Maintenance
Preventive maintenance
The unit does not contain any field serviceable components. Therefore, the operator is
required to perform only a very limited amount of preventative maintenance.
If a sun cover is available, it is recommended that you always fit it when the unit is not in use.
Cleaning the display unit
To clean the screen:
• A micro-fiber or a soft cotton cloth should be used to clean the screen. Use plenty of
water to dissolve and take away salt remains. Crystallized salt, sand, dirt, etc. can scratch
the protective coating if using a damp cloth. Use a light fresh water spray then wipe the
unit dry with a micro-fiber or a soft cotton cloth. Do not apply pressure with the cloth.
To clean the housing:
• Use warm water with a dash of liquid dish soap or detergent.
Avoid using abrasive cleaning products or products containing solvents (acetone, mineral
turpentine, etc.), acid, ammonia, or alcohol as they can damage the display and plastic
housing.
Do not use a jet or high pressure wash. Do not run your unit through a car wash.
Checking the connectors
The connectors should be checked by visual inspection only.
Push the connector plugs into the connector. If the connector plugs are equipped with a
lock, ensure that it is in the correct position.
NMEA Data logging
All serial output sentences sent over the NMEA TCP connection are logged to an internal file.
You can export and review this file for service and fault finding purposes.
The maximum file size is predefined. If you have added several other files to the system (file
recordings, music, pictures, PDF files), this may reduce the allowed file size for the log file.
The system logs as much data as possible within the file size limitation, and then it starts
overwriting the oldest data.
Exporting the log file
The log file can be exported from the files dialog.
When you select the Log database you are prompted to select a destination folder and
filename. Once accepted, the log file is written to the chosen location.
