Troubleshooting
Possible solutions
In order to obtain a position fix your product requires a GNSS
(GPS) receiver. Your product may include an internal GNSS
(GPS) receiver, if not then an external GNSS (GPS) receiver
such as the RS150 is required.
Depending on variant, your product may include an internal
GNSS (GPS) receiver. The receiver may or may not include
an internal antenna. If your product's internal GNSS (GPS)
receiver does not include an internal antenna then you will
need to connect an external passive antenna to the GNSS
(GPS) / GA150 connection.
For optimum performance, external GNSS (GPS) antennas and
GNSS (GPS) receivers that include an internal antenna should
be mounted above decks and have a clear, unobstructed
view of the sky, and not be in close proximity to any structural
bulkheads or other electrical equipment or cables which may
cause interference.
Ensure your internal GNSS (GPS) receiver is switched on in
the relevant settings menu.
Check periodically to see if a fix is obtained in better
conditions or another geographic location.
Possible solutions
Ensure your external or internal receiver is switched on.
Ensure the correct network type and speed is selected in the
Network output menu: Menu > Set-up > Network output.
1. Check that the connectors are fully inserted into the unit
and locked in position.
2. Check the cables and connectors for signs of damage or
corrosion, replace if necessary.
