18 Installation
Correct installation is critical to the performance of the unit. It is vital to read the entire installation section of this manual and the documentation that comes with the antenna and any other units before starting installation.
! WARNING
Ensure that any holes cut are in a safe position and will not weaken the boat’s structure. If in doubt, consult a qualified boat builder.
CAUTION
Do not mount any part where it can be used as a hand hold, where it might be submerged or where it will interfere with the operation, launching or retrieving of the boat.
To help ensure proper operation, do not mount any part or cable within 0.5 m (20”) of the plane of a radar antenna or within 1 m (3 ft) of a compass or source of electrical noise, such as engines, fluorescent lights, and power inverters.
When fitting a cable, do not crush or strain the cable. Secure the cable at regular intervals. Ensure no connectors or exposed terminals are in wet area.
If the cables supplied are too long, do not shorten the cable; instead coil the cable. Most cables can be extended with Northstar extension cables. Do not fit more than one extension cable.
