A selection box is displayed when you have to choose one of the
parameters or function from those displayed in the box. Current
selection is shown by a "√" mark. To change the selection, move the
" " mark by the trackball and then press the MENU key.
There are three type of alarm setting windows. One is for the
rate-of-turn (R.O.T) speed alarm. Another is for ship's speed and
course, water current speed and direction and wind speed and direction
alarms. The other is for the under-keel clearance, voyage distance and
marker line alarm.
Note: Above alarms do not mean system abnormality. The user sets
them to activate when a preset limit is reached. If any of these alarms
activate, the orange bar appears and the buzzer sounds. Press the
key to stop the buzzer. The orange bar continues to flash until the
normal state is restored.
When the rate-of-turn alarm is selected, the alarm setting window
looks something like the figure shown below, where the gray
barograph shows the present alarm zone setting.
To change the alarm zone:
1. Move the pointer along the bar graph window until the "Cursor"
reads the one of the alarm limit values and then press the MENU
key. The alarm setting window will change as shown below with
the alarm set value set above registered as "Origin".
