Troubleshooting A
Intermittent loss of lock
The receiver loses the satellite signal
from time to time. Check that all cable connections are secure and
free of moisture. If necessary, disconnect the cables
and allow them to dry. Then reconnect the cables.
Make sure that the receiver is mounted on the
highest point of the vessel, and is clear of metal
surfaces.
Try traveling in a different direction.
Check Maximum PDOP and Minimum Signal
Strength settings (see Poor accuracy above).
Intermittent DGPS signal
The correction signal strength can be
reduced to unusable levels. Causes
include tree canopy cover between
the receiver and the differential
satellite, radar sets, and microwave
transmitters. Make sure that the receiver is mounted away from
overhead trees and sources of electromagnetic
interference.
Not tracking satellites or
differential signal
The receiver is not tracking satellites,
and the Home screen displays
(Sv:00). The receiver is searching for
a satellite or beacon signal. Check the cable connections at the receiver and
antenna.
