44 Raymarine 37STV Satellite TV System

Note: *for an explanation of the possible causes and their rem-

edies refer to the following 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 coverage areas” on page 47 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 “Planning the installation” on page 8 of

this handbook with regards to your radar unit.

5. Incorrect or loose RF connectors

As part of the regular maintenance recommended by

Raymarine, all connections should be checked to ensure that

they have not become loose. A loose RF connector can reduce

signal quality or cause the antenna not to work.

6. Multi-switch interference

If you have multiple IRD’s connected to your system, make sure

that you are using an ACTIVE not PASSIVE multi-switch.

7. IRD troubleshooting

• Your IRD may be the cause of less than ideal operation.

• Check the IRD’s configuration to ensure that it is pro-

grammed for the area in which you are operating.

• Unplug the IRD from the power supply for 15 seconds.

Reconnect and allow the system to initialize.

8. LNB fault

If you have an LNB fault it may require replacing. Contact your

local dealer, national distributor or Raymarine Product Support

for further assistance.
