4.5.4.3 Setting the Anchor Alarm Range
An alarm can be activated when the vessel has drifted out of the preset destination range.
Normally, the anchor alarm is set to the anchor point being as the destination and to inform the steersman
that the vessel has drifted beyond a preset distance from the destination.
At first, set a given position that needs to be maintained as the destination by following the steps described
under the item 4.3.1.1 “Setting a Destination”.
In case it is necessary to register the current position as the destination, use the event function to set a
destination number to it. (See the item 4.3.1.5 “Storing the Current Position”)
Example) In case it is necessary to activate the alarm when the vessel has drifted by 0.05 nm or more from
the anchor point. (See the figure shown below.)
・ Press the key provided on the right hand side of the ANCHOR, and then the 0 , 0 , 5 , and
ENT keys.
Memo
・ Pressing the CLR key will turn off the alarm sound, however, the alarm display will remain turned on
unless the vessel has returned back into the preset alarm range or the a new setting range is entered.
・ No alarm goes off when the alarm range is set to zero nm.
・ The arrival alarm and anchor alarm function can not be set simultaneously since they contradict each
other. Setting one alarm will automatically cancel the other.
