Code 14: The Man overboard maneuver can be tuned to run over or close to the object or point at any given speed, but may miss
at another speed. You should probably adjust the maneuver at a speed that is below planing speed. If the object or point passes on
your starboard reduce code 28. See page 15.

Code 15 & 16: Most GPS systems only send cross track error across the NMEA 0183 data bus with .01 mile (60 feet) resolution.
Unfortunately, they display cross track error to the nearest foot. What this means is, don’t expect the autopilot to zero the cross
track error because the information it has is-that any crosstrack error less than 60 ft (as seen on the GPS display) is zero feet. Adjust
parameter 15 up until the boat oscillates back and forth near the course line, then back it down a few clicks. Increase parameter 16
until you can see that standoff from the course line decreases over time.
Use Magnetic North 17 [Up Arrow] for Mag [Down Arrow] for True Heading MAG
Set North 48
In [Standby] Press and hold GPS [Select Load]- if Up Arrow
LED lights, point boat north-then press and release DM
Use Synthetic XTE 167 [Up Arrow] for on, [Down Arrow] for off On
Code 167: On some GPS’ this code may result in tighter tracking near waypoints.
Use NMEA Checksum 347 [Up Arrow] for on, [Down Arrow] for off On
Code 347: If your GPS calculates checksums wrong, you may still be able to use it with this code turned off. Data
integrity is compromised in this condition.
Use Reversed XTE 18 [Up Arrow] for on, [Down Arrow] for off Off
Code 18: Some GPS’ send the wrong direction to steer with the crosstrack error signal. Use this code to x this
problem.
Use GPS 1 GPS 2 34 [Up Arrow] for 2, [Down Arrow] for 1 1
Code 34: This code switches between the two sources of NMEA navigation data used by the autopilot to steer with.
Update rate for HDG out 49 0 (off) to 10 HZ Update Rate 10 HZ
Code 49:
With this code at the bottom of its range (Down Arrow LED on) the autopilot does not transmit $APHDG. With
any settings other than off, the data is transmitted at a rate equal to (1-code 49 setting) HZ. up to a maximum rate of 10 Hz.
Fine Heading Adjust 168
[Up Arrow] increase heading out .1 deg. [Down Arrow] decreases heading
out .1 deg. Note: Very Slow response to buttons.
