3. INITIAL SETTINGS
For normal, everyday operation, the [FULL-AUTO] mode is recommended. However,
if you want the NAVpilot to steer the boat based on experience-related parameters,
but you don't want the pilot to be in "self-learning" mode, choose the [SEMI-AUTO]
option.
Note that the course keeping quality may be decreased if the sea state is different
from the experience-related parameters. This option is provided if you happen to be
using the pilot in a situation that you do not anticipate encountering again.
3. For [FULL-AUTO], set the deviation level as follows:
1) Rotate the knob to select [DEVIATION LEVEL] then push the knob.
2) Rotate the knob to select [AUTO] or [LEVEL]. For [LEVEL], you may set a value
between 1 and 9. A lower number keeps the course more precisely but the rudder
may be turned more often. With a higher number, the rudder turns slowly, but the
course may not be kept as precisely.
3) Push the knob to confirm setting.
How to manually set NAVpilot steering parameters
When [MANUAL-CALM], [MANUAL-MODERATE] or [MANUAL-ROUGH] is selected as
the sea state, set [MANUAL PARAMETERS] as below.
You can set three parameters for the MANUAL function: Weather, Rudder gain and
Counter rudder.
1. Rotate the knob to select [MANUAL PARAMETERS] from the [PARAMETER SETUP]
menu then push the knob. The display now looks like the one shown below.
[WEATHER]
[RUDDER GAIN]
[COUNT RUDDER]
2. Rotate the knob to select the setting of [WEATHER-CALM] then press the knob.
3. Rotate the knob to set value (0
4. Push the knob.
5. Set [WEATHER-MODERATE], [WEATHER-ROUGH] and [RUDDER GAIN] and
[COUNT RUDDER] similarly (Setting range: 1-20 for rudder gain, 0-20 for counter rud-
der).
6. Press the MENU key to finish.
Guidelines for how to set SEA STATE
[WEATHER]: When the sea is rough, the boat's heading fluctuates to port and starboard.
If the rudder is driven very often to maintain the set course, the helm mechanism may
wear out. To prevent this, the weather adjustment makes the NAVpilot insensitive to min-
ute course deviations. You may choose a degree between 0? to 10?. Until the course de-
viation exceeds the selected setting, steering to correct the heading will not be initiated.
