FI-502 CLOSE HAULED WIND ANGLE
The FI-501 Wind Angle and FI-502 Close Hauled Wind Angle instru-
ments provide precise analog wind angle together with digital speed in-
dication, in true or apparent direction. Wind speed is displayed in knots,
meters/second or as a Beaufort scale number.
In addition to wind direction and speed indications these instruments pro-
vide:
• Velocity made good (VMG).
• Alarms for minimum and maximum true wind speeds, and high and
low apparent wind angles.

Wind Speed
You can show wind angle and wind speed in apparent or true wind. The
apparent wind is the actual flow of air acting upon a sail, or the wind as
it appears to the sailor. True wind is the wind seen by a stationary ob-
server in velocity and direction.
With a wind angle or wind speed indication displayed, press the APP/
TRUE key to change the wind angle or wind speed to apparent and true
alternately. A beep sounds after the change is completed. (Wind angle
andwind speed displays are mutuallychanged.) Truewind requiresboat
speed input. If there is no speed input three dashes appear.

1.9 Alarms
There are four conditions which trigger audio and visual alarms: Maxi-
mum true wind speed, Low true wind speed, High apparent wind angle,
and Low apparent wind angle.
1. Press the MODE key to select desired alarm page, referring to the
illustration below.
2. If the selected alarm page shows “OFF,” press and hold down the
TACK/CLEAR key until an alarm setting appears.
3. Press the VMG and TACK/CLEAR keys together to enable adjust-
ment. The alarm setting starts flashing.
4. Press the VMG key to lower the setting; the TACK/CLEAR key to
raise it.
Note: A low alarm cannot be set higher than its affiliated high (max.)
alarm.
5. Press the VMG and TACK/CLEAR keys together to confirm setting
and restore normal operation.
When an alarm is violated:
• The display shows current wind speed and angle.
• The buzzer sounds and the alarm icon flashes.
You can silence the buzzer with the TACK/CLEAR key. The alarm icon
continues flashing until the offending alarm is disabled.
While the icon is flashing you can switch between alarm display and cur-
rent display alternately by pressing the MODE and TACK/CLEAR keys
together.

2. FI-505 COURSE PILOT
The FI-505 Course Pilot provides compass heading, in digital format. In
the locked mode, steering error to ±30°deviation of locked course head-
ing is shown, with the analog pointer.
In the unlocked mode the pointer is set to zero. In the locked mode, the
pointer shows course error; that is, the difference between the current
heading and the locked course.

2.5 Unlocked and Locked Heading Modes
In the unlocked mode, the digital display
shows the current heading, true or magnetic,
and the pointer is at zero. The unit always
starts up in the unlocked mode.
In the locked mode, theoperator sets a fixed
(locked) heading, with the arrow keys. The
digital display shows either locked heading or
current heading, depending on calibration set-
ting. The pointer shows the difference be-
tween the locked heading and the actual
course being steered; that is, heading error.
You can switch between the unlock mode and the locked mode with the
ENT key.
Setting locked heading
When you enter the locked mode, the current heading becomes the
locked heading. Then, the digital display shows locked heading or cur-
rent heading, depending on the setup1 menu setting. To change the
locked heading, use the Wkey to shift the heading leftward.
2.6 Resetting Average Heading Indication

3. FI-506 RUDDER
The FI-506 Rudder displays rudder angle, in analog indication. The
pointer shows the rudder position in real time. The instrument’s scale
range is -40°to +40°about zero.
The FI-506 operates in real time, thus almost no action is required of the
operator other than confirming the rudder angle and adjustment of the
brilliance.
