Furuno CI-35H - Manual (Page 51)

4-9
NOTE 1
“INT”: Displays date/time of internal clock in CI-
35/35H. Time setting must be done
manually in MENU 2-DATE/TIME. Time
increments in every one second.
“EXT”: Displays date/time received from external
navigator. Generally, time is more accurate
than internal clock, but it may not increment
in one every second.
TIME DATA
NOTE 2
“T/D”: Displays ship’s speed, tide and tide
dif. by using data obtained by CI-
35/35H alone. With “T/D” selected,
pressing TRACK MODE key
changes GT/WT/AUTO.
“NAV-TIDE”: Displays ship’s speed, tide and tide
dif. by referring to the data from
external navigator. With “NAV-TIDE”
selected, pressing TRACK MODE
key changes GT/NAV/AUTO.
WT SPEED
NOTE 3
“CIF”: Furuno CIF format. It is desirable to use
this format to get most accurate nav-tide.
“NMEA”: World standard format. Select this format
only when CIF is not available. (This may
not provide accurate nav-tide because of
its longer update interval.)
NAV FORMAT
NOTE 4
Selects a data source (talker) if multiple nav aids
are connected.
¡ Select “GPS” if available. (Degraded
performance with the other nav aids.)
¡ With NAV DTA set to “ALL”, CI-35/35H
automatically selects a highest priority talker
available.
Priority: GPS>Loran-C>Decca>DR(Satnav)>
Loran-A
NAV AID
NOTE 5
Selects sourse data for pseudo ground tracking
speed.
“L/L”: Calculates speed/course internally from
position data change. (Averaging time
interval can be set in TIME INT.)
“SPD”: Takes speed/course data from external
navigator as they are. (Select “SPD” if
connected with GPS.)
NAV DATA
NOTE 6
If “L/L” is selected as NAV DATA, specify
averaging time interval in TIME INT.
(1 to 10 min in 1 min steps)
Longer interval eliminates display fluctuation of
speed and tide, but the response becomes slower.
1 min will be suitable to work with GPS.

Automatic Course Calibration Procedures
¡ “GT” mode (if ground tracking attainable)
1. Select GT mode by TRACK MODE key.
2. Set CRS MODE to “GT”.
3. Run at around 10 kt keeping same direction.
4. Set cursor on CRS CAL EXEC - “START”,
and press EVENT key. (calibration start)
Course calibration will be completed after you
run 2 n.m.
¡ “NAV” mode (if ground tracking unattainable)
1. Select NAV mode by TRACK MODE key.
2. Set CRS CAL MODE to “NAV”.
3. Run at around 10 kt keeping same direction.
4. Set cursor to CRS CAL EXEC - “START”,
and press EVENT key. (calibration start)
5. When you have run for 5 minutes, turn your
head by 180° and return to the start point.
Course calibration will be completed after you
run 10 minutes. (to go and return)
CRS CAL MODE / CRS CAL EXEC
NOTE 8
Specify data output interval if a data logging device
is connected to AUX port of the transceiver.
(Note that the CIF and NMEA data output intervals
are not affected by this setting.)
