Manual Speed Input - Furuno FAR-2218-BB Operator's Manual

• Be sure not to select a [LOG] option when a speed log is not connected. If the log
signal is not provided, the ship speed readout at the top of the screen will be blank.
In the event of a log error, enter speed manually.
• The [SPD] is shown as "*.* kn" and the label "NO LOG(BT) SIGNAL" or "NO
LOG(WT) SIGNAL" (in yellow-orange) appears and the alert buzzer sounds if no log
signal is present for 30 s.
• When the speed input in use is interrupted or lost, the system automatically chang-
es to another speed input (stabilization reference) and outputs the "SPD SOURCE
CHG" alert.
• On IMO-type radars with AIS in use, [MANUAL] and [REF] are shown in gray to in-
dicate they are not available for selection.
• A single-axis water log cannot measure speed when the wind is coming from the
leeway direction.
• When [ECDIS] is selected as the speed data source and communication with the
ECDIS is interrupted or lost for 30 seconds, the Alert "ECDIS COM ERROR" is re-
leased.
• When speed stabilization is changed at the ECDIS and [ECDIS] is selected as the
speed data source, the Alert "SPD SOURCE CHG" is released.
