Preventive maintenance
The NSO unit does not contain any field serviceable components, therefore the operator
is required to perform only a very limited amount of preventative maintenance.
It is recommended that you always fit the supplied protective sun cover when the unit is
not in use.
Simple maintenance procedures
Cleaning the display unit
Clean the housing and the front glass of the display and OP40 unit with a damp cloth and
mild detergent.
Checking the keys
Make sure that no keys are stuck in the down position. However, if one is stuck, wiggle
the key to free it back to normal.
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 this is in the correct position.
Software upgrades
The latest software for the NSO will be available for download from our website;
www.simrad-yaching.com.
Detailed instructions for how to install the software will follow the upgrade files.
For more details about software upgrades, refer to the separate Installation manual.
Backing up your system data
Waypoints, routes, tracks that you create on your system are filed on your system. It is
recommended to regularly export these files and your settings file as part of your back-
up routine.
The files are exported to an SD card inserted in the separate card reader.
An illustration on the next page shows the process when exporting waypoints, routes
and tracks. Other files are exported by the same process.
