1.1 Siting
The ST30 Bidata instrument may be installed above or below deck where
it is:
• easily read by the helmsman (normally viewed at eye level)
• protected from physical damage
• at least 230mm (9in) from a compass
• at least 500mm (20in) from radio receiving equipment
• accessible from behind for ease of installation and cable running
Notes: To prevent the build-up of moisture, the instrument breathes
through the back cover. The instrument must, therefore, be mounted
where the back cover is protected from direct water.
The rear case is fitted with a foam gasket to form a water-tight seal
between the instrument and the installation face.
