3.4.4 Halcyon 2000 Calibration Procedure
(1) Check for any magnetic devices placed near the
compass, especially ones that are out of their normal
places.
(2) On a calm day select a stretch of open water with
little traffic (so you will not have to take avoiding action
that would ruin the calibration). The flatter the water and
the less the wind the easier it will be to meet the
conditions for calibration.
(3) Check for any large steel structures nearby, that may
cause additional, erratic deviations.
(4) Scroll to the NAVIGATE menu and select COMP
CAL on the top half of the display. The display shows
OFF.
(5) Press Scroll Down until the lower text shows
CALBRATE flashing.
(6) Press the Enter key twice to display START and a
default setting of ‘0’.
(7) Press the Enter key once and the ‘0’ starts to flash.
Use the Scroll Up key to change the value to ‘1’.
(8) Press the Enter key. The display now shows 000
°
.
(9) At a speed not exceeding five knots, turn the boat
through 360
°
at a rate not greater than 2-3
°
per second.
