Siting
The control head is completely waterproof and should be sited where it
is:
• Within easy reach of the steering position
• Protected from physical damage
• At least 230 mm (9 in) from any compass
• At least 1 m (3 ft) from any radio/radar receiving/transmitting
equipment
• Mounted with sufficient space behind the bulkhead to install the
cables
Note: The back cover is designed to breath through the cable boss to
prevent moisture accumulation. This must be protected from the
weather by following the mounting procedure.
Mounting procedure
Control heads are available in surface mount and flush mount styles.
Use the appropriate procedure to mount your instrument, but in each
case, ensure that:
• The selected location is clean, smooth and flat.
• There is sufficient space behind the selected location to
accommodate the rear of the control head and connectors.
