25.8 Fallback Arrangements
If the top priority sensor (e.g. GPS1) can not be used, this equipment automatically
uses the second priority sensor (e.g. GPS2) when the multiple sensors (e.g. GPS1
and GPS2) are installed. When all sensors can not be used, each function is limited
as follows:
Sensor Operation of this equipment
Heading sensor • The HDG indication reads "***.*°".
• The presentation mode is automatically set for head-up.
• TT, AIS, radar map, chart and echo averaging (EAV) are disabled.
Speed sensor When LOG(WT) is selected:
• The sensor used is automatically switched in the following priority order:
GPS(BT) > LOG(BT).
• The SPD indication reads "***.* kn" when both GPS(BT) and LOG(BT)
can not be used.
When LOG(BT) is selected:
• The sensor used is automatically switched in the following priority order:
GPS(BT) > LOG(WT).
• The SPD indication reads "***.* kn" when both GPS(BT) and LOG(WT)
can not be used.
When GPS(BT) is selected:
• The sensor used is automatically switched in the following priority order:
LOG(BT) > LOG(WT).
• The SPD indication reads "***.* kn" when both LOG(BT) and LOG(WT)
can not be used.
COG/SOG sensor • When the GPS sensor can not be used, the values of COG and SOG are
calculated from HDG and LOG(BT).
• Additionally when the heading sensor can not be used, the values of
SOG is calculated from LOG(BT). The COG indication reads "***.*°".
Position sensor • The POSN indication reads all asterisks.
• AIS, radar map and chart are disabled.
