CAUTION:
The presence of moisture at the rear of the instrument could cause
damage either by entering the instrument through the breathing
hole or by coming into contact with the electrical connectors.
ST60 instruments can be fitted either above or below deck, provided
the rear of the instrument is sited where it is protected from contact
with water.
Each instrument must also be positioned where:
• It is easily read by the helmsman
• It is protected against physical damage
• It is at least 230 mm (9 in) from a compass
• It is at least 500 mm (20 in) from radio receiving equipment
• There is reasonable rear access for installation and servicing

EMC guidelines

All Raytheon 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 EMC 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 this product.
To minimise the risk of operating problems:
• All Raytheon equipment and cables connected to it should be:
• The equipment should be supplied from a different battery than the
• 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 (6 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.
one used for engine start. Voltage drops below 10 V in the power
supply to our products can cause the equipment to reset. This will
not damage the equipment, but will cause the loss of some
information and can change the operating mode.
