation guidelines
All Raymarine equipment and accessories are designed to the best
industry standards for use in the leisure marine environment.
Their design and manufacture conforms to the appropriate
Electromagnetic Compatibility (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.
The guidelines given here 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.
