* for an explanation of possible causes and their remedies refer to the following
Note:
paragraphs.
1. Blown fuse, low power or wiring
• Check that the in-line quick blow fuse (if fitted) has not blown, or the circuit
breaker has not tripped. Replace fuse with one of the same type and rating.
• If you have extended the power cable from the antenna unit, check that there
is no power loss.
• Check the system wiring and connections.
2. Satellite signal blocked
Satellite signals can be blocked or degraded by buildings, other boats, or
equipment on your boat. Check that the antenna has a clear view of the sky.
3. Outside satellite coverage zone
Your system will provide excellent reception within the antenna coverage area for
your satellite television service. However, signal quality may degrade as you
approach the edges of this zone. Refer to "Satellite information" on page 57 to
check the viable coverage area for your antenna.
4. Radar interference
The energy levels radiated by radar units can overload the antenna front-end
circuits. Make sure that your antenna is installed as described in "How do I plan
the installation?...." on page 10 of this handbook with regards to your radar unit.
