Maintenance
6-3
Antenna doesn’t track any satellites
(constantly searching)
1. Assure that at least one receiver is ON
2. Check for blockage
3. Assure correct starting elevation
4. May be out of satellite footprint
5. Check all coax cables for poor connection
6. Call dealer/agent for further assistance
Antenna in constant UNWRAP
1. Cycle antenna power OFF/ON to reinitialize the antenna.
2. Call dealer/agent for further assistance
Antenna tracks well at the pier, but
loses the satellite when underway
1. Polarization may not be optimized (refer to section 2.3.1)
2. Call dealer/agent for further assistance
Antenna does not stay on satellite at
pier, or underway
1. Check all coax cables for poor connection
2. Polarization may not be optimized (refer to section 2.3.1)

6.5. Pedestal & PCU Troubleshooting Using Built-In Test (BIT)
The following table is provided to help isolate problems using the Built-In Test (BIT) function in the Coastal
Series Antenna system.
NOTE:
Do NOT run these BIT tests while underway or when the
pedestal base is more than 5 degrees off level.
NOTE: The MODEL parameter setting is saved in the PCU, therefore,
MUST be set whenever the PCU is changed.
WARNING:
Improper setting of the MODEL parameter WILL cause
the antenna to malfunction
.
NOTE: The Serial Number parameter setting is saved in the PCU,
therefore, MUST be set whenever the PCU is changed.
To access the BIT function, turn the antenna system Power OFF at the Display Antenna Control Panel
(DACP). While you Press & Hold the NEXT key, press the POWER key.
After a few seconds, you will see “Built In Test” on the top line of the display and “Press Next to begin” on the
second line. Press NEXT and the BIT tests will begin and run automatically until completed (“BIT Finished
No Errors” will be displayed) or until a test fails. The BIT tests are:
6.5.1. ADC Test
This test checks for basic communication with the Analog-to-Digital Converter on the PCU main board. A
bad A/D could make all other tests fail.
“Testing ADC” will be displayed as the test runs. An Error code 1.01-1.08 will be displayed if one of these
