7 Troubleshooting
If you notice unexpected operation of the Maretron SSC300, follow the troubleshooting
procedures in this section to remedy simple problems.
Symptom
No heading output
Inaccurate heading output
If these steps do not solve your problem, please contact Maretron Technical Support (refer to
Section 9 for contact information).
Warning: There are no user-serviceable components inside the Maretron SSC300.
Opening the SSC300 will expose the sensitive electronic components to movement and
adverse environmental conditions that may render the compass inoperative. Please do
not open the SSC300, as this will automatically void the warranty. If service is required,
please return the unit to an authorized Maretron service location.

Troubleshooting Procedure
Check the connections to the NMEA 2000
connector and/or NMEA 0183 Connector and tighten if
necessary
Ensure that power is supplied to the connected NMEA
®
2000
or NMEA 0183 cable
For NMEA 0183 connections, ensure that the SSC300
is programmed to transmit the appropriate type of
sentence (HDT, HDG, or HDM) required by the
connected equipment.
If the HDT sentence is being transmitted, ensure that
the SSC300 is provided with a source of magnetic
variation information so that it can calculate true
heading from the magnetic heading.
Ensure the SSC300 is still mounted securely
Ensure the SSC300 is still in a clean magnetic
environment and that no power or ignition cables or
magnetic or ferrous objects have been moved near the
SSC300
Repeat the magnetic deviation compensation and
installation-offset correction procedures
