TROUBLESHOOTING
If you notice unexpected operation of the SSHS, follow the troubleshooting procedures in this
section to remedy simple problems.
If these steps do not solve your problem, please contact Technical Support (see the
Back
Cover
of this manual for contact information).
Warning:
There are no user-serviceable components inside the SSHS. Opening the
SSHS will expose the sensitive electronic components to movement and adverse
environmental conditions that may render the compass inoperative. Please do not
open the SSHS, as this will automatically void the warranty. If service is required, please
return the unit to an authorized Jeppesen Marine service location (see
Page 38
).
Symptom Troubleshooting Procedure
No heading output • Check the connections to the NMEA 0183 connector and / or
NMEA 2000 connector and tighten if necessary.
• Ensure that power is supplied to the connected NMEA 2000
or NMEA 0183 cable
Inaccurate heading output • Ensure the SSHS is still mounted securely.
• Ensure the SSHS is still in a clean magnetic environment and
that no power or ignition cables or magnetic or ferrous objects
have been moved near the SSHS
