Sensitivity Adjustment
Press the soft key labeled "SENS." (for sensitivity) to
bring up the choices available for adjusting the
Advantage's receiver sensitivity. Press the button
labeled "AUTO" so that the word AUTO is shown in
reverse video (white letters on a black background) if you
would like the Advantage to automatically adjust its
sensitivity for changing conditions. To manually adjust
the sensitivity press the button labeled “Sens.+” or “-
Sens” to increase or decrease the receiver gain. Note that
the soft key shows a number which indicates the relative
sensitivity being used. When you choose to manually
adjust the sensitivity, the Advantage turns off the AUTO
sensitivity mode and it will remain off until the “AUTO”
soft key is again selected. Note: when AUTO mode is
turned on the word AUTO will be displayed in reverse
video (white letters on a black background). To exit the
sensitivity menu and save your adjustments simply press
the soft key labeled “LAST” to return to the main menu.
(Press "MENU" to then return to the Control Center).
Alarm Adjustment
In the scanning display or view, an alarm may be set for
targets which are closer than a present distance.
To adjust or clear the alarm settings, press the soft key
labeled “ALARM” to bring up the alarm menu choices.
As either the up or down keys are pressed and held down,
or the large knob is rotated counterclockwise , a
horizontal bar will move from the bottom of the display
towards the top. A vertical bar will also move along the
range scale. The horizontal and vertical bar indicate the
alarm range. Any strong target between the boat (at the
top of the display) and the alarm bar will cause the alarm
to sound. (Note: the horizontal line will disappear a few
seconds after the alarm is adjusted, but the vertical bar
will remain to indicate the alarms setting.)
To deactivate the alarm either press the "CLEAR" soft
key to clear the alarm, or rotate the control knob
clockwise until the alarm bar disappears at the bottom of
the display.
